class="center">Augochlora callichlorura, new species

♀.—Length a little over 7 mm.; first two abdominal segments rather weakly vibrissate on hind margin with orange hairs; hind spur of hind leg with long spines. Head and thorax very dark purplish, nearly black, but a blue-green spot at upper end of clypeus, supraclypeal area brilliant purple, and base of metathorax strongly tinged with purple; anterior and middle legs dark, with weak purple tints, but hind femora, tibiæ and basal half of basitarsi all brilliant green on outer side; abdomen short and broad, shining, very brilliant emerald green. Head broad, eyes strongly converging below; clypeus with extremely large punctures; front dull and granular; ocelli ordinary; cheeks with thin white hair; mesothorax and scutellum shining, but well punctured; base of metathorax with strong short plicæ; angles of prothorax not prominent; tegulæ rufotestaceous; wings grayish translucent, stigma and nervures dusky pale brown; first recurrent nervure meeting second transversocubital; abdomen with thin pale hair, hind margins of segments not darkened. Bartica District.

Unique by the combination of purplish head and thorax and green abdomen, the general effect recalling A. atropos Smith.

Florilegus barticanus, new species.

♂.—Length about 11 mm.; black, except as follows: first abdominal segment strongly greenish; clypeus and labrum entirely yellow; mandibles fulvous apically (but base black); antennæ, except the first two joints, ferruginous beneath; hind tarsi, and apex of hind tibiæ, dusky red; hair of head and thorax ferruginous, paler below, no admixture of dark hairs; eyes reddish; mesothorax shining, but distinctly punctured; tegulæ clear ferruginous; wings dusky hyaline, nervures reddish fuscous; legs with pale hair, conspicuously plumose on hind tibiæ; abdomen with four broad dense ochraceous hair-bands, that on fourth segment broadly excavated in middle posteriorly, on fifth broadly interrupted; sixth segment with a small patch of fulvous hair on each side; apical part of abdomen dorsally, except for the bands and patches, with very dark fuscous hair. Bartica District (Hym. 11).

Related to F. lanieri Guér. from Cuba and F. condigna Cresson from the United States. In the coloration of the legs it is intermediate between these two.

Tetrapedia lacteipennis Vachal.—It should be added to Vachal's description, that the dorsal abdominal segments 2 to 4 have yellow bands.

The Bartica collection contains a Megalopta from Hoorie, but it is unfortunately broken. I have Megalopta panamensis Cockerell from Maroni, French Guiana (Queensland Museum, 42).

I add the description of a new species from French Guiana, the type of which is in my collection.

Augochlora maroniana, new species

♀.—Length slightly over 8 mm.; head, thorax and legs bright green; abdomen yellowish green strongly suffused with coppery, the first two segments with apical fringes of orange hair; face rather narrow; antennæ black; lower middle of clypeus black; mesothorax and scutellum rough with dense punctatures, the scutellum with two copper-red spots; area of metathorax with very feeble plicæ; tegulæ black with pallid margin, the basal side broadly green; wings dusky; second s. m. square; first r. n. meeting second t. c; stigma dusky reddish; legs with mainly pale hair, hind tibiæ with dark hair on outer side basally; hind spur with about six long spines; basal half of basitarsi green on outer side; abdomen shining, with pale ochreus hair.

Maroni, French Guiana (Queensland Mus., 43). Related to A. cupreola (Ckll.), but with the vibrissate fringes on abdomen nearly twice as long, and deep orange-fulvous, and the mesothorax much more densely punctured. Also related to A. diversipennis (Lep.), but with the face much narrower, and the area of
