Journal of Entomology and Zoology

EDITED BY POMONA COLLEGE, DEPARTMENT OF ZOOLOGY

Subscription $1.00 to domestic, $1.25 to foreign countries.

This journal is especially offered in exchange for zoological and entomological journals, proceedings, transactions, reports of societies, museums, laboratories and expeditions.

The pages of the journal are especially open to western entomologists and zoologists. Notes and papers relating to western and Californian forms and conditions are particularly desired, but short morphological, systematic or economic studies from any locality will be considered for publication.

Manuscripts submitted should be typewritten on one side of paper about 8 by 11 inches. Foot notes, tables, explanations of figures, etc., should be written on separate sheets. Foot notes and figures should be numbered consecutively throughout. The desired position of foot notes and figures should be clearly indicated in the manuscript.

Figures should be drawn so that they may be reproduced as line cuts so far as possible. An unusually large number of half tones must be paid for in part by the author. Other more expensive illustrations will be furnished at cost. Figures for cuts should be made to conform to the size of the page when reduced, that is, 5 by 7-1/2 inches or less. The lettering should be by means of printed numbers and letters pasted on the drawings, in most cases.

Authors of articles longer than a thousand words will receive fifty reprints of their publications free of cost. If more than this are desired, the order should be given with the return of the proof sheets. Extra copies and special covers or special paper will be furnished at cost. Authors of short contributions will receive a few extra copies of the number containing their articles.

Manuscripts should be sent by express or registered mail.

Another Record of a Small Whip Scorpion in California

M. L. MOLES

In April, 1916, Dr. W. A. Hilton collected some small whip-scorpions in the Pomona College Park at Claremont. These creatures were without eyes and yet they seemed to avoid forceps. They were able to run backwards or forwards with equal ease. On examination it was found that there were long hairs on the legs such as shown in the figure. Other specimens were afterwards found in one of the nearby canyons, and two specimens in the college collection were marked “C. Metz, in the mountains near Claremont.”

Upon looking through the literature the species was determined to be Trithyreus pentapeltis Cook. In 1899 Dr. Hubbard collected some at Palm Springs under stones in the canyon near the stream. Those which we have found this year were under the dried oak leaves some distance from water. Cook gave the generic name Hubbardia which has not been sustained.

The following are the measurements of two types of the twenty or more specimens found.

Measurements—supposed Male:

Length of whole body, 7.5 mm.
Length of cephalothorax, 2 mm.
Length of abdomen, 3 mm.
Length of tail, 2.5 mm.
Length of first leg, 8 mm.
Length of maxillæ, 1.5 mm.
Width of abdomen, 1 mm.
Width of cephalothorax, 8 mm.

Measurements—Supposed Female and Juvenile, Fig. 1:

Length of whole body, 4.5 mm.
Length of cephalothorax, 1.5 mm.
Length of abdomen, 2 mm.
Length of tail, 1 mm.
Length of first leg, 5.5 mm.
Length of maxillæ, 2 mm.
Width of cephalothorax, 6 mm.
Width of abdomen, 1 mm.

Color of supposed Male—Cephalothorax and maxillæ, dark reddish brown.
