annae Ckll., with which Professor Cockerell at first supposed it to he 
identical. It was also found by me plentifully in the Sacramento 
Mountains, on Gutierrezia sarothrae, October 2, 1896, on the Rio Tula- 
rosa, 6200 feet, along with Icerya townsendi and Dactylopius gutierreziae. 
Stictocephala inermis Pah. — Gila Hot Springs, July 20. (Det. God- 
ing.) 
Papilio rutulus Bdr.— West Fork, July. A common Transition spe- 
cies. Dr. Holland received the lepidoptera collected on the Gila, but 
has not yet worked them over. 
Yuccaborus sp. — Mr. Schwarz, who received the Gila coleoptera, tells 
me that the collection contained a species of Yuccaborus , the well known 
and rather rare large weevil which bores the trunks of Yuccas. It may 
be mentioned here that a species of Yuccaborus was found extremely 
abundant in July, 1895, half way between Brownsville, Texas, and the 
coast, in trunks of what is probably Yucca treculeana. Mr. Wickham and 
I took several hundred specimens in a couple of hours work at old and 
decaying trunks. The species will be determined, if possible, and will 
appear in a separate paper on the coleopterous fauna of the lower Rio 
Grande. 
Trichodectes sp. — Numbers of a very small parasite, with little doubt 
belonging to this genus, were taken on the hairs of scrotum and ad- 
jacent belly parts of a white-tailed deer ( Cariacus virginianus), shot on 
the West Fork about a mile below the falls, July 11. The specimens 
were sent recently to Professor Osborn, who has not yet reported upon 
them. The species may be T. parallelus Osborn n. sp., of Bull. No. 5, 
new series, Div. Entom. IJ. S. Dept. Agriculture (1896), pp. 240-241. 
No locality is given for T. parallelus , but the specimens were from the 
Cornell University collection and probably from the eastern United 
States.

Diptera.- — A paper by the writer will appear soon in the Journal 
N. Y. Ent. Soc., on a part of the diptera collected in the lower Rio 
Grande region, near Brownsville. One or more papers will follow, com- 
pleting the determinations of the diptera collected there by the writer. 
The species so far determined are as follows. Those not otherwise 
noted are Brownsville, and this applies throughout this section both 
with insects and plants. 
1. Simulium tamaulipen&e Towns, n. sp. — Reynosa, Tamaulipas. 
May 10. 
2. Tabanus atratus Fab. — April 16 and July 11. A Carolinian and 
Austroriparian species.
