Hymenoptera. — The bees and other aculeate hymenoptera have been 
worked oyer by Professor Cockerell, and are as follows: 
1. Triscolia sp. — Gila Hot Springs, elevation about 6000 feet, July 
20. The species belongs to a gronp of Scolia found in Lower California 
and Texas. 
2. Sphex ichneumonea Linn. — West Pork, July. A common U. S. 
species, taken commonly at Santa Fe by Cockerell. 
3. Sphex nearcticus Kohl. — Head of Bast Fork, July 22. “Common 
in the Mesilla Valley.” (Ckll.) 
4. Priononyx foveolatus Tasch. — West Fork, July (det. Fox). “Very 
abundant in the Gila collection. Hot known elsewhere in H. M.” (Ckll.) 
This must therefore be a Transition species of somewhat restricted 
range. 
5. Priononyx sp. apparently atrata St. Farg. — West Fork, July. “P. 
airata is common at Santa Fe.” (Ckll.) 
6. Tachytes sp. apparently spatulatus 9 — .Head of East Fork, July 22. 
“Can not be sure of determination without a $ . T. spatulatus occurs 
at Santa Fe.” (Ckll.) 
7. Philanthus albifrons Cress. $ . — Head of East Fork, July 22. This 
is the first record of this species from Hew Mexico. It is a Colorado 
species, doubtless Transition. 
8. Philanthus frontalis Cress. $ . — West Fork, July. “Occurs in 
the Mesilla Valley.” (Ckll.) 
9. Philanthus sp. af¥. flavifrons Cress. — West Fork, July. P. ftavi- 
frons is a Colorado species. 
10. Odynerus annulatus Say. — West Fork, July. “Common in Mesil- 
la Valley. Taken years ago by Lewis in northern H. M.” (Ckll.) 
11. Odynerus sp. aff. leucomelas Sauss. — West Fork, July. “Agrees 
with leucomelas, but the markings are yellow, not white. O. leucomelas 
occurs in the Mesilla Valley.” (Ckll.) Three other species of Odynerus 
were taken, but are not yet identified. 
12. Polistes sp. — Head of East Fork, July 22. This is a different spe- 
cies from P. aurifer, which is the common Hew Mexico and southwest- 
ern species. 
13. Vespa occidentalis Cress. — West Fork, July. A Hevada, Colorado, 
and Hew Mexico species. “I used to get it at 8000 feet in Custer County, 
Colorado.” (Ckll.) 
14. Colletes gilensis Ckll. n. sp. — West Fork, July 16. This is larger 
than any previous species of Colletes known from Hew Mexico. “Allied 
to northern and eastern types.” (Ckll.) 
15. Agapostemon texanus Cress. — West Fork, July. A Texas species. 
“Common in Mesilla Valley.” (Ckll.)
