106 The West American Sctent7st. 
40. Eurycreon chortalis grote, not so common. 
41. Crambus luteolellus var. ulce. Ckll; the type of C. ulce was 
sent to Prof. Fernald, who referred it to luteolellus. I have not 
had access to the description of C. luteolellus, but Prof. Fernald 
gives duplicatus, grote and zeellus, Fernald, as synonyms also, 
and so far as one can tell from the entirely insufficient descriptions 
published of these they differ from C.ulce. I have therefore 
compromised matters by quoting ulce as a variety. 
42. Crambus sericinellus, Zeller, near Swift Creek. 
43: Alucita hexadactyla, L., very common. 
44. Lophoderus persicana, near Short Creek. 
45. Carpocapsa pomonella, L.,larva in an imported apple at 
West Cliff. 
46. Psecadia semilugens, Zell., common. 
47 Psecadia dicostrigella var. subccerulea, Walsm, near 
Short Creek. 
~ 48. Laverna definitella, Zell., near Swift Creek. 
II—DIPTERA. 
The following list is, of course, the merest fraction of what is 
to be found, but the difficulty of naming Diptera has hindered 
the preparation of any list worthy of thename. We hope to take 
the matter up to better purpose sometime in the future. For 
identifications of Diptera we are indebted to Prof. C. V. Riley 
and Mr. L. O. Howard. 
1. Cecidomyia salicis-strobildides, O. S., galls abundant on 
willow at West Cliff, many Hymenoptera as well as cecids reared 
from them. 
2. Cecidomyia bigeloviz, n. sp., a small species, about four 
mill. expanse, reared from wooly Trypetid galls on Bigelovia. 
Probably undescribed, but description deferred until further com- 
parisons with described species have been made. 
3. Lucilia cesar, L., not very common. 
4. Musca domestica, L., very abundant. 
5. Scriptotricha culta, common, breeds in flower-heads of 
thistles- 
6. Melanostoma ccerulescens, Williston, near Swift Creek. 
7. Eristalis hirtus, Loew, near Swift creek. 
8. Microdon globosus, a fly, presumed to be this, bred from 
pupa found in nest of Formica integra, nyl., at West Cliff. 
g. Dejeania vexatrix, O. S., one specimen. 
10. Gonia frontosa var. ater, Ckll., thorax and abdomen 
almost entirely black; near Swift Creek. 
11. Gonia exul. Williston, West Cliff. 
T. D..A... Cockerell.
