case was that of double parasitism only. Whatever its nature, it 

 seems worthy of record but it is not unique for egg parasites. The 

 eulophid was seemingly Nesomyia cimbicis Brues, male, but the ab- 

 dominal petiole was very long and the parapsidal furrows apparently 

 complete or nearly, at least slender grooved lines. Its antennae were 

 in fragments and at the time I could not give the specimen enough 

 attention to insure its identity. The locality was Milwaukee, Wis., 

 June 30, 1911. It is worth recording, in this connection, that as many 

 as thirty or more individuals of the trichogrammatid came to maturity 

 in some of the isolated eggs of the Cimbex. A. A. GIRAULT. 



RHYNCHITES BICOLOR. This beetle is common in New Mexico and 

 Colorado, often damaging roses. When at Woods Hole, Mass., last 

 July, I found it equally common there, but somewhow the beetles did 

 not look right, so I brought some home for comparisons. It appears 

 that the Colorado insect, as compared with that from Woods Hole, is 

 distinctly smaller, of a lighter shade of red, with the elytra less coarsely 

 sculptured, and without the rows of evident coarse punctures. Also, 

 I find the head entirely black, whereas it is largely red in the Woods 

 Hole insect. I consulted Professor H. F. Wickham about this and he 

 kindly informed me of Le Conte's three "races," of which a from Ore- 

 gon and California, is probably the same as my Colorado insect. As 

 Professor Wickham knows of no available name, and T have found 

 none, I propose to call the Colorado insect Rhynchites bicolor wick- 

 hami, taking as the type one from Boulder, Colorado, collected by my- 

 self on rose in June. It is surely not more than a subspecies or race, 

 but I think valid as such. T. D. A. COCKERELL. Boulder, Colorado. 



SPHAERIDIUM SCARABAEOIDES. This beetle has reached Colorado ; I 

 took one on the University campus at Boulder. October, 1911. Blatch- 

 ley, in his Coleoptera of Indiana, says there are no striae on the elytra, 

 but in my specimen there are weak widely spaced striae. Professor 

 Wickham has kindly examined his material (from Canada, Rhode 

 Island, Illinois and Iowa) and finds the same striae, more distinct in 

 some than in others. T. D. A. COCKERELL, Boulder. Colorado. 



YELLOW APHID-INFESTING SPECIES OF APHELINUS DALMAN. Apropos 

 of yellow species of Aphelinus Dalman which infest aphids, I have 

 happened upon several instances in addition to the one recently pub- 

 lished by me (The Entomologist, London, 1911, p. 178), and think it 

 desirable that they be recorded. Mr. J. J. Davis sent me the material 

 in both instances. This was several years ago and only recently did 

 I have occasion to examine it. In some vials of alcoholic material- 

 aphid parasites I found two which contained a female specimen each 

 of a yellow Aphelinus together with the host aphid, the latter in each 

 instance bearing the characteristic exit-hole made by the parasite. The 

 specimens, however, were found to be in too bad condition for specific
