288 Annals of the Carnegie Museum. 



Melanophila aeneola Melsh. — Bred from hickory wood in June. 



Chrysobothris pusilla. — Only two specimens were obtained in Pitts- 

 burgh. 



Agrilus ruficollis and pusillus are abundant here. Tonjitatus is 

 not rare on hiclcory ; anxii/s and blanchardl are rare here in early 

 June. 



Lampyrid.e. 



Telephorus rotundicollis and flavipes are abundant in May and June. 



Eros humeralis and Plateros floralis Melsh, are, like most of this 

 group, rare about Jeannette. 



Photinus marginellus Lee. — This species has probably been con- 

 fused with scintillaus, the female of which has short elytra, and seems 

 to be a southern species ; the female of our local species has elytra 

 as in the male, which would indicate the species iiiari:;iiielliis, not 

 scintillaus. 



CtERID.^i. 



Opilus domesticus Kl. — -(3ne specimen of this handsome insect 

 occurred at Wilmerding. 



Trichodes nuttalli Kirby. — I have seen specimens taken in western 

 Pennsylvania, but never found one myself. No doubt it occurs here. 



Clerus ichneumonius Fab. — Some years ago I took four examples 

 of this fine species ; Mr. Ehrmann took quite a number of them at 

 Charleroi, Washington County, Pa. 



Ptinid.e. 



Trichodesma sp. ? — I find a species of this genus on hickory 

 trees which is quite different from gibbosa, the elytra being deeply 

 striate and punctate. It can be separated from gibbosa at a glance, 

 and there seems to be no variation, the male and female having the 

 same peculiarities. 



Trypopitys punctatus Lee. — One specimen occurred at Jeannette. 



Dinoderus porcatus and substriatus are found rarely in Westmore- 

 land County. A few specimens of b/rvis were found under the bark 

 of a dead tree which was standing. 



Several species of this family are as yet undetermined. 



ClOID.B. 



Cis chevrolatii and americanus are occasionally found here in 

 decayed fungi.
