A few adults of Sarcophaga species, many of Sepsis violacea Meigen, 

 and a few of another Muscid dipteron, were reared from the droppings 

 infested with cornicina. 



The determinations of the Diptera were made by Mr. Coquillett, 

 and of the hymenopteron by Mr. Crawford, both of the U. S. National 

 Museum, through the kindness of Dr. L. O. Howard. 



ON NORTH AMERICAN AND SOME CUBAN 

 COPELATUS. 



By Charles Schaeffer, 

 Brooklyn, N. Y. 



Copelatus caslatipennis Aube, Spec. Gen., VI, p. 382. 



I have taken a specimen in Brownsville, Texas, and Mr. Roberts 

 has a number of specimens from Sanford, Jacksonville and Taylor 

 County, Florida, which are referrable to this species. It is near glyph- 

 icus, but dull, not shining, generally smaller and narrower; apices of 

 elytra feebly attenuate and subacute ; thorax in both sexes with very 

 fine scratches over the entire surface ; the front tibiae at base distinctly 

 curved on the upper edge, and the front and middle tarsi of the male 

 much more broadly dilated than in glyphicus ; the head, thorax, a 

 basal fascia, and generally the sides of elytra, ferruginous, the thorax 

 sometimes darker at middle ; base of elytra in both sexes with more or 

 less distinct, short scratches. 



Copelatus impressicollis Sharp, Trans. Roy. Dub. Soc. n. s., II, p. 589. 



I took a few specimens in the Huachuca Mts., Arizona, which I 

 refer to this species. It is a larger and darker insect than glyphicus, 

 with an equal number of discal striae on each elytron, but slightly shorter 

 at base and apex ; front tibiae of the male are simple and the tarsi 

 much dilated ; the thorax has a few scratches at sides in the male, these 

 extend over nearly the entire surface in the female. One female 

 has on the elytral intervals a number of short, impressed, longitudinal 

 lines and between the ninth and tenth striae and the tenth and the 

 submarginal striae an additional, but abbreviated stria of somewhat 

 irregular outline. The other female shows scarcely any impressed lines 

 on the disk, but has them at sides ; the additional striae are also present 

 but much shorter and still more irregular.
