A NEW GENUS IN THE CCELIXIN^E. 



BY E S. G. TITUS, URBANA, ILLINOIS. 



Chrysopheon, new genus. 



General shape and appearance of an Epeolns ; labrum very long, 

 rounded transversely, labial palpi 4-jointed, first joint longest, third and 

 fourth subequal ; maxillary palpi 2-jointed, second joint longest and 

 tapering, maxillae long, sickle-shaped and convoluted ; scutellum with 

 two short slightly-incurved spines, postscutellum produced medially into 

 a short, sharp, upturned tooth ; marginal cell rounded, not attaining the 

 costa, second sub-marginal cell longer than first, narrowed above ; 

 receiving both recurrent nervures, claws bifid, inner tooth shortest, no 

 pulvilli ; abdomen convex, densely pubescent and banded, last segment 

 of female bare, narrowed slightly and emarginate a very little at tip. 



Differs from Dioxys, Lepel., by second sub-marginal cell longer than 

 first, and by first joint of labial palpi being longer than second ; from 

 Hoplopasites, Ashm., by the colour of the abdomen as well as other charac- 

 ters; from Biastes, Panzer, by shape of abdomen and by palpal characters. 

 Chrysopheon aurifiuscus, new species. 



$ . — Black ; pubescence golden-brown ; head closely, confluently 

 punctured, clypeus coarsely, closely punctured with an elevated smooth 

 carina on its anterior edge ; labrum narrowed near base and truncate at 

 anterior end, confluently punctured, except at base, where it is longitudinally 

 striate, striae separate ; mandibles black, bidentate with outside groove ; 

 face with rather long hair, occiput and cheeks with shorter hair; antennas 

 black ; base of metathorax with a row of regular pits, much as in some 

 Colletes; pubescence of dorsum of metathorax short; on pleura, scutellum 

 and sides of metathorax longer, denser; wings clouded with a few hyaline 

 spots; tegulre reddish testaceous, hairy, punctured, shining; stigma 

 black ; legs with sparse glittering golden-brown pubescence, tarsi reddish ; 

 first four dorsal segments of the abdomen with dense short pubescence, 

 on apical margins heavier and forming distinct hair-bands ; fifth 

 segment with a narrow apical band, sixth segment bare, narrowed 

 very slightly towards the tip, longer than wide and slightly emarginate at 

 tip ; first five ventral segments with strongly visible hair-bands, that on 

 first narrower than others and all five segments sparsely pubescent with 

 short hair ; last segment smooth, rounded at tip, and shorter than the 

 last dorsal segment ; abdomen with close medium-sized punctures ; 

 ventrally the punctures are larger and more separate. Length 12 mm. 



Habitat. — Colorado. Described from two females taken on Horse- 

 tooth Mt., near Ft. Collins, altitude 7,500 ft., June 14, 1S99, on Monarda 

 citriodora and Chrysop villosus. 



The types are in the collection of the Colo. Agr'l College. 



Prof. Cockerell suggested to me that perhaps this was near Melecta 

 mucida, Cress., and that that species might belong to the same genus. 

 The type of M. mucida is in Acad. Nat. Sc. of Philadelphia. Mr. 

 Vierick writes me from there that the mouth parts are entirely concealed.
