THE CANADIAN ENTOMOLOGIST 389 



Genus Bolbonota Am. & Serv. — Fowler's name aureosericea 

 preoccupied in this genus by aureosericea Stal, and for the former 

 I propose the name dubiosa. 



Genus Gypona Germ. — Gypona bimaculata Woodworth, 1887, 

 is preoccupied by Gypona bimaculata Spangberg, 1878, for the 

 former I propose the name woodworthi. 



Genus Euscelis Brulle. — Genus Athysanus Burm., 1838, type 

 argentatus Fabr., is scarcely separable from Phrynomorphus Curtis, 

 1833, type lineolatus Brulle. It seems, however, that both must 

 fall before Euscelis Brulle, 1832, type lineolatus Brulle. I have not 

 been able personally to examine Brulle's work, nor can I learn that 

 there is a copy in this crjntry, but he seems to have established 

 his genus for lineolatus, and as his genus has recently been recog- 

 nized by Dr. Horvath, it is evidently a valid genus, I recognize the 

 following subgenera: Athysanus Burm., type argentatus Fabr., 

 Euscelis Brulle, type lineolatus (= Conosanus Osb. and Ball), 

 Conomellus Osb. and Ball, type comma Van D. and Stirellus Osb., 

 and Ball, types bicolor Van D. 



NOTES ON SCIAPUS, WITH DESCRIPTIONS OF THREE 



NEW SPECIES. 



BY M. C. VAN DUZEE, BUFFALO, N. Y. 



Sciapus forcipatus Aid. 



Three males from Guatemala differ from Prof. Aldrich's 

 description in having the knob of the halters, lamellae of the hypo- 

 pygium, and hind tibiae yellow; and in having the wings marked 

 with the usual two cross bands, although these bands are not very 

 dark or well defined. The two long bristles at the tip of the 

 abdomen seem to be composed of two or more fine hairs so closely 

 twisted together as to appear as one, in one specimen these hairs 

 are partly separated ; the middle tibiae have two long bristles, one 

 at the middle and one at apical fourth; the middle tarsi in one 

 specimen have two rather long bristles, and several smaller ones 

 on the first joint; all the femora haye long white hairs below, the 

 middle pair have also the black bristles mentioned by Aldrich. 



I feel quite certain that these differences are not of specific 

 value; in fact, hardly sufficient to warrant separating it as a variety.
