convex and produced at apex. In fidiginosiis the pygofers of 

 the female are unusually slender while in ovatus they are very 

 short and abruptly narrowed at apex. 



Color dark ferruginous brown without markings, a little 

 lighter on the head and base of the metopidium, sutures of the 

 face and the median line black. Legs pallid. Elytra with a 

 fuscous cloud beyond the middle. 



This species is very close to what I here determine as mu- 

 ticus Fabr. and much resembles a dark discolored specimen of 

 that species in which the oblique line is obsolete, but the char- 

 acters of the face seem to be sufficiently distinct. This speci- 

 men is without locality. 



4. Cyrtolobus muticus Fabricius. PI. 2, fig. 16. 



Form nearly of arcuatus Emmons as figured by him. Pro- 

 notum well elevated ; dorsal outline sinuated both before and 

 behind the crest which is regularly arcuated above from a point 

 over the humeri almost to the tip of the abdomen ; surface 

 coarsely punctured. Color pale yellowish inclined to ferrugin- 

 ous or at times almost fuscous brown; oblique anterior vitta 

 distinct, bordered posteriorly by an equal band of much darker 

 color; before this vitta the ground color is paler with some 

 black points along the median carina; posteriorly the median 

 dorsal spot is rarely indicated but there is at times a pale line 

 on the carina in the posterior sinus: apex of the pronotum long 

 and straight, almost or quite attaining the tip of the elytra. In 

 dark examples the metopidium is more or less mottled, and in 

 pale specimens an arcuated brown vitta is sometimes indicated 

 above the humeri. Face roughly punctured, uneven at base; 

 clypeus prominent, convex, but little exceeding the cheeks. 

 Elytra subhyaline, in fuscous examples quite strongly enfumed, 

 apex not at all darker. Beneath concolorous; oviduct blackish 

 at base. Length 7mm. 



I have taken this species at Atlanta, Ga. ; Mr. W. T. Davis 

 has sent me specimens from Staten Island; Mr. Z. P. Metcalf 

 specimens from Ohio; Prof. John Barlow from Rhode Island, 

 and in the Cornell University collection are others from Ithaca, 

 N. Y., and from North Carolina. This species may readily be 

 recognized by the double (dark and light) oblique vitta and 

 the long pronotum. It does not agree entirely with the descrip
