2^4 TWR CANADIAN ENTOMOLOGIST. 



half their length beyond the apex of the plates, ligulate in form and 

 curved downward and outward at apex ; pygofers rounded at apex, 

 almost equalling the plates, the small anal aperature placed superiorly. 



New York ; Connecticut. Described from three males. One taken 

 at Portage Falls, N. Y., May 30th, 1888. The other two specimens were 

 taken by me in Connecticut in the spring of 1883. One of these was 

 swept from weeds and bushes on the hills about Northford, June 26th ; 

 the other, a very deeply coloured example, I found in a grove on Prospect 

 St. in New Haven, June 4th. The long extruded styles of the males will 

 at once distinguish this from any other of our described species of 

 Athysanus. 



5. Athysanus instabilis, ;/. sp. 



More elongated than most of our species of this genus. Black, 

 irrorated and finely marked with pale yellow. Elytra pale, the areoles 

 edged with fuscous. Length, 4-4^2 mm. 



Head obtusely pointed before ; vertex about y$ longer on the middle 

 than next the eye, passage to the front well rounded, base with a few im- 

 punctured areas. Ocelli large, fulvous, distant from the eyes ; temples 

 broad ; front convex, the sutures arquated at the antennae and incurved 

 at apex ; clypeus feebly narrowed towards its slightly rounded apex ; 

 cheeks rather narrow, but feebly angled, not exceeding the clypeus. Pro- 

 notum rather long, with the sides long and carinated, latero-posterior 

 edges straight, angles prominent, obtuse, surface strongly punctured or 

 shagreened. Elytra long, with the appendix well developed. Valve of 

 the male short, obtuse at apex ; plates forming an equilateral triangle, 

 fulvous clouded with dusky, their edges nearly straight, fringed with pale 

 bristles. Last ventral segment of the female slightly produced and 

 rounded on the middle, feebly arquated either side within the short sub- 

 acute lateral angles ; pygofers rather small, slightly exceeded by the 

 oviduct. 



Colour black. Base of the vertex, outer edge of the cheeks, and mar- 

 gins of the eyes slenderly yellow. Two transverse spots on the disc 

 of the vertex near its base, two lines anterior to these, one or two dots 

 near each eye, an angled slender line on the apex including a dot behind, 

 a dot on the temples, about six arcs, a basal spot and a longitudinal line 

 on the front, the latter expanded against the base of the clypeus, and
