Microgoes n. gen. 



The type of this proposed new genus is Goes oculatus of LeConte. 

 It differs from Goes in the small size of the body, different type of 

 elytral ornamentation, smaller and still more slender tarsi and, 

 more especially, in the very long and filiform antennae, which are 

 often much more than twice as long as the body. These differential 

 characters are far more important than those separating the well 

 known tropical genera Hammoderus, Tceniotes and Deliathis; for, 

 in addition to those given above, the eyes are very much reduced in 

 size in Microgoes. The two species in my cabinet may be separated 

 as follows: 



Black throughout the body, legs and antennae, the elytra sometimes feebly 

 picescent, the entire aspect cinereous however, because of the rather 

 close and even, though finely and vermicularly disintegrated, clothing 

 of short cinereous hairs, each elytron with a rounded eye-like spot 

 of black or blackish hairs at three-fifths from the base on the median 

 line; pubescence beneath and on the legs dense, uniform and cine- 

 reous-white; antennae (9 ) very slender, not quite twice as long as 

 the body, the basal joint rather slender, nearly three times as long 

 as wide but not as long as the fourth joint, all clothed with de- 

 cumbent ashy hairs, not densely placed and not herissate beneath; 

 prothorax extremely densely, confusedly and rather finely punctato- 

 rugose and opaque, the spine acute; scutellum semicircular, densely 

 pubescent; elytra moderately elongate, much more than twice as 

 long as wide, narrowing arcuately behind in nearly apical third, the 

 apices rounded; elytral punctures moderately coarse, deep, close-set 

 and asperulate. Length (9) 9.7-11.0 mm.; width 3.0-3.4 mm. 

 New York oculatus Lee. 



Black, the general aspect more intensely black than in the preceding, 

 owing to the much less dense cinereous vestiture, which rather 

 sparsely but irregularly speckles the elytra, the eye-like spots of the 

 latter in the same position but very much less sharply defined; 

 general form and sculpture similar but with the elytra much less 

 elongate, being not evidently more than twice as long as wide in 

 either sex; antennae similarly very slender and filiform and even 

 longer, being nearly two and one-half times as long as the body in 

 both sexes, semi-nude throughout, the ashy decumbent hairs being 

 very much sparser than in oculatus; whitish hairs_ of the under 

 surface, and especially of the legs, much less dense; male with the 

 fifth ventral but little longer than the fourth, very broadly truncate, 

 this segment in the female being fully one-half longer than the fourth 

 and more narrowly truncate at tip. Length (cf 9 ) 8.7-10.3 mm.; 

 width 2.8-3.0 mm. Pennsylvania (Westmoreland Co.), Schmitt. 



tenuicornis n. sp. 



I have seen no account of the food habits of these species, which 

 do not seem to be very common in collections.
