6 — Body much broader, oblong-oval, more .sparsely pubescent, the sub-erect hairs 

 longer, abundant and conspicuous ; elytra piceous, variegated with paler and 

 with three transverse fasciae of pale hairs, the second usually divided into two 

 spots on each elytron, and the third broadly interrupted at the suture, also with a 

 spot of paler pubescence at each side of the scutellum. Length 3.4 mm. ; width 1.8 

 mm . Arizona varicolor Juyiie 



Ferplcxa of Jayne, I have not seen, but it is evidently allied to 

 hyturoides, differing in the relatively shorter last joint of the antennal 

 club. Byfuroides was considered by Dr. Jayne as the female of horni, 

 but this is not the case, as I have both male and female of that species 

 as well as the allied uteana. 



JVove/s/s differs from Lanoriis in antennal and hypomeral structure, 

 and from Telopes in the structure and armature of the legs in addition. 



Dearthrus Lee. 



This genus is allied to Attay;enus but differs in having the meso- 

 sternum completely divided by a narrow shallow sulcus, in the 

 9-jointed antennas and in the shorter, less inwardly postero-extended 

 metacoxal lamina. The single species may be defined as follows from 

 the male : — 



Narrowly oblong-oval, moderately convex, piceous-black in color ; prothora.x twice 

 as wide as long, strongly narrowed from base to apex, with the sides evenly and 

 feebly arcuate, the base broadly and feebly lobed, feebly oblique and sinuate 

 laterally, the surface rather strongly but not densely punctate, with a fine exca- 

 vated median line not attaining base or apex ; elytra three-fourths longerthan 

 wide, rather strongly but not very closely punctured; under surface black, the 

 legs rufo-piceous ; pubescence throughout dark in color, uniform, short and not 

 con.spicuous ; antennae as figured under Atlagemts. Length 2.4 mm.; width 1. 15 

 mm. Indiana longulus Lee. 



Apparently rare ; I have before me only a single specimen in rather 

 poor state of preservation. 



Perimegatoma Horn. 



In this exclusively western genus, which belongs to an important 

 section of the Attagenini differing from those above considered in the 

 elongate basal joint of the tarsi, the antennal club is 3 -jointed, with 

 its two basal joints transverse and the last elongate, though to a less 

 degree than in Attagenus. The prosternum is strongly deflexed at 

 tip to form a protection to the mouth in repose, as in most of the other
