their own length from the base, the tempora less prominent, long, arcu- 

 ate and but feebly converging to the base; antennae a little shorter and 

 more gradually thicker distally to the tip, the third joint barely shorter 

 but thinner and more constricted basally than the second, fourth slightly 

 wider than long, fifth rather abruptly wider, transverse, tenth almost 

 twice as wide as long, the last but little longer than wide, very obtuse, 

 as long as the two preceding; prothorax nearly as in the preceding 

 throughout, though relatively smaller and with the basal angles obtuse 

 and not or scarcely at all prominent externally; elytra large, nearly as 

 long as wide, with sensibly diverging sides, at base more than a fourth 

 wider, the suture one-half longer, than the prothorax; abdomen narrow, 

 parallel, with very feebly arcuate sides, much narrower than the elytra, 

 the four impressions distinct but gradually diminishing as usual, the 

 fifth tergite one-half longer than the fourth. Length 1.8 mm.; width 

 0.4 mm. Idaho (Coeur d'Alene), Wickham. 



This species is also represented before me by a single female ; 

 it is allied to wickhami but differs in its much smaller size, smaller 

 eyes, relatively larger elytra, narrower abdomen and somewhat 

 in coloration and antennal structure. 



Homalota humilis n. sp. Slender, subparallel, depressed, distinctly 

 shining, piceous, the elytra slightly paler, the head and abdomen black, 

 the latter not paler at apex, the legs pale piceous; punctures of the head, 

 rather small but distinct, of the pronotum fine and indistinct, of the elytra 

 fine, distinct and asperulate, rather close, of the abdomen very fine and 

 remote, closer basally; pubescence short; head as long as wide, not quite 

 as wide as the prothorax, the eyes well developed, rather prominent, at a 

 little more than their own length from the base, the tempora slightly less 

 prominent, parallel for a long distance, then rounded to the base; front 

 broadly, feebly concave; antennae a little longer than the head and 

 prothorax, piceous-brown throughout, the third joint slightly shorter 

 and more basally constricted than the second, both much shorter than 

 the first, fourth slightly wider than long, four to six increasing rather 

 rapidly, six to the tip very gradually but very moderately thicker, the 

 tenth fully one-half wider than long, the last subcylindric, very obtuse 

 at tip and as long as the two preceding; prothorax a fourth wider than 

 long, widest well before the middle, the sides broadly rounded, converging 

 and straight basally, the angles obtuse and rather blunt, not at all 

 prominent, the surface broadly impressed medially behind the centre; 

 elytra slightly shorter than wide, with feebly diverging sides, at base a 

 fourth wider, the suture nearly one-half longer, than the prothorax; 

 abdomen parallel, much narrower than the elytra, the fourth impression 

 much finer and feebler than the others, the fifth tergite longer than the 

 fourth, the sixth ( 9 ) broadly rounded at apex, becoming sinuate medially, 

 its surface asperate. Length 1.9 mm.; width 0.4 mm. New York 

 (Catskill Mts.).
