58 MEMOIRS ON THE COLEOPTERA. 



Easily identifiable by its black shining integuments and rather 

 sparsely punctured elytra. 



Echidnoglossa morigera n. sp. Large and rather stout, strongly 

 shining, deep black throughout, the first two abdominal segments scarcely 

 visibly picescent; vestiture fine, very short, dusky-cinereous and not 

 conspicuous; head apparently somewhat longer than wide, broadly and 

 parabolically rounded behind the eyes, the punctures fine and well 

 separated, almost wanting on the front, which is feebly impressed trans- 

 versely between the eyes as usual; antennae missing in the type; pro- 

 thorax short, not at all longer than wide, fully as wide as the head, finely, 

 rather loosely punctate, widest at or just behind the middle, the sides 

 thence strongly converging and straight to the apex, feebly converging 

 and subsinuate to the base; elytra large, but little shorter than wide, 

 of the usual parallel form with apically rounding sides, three-fourths 

 wider and nearly one-half longer than the prothorax, the punctures 

 moderately large and deep, separated by slightly more than their own 

 diameters; abdomen much dilated and as wide as the elytra posteriorly, 

 at base three-fifths as wide as the latter, the fine punctures rather strong 

 and numerous; legs blackish, the tarsi pale. Length 3.2 mm.; width 

 0.75 mm. Utah (Provo), Wickham. 



Easily known by its large size, deep black shining surface, short 

 hexagonal prothorax, strong but separated elytral punctures and 

 broad subapical part of the abdomen. 



Echidnoglossa clavicauda n. sp. Rather stout, shining, piceous-black, 

 the prothorax and basal part of the abdomen barely at all paler, the 

 femora blackish, the tibiae piceous, the tarsi pale; pubescence rather 

 short, not conspicuous; head as wide as long, almost semicircular behind 

 the eyes, the antennae very long, dark, gradually distinctly incrassate, 

 the second joint as long as the first, slightly longer and thicker than the 

 third, the fourth still slightly shorter, outer joints almost longer than 

 wide, the last rather longer than the two preceding; prothorax well 

 developed, about as wide as the head, not longer than wide, strongly 

 narrowed anteriorly from about the middle, finely but strongly, rather 

 closely and evenly punctate throughout; elytra subquadrate, coarsely, 

 closely punctate, three-fourths wider and two-fifths longer than the pro- 

 thorax, much impressed behind the scutellum as usual; abdomen rela- 

 tively very much dilated but not as wide as the elytra posteriorly, at 

 base but little more than half as wide as the elytra. Length 3.1 mm.; 

 width 0.7 mm. California (Soda Springs, Anderson Valley, Men- 

 docino Co.). 



Allied somewhat closely to valida but not so large, with rather 

 less incrassate antennae, more strongly narrowed basal part of the 

 abdomen and more slender legs; as usual throughout, the elytral 

 punctures become much smaller and sparser posteriorly.
