356 Coleopterological Notices, V. 



rately transverse, rounded; infralateral carina obsolete, feebly trace- 

 able very near the base. Eyes rudimentary, consisting of five or 

 six coarse facets in a cluster behind the mandibles. Antennas rather 

 short, moderately incrassate ; outer joints subsimilar, strongly trans- 

 verse; second cylindrical, as long as the next two and about as 

 thick. Mentum large, very slightly wider than long, trapezoidal, 

 the sides feebly sinuate ; apex rather more than one-half as wide as 

 the base and evenly sinuate in circular arc throughout the width. 

 Ligula not distinct in the type. Maxillary palpi normal, the third 

 joint longer than the second. Prothorax narrowed toward base, 

 the hypomera scarcely inflexed beyond the vertical, large, evanes- 

 cent far behind the apex. Elytra very short. Abdomen long, par- 

 allel ; first five segments equally impressed at base; fifth longer 

 than the fourth ; sixth distinct, a little narrower than the fifth but 

 as long as the fourth. Middle coxae contiguous, the mesosternal 

 process short, triangular, acute, extending barely to the middle. 

 Metasternal side-pieces rapidly widening behind. Legs very short, 

 sparsely hairy, the tibise not at all spinulose ; tarsi very short, 

 stout, the posterior three-fifths as long as the tibiae, with the first 

 joint very slightly longer than the second ; ungues very small, 

 slender, moderately arcuate. 



A."brevipes n. sp. — Slender, pale rufo-testaceous throughout, except the 

 abdomen above and beneath, which is piceous-black with the apex pale ; 

 integuments dull and minutely, strongly reticulate, the abdomen less strongly 

 so and more shining ; anterior parts finely, indistinctly punctate, the abdomen 

 minutely, not densely but more distinctly so ; pubescence distinct, rather long 

 and moderately dense. Head convex, ovalo-conoidal, a little longer than wide, 

 rather longer than the prothorax and fully as wide or a little wider ; antennae 

 nearly one-half longer than the head. Prothorax very slightly wider than long, 

 widest at the apical angles, the sides thence moderately convergent and nearly 

 straight to the basal angles, which are obtuse and slightly blunt ; apex broadly 

 evenly and rather strongly arcuate, distinctly wider than the base ; disk 

 broadly flattened toward the middle. Elytra three-fourths as long as the pro- 

 thorax, and, at apex, not at all wider ; sides convergent and scarcely arcuate 

 from apex to base. Abdomen as wide as the elytra, parallel, one-half longer 

 than the anterior parts ; sides straight ; border moderate, equal ; surface 

 transversely and feebly convex. Length 1.7 mm. ; width 0.3 mm. 



Alaska (Ft. Wrangel). Mr. Wickham. 



I have seen only a single specimen, probably a male, the sixth 

 ventral plate being broadly, very obtusely lobed behind.
