ClCINDELID/E AND CARABID/E 155 



everywhere obsolete, only the sutural and marginal series of punc- 

 tures evident, the humeral carina short, strongly elevated and the 

 length of male and female 19 to 20 mm. From Icevipennis Lee., 

 which it seems to resemble in size, it differs in its deep black colora- 

 tion, without trace of violaceous tint, in the less transverse pro- 

 thorax, which is said to be "basi capito triplo latior" in that species, 

 shorter humeral carina, which is described as a third as long as the 

 elytra in Ifsvipennis and more obsolete series of punctures. The 

 type of Icsmpennis was taken on the Platte River and the dimensions 

 of the type are 17.5 by 7.7 mm. 



*Liodicaelus suffusus n. sp. Much smaller and less convex than the 

 preceding, black, with distinct though sometimes partial violaceous 

 bloom, alutaceous to strongly shining; head nearly similar, half as wide 

 as the prothorax to a little less; antennae (cf ) only moderately slender but 

 filiform, nearly as long as the head and prothorax, the outer joints rapidly 

 abbreviated; prothorax shorter, a third wider than long, moderately con- 

 vex, formed nearly as in the preceding but with thinner, though strongly 

 reflexed, side margins, the median stria fine but distinct, subentire, the 

 transverse impressions both obsolete or nearly so, the sublateral curved 

 impressions of the preceding barely distinct to wholly obsolete; elytra 

 nearly as in the preceding but less elongate and much less convex, barely 

 two-fifths longer than wide, with series of punctures very distinct through- 

 out the width, but, as usual, a little stronger suturally, the punctures 

 small though deep, differing remarkably in form, some circular and others 

 elongate; humeral carina rather strong and acute, short, obsolete near 

 basal fourth or fifth. Length (cf 9 ) 13.5-15.8 mm.; width 5.6-6.3 mm.

 Abundant. 



The nine examples at hand indicate a species which, by reason 

 of the violaceous bloom, sometimes very strong throughout the 

 upper surface, is remindful of l&vicollis Lee., but it is very much 

 smaller, with less transverse prothorax and very much shorter 

 humeral carina; the under surface is deep and shining black, the 

 sternal side-pieces faintly violaceous. In a few examples and by 

 very oblique light, the surface of the third and fifth elytral intervals 

 may be seen to be extremely faintly convex, a reversion to a common 

 character in Diccdus. Lcevipennis Lec.,flohri Bates, evanescens and 

 suffusus are the only species referable to Liodiccelus, so far as now 

 known.
