54 MEMOIRS ON THE COLEOPTERA 



2 Body deep black in color, the under surface and legs feebly rufescent; 

 antennae and oral organs testaceous; head fully two-thirds as wide 

 as the prothorax, the latter more than one-half wider than long, 

 fully as wide as the elytra, the sides rounded anteriorly, moderately 

 converging and broadly sinuate basally; surface steeply declivous 

 at the sides to the distinct marginal gutter, which is rufescent from 

 diaphaneity, slightly explanate postero-laterally, the foveae large, 

 shallow and very vague; basal parts with some fine faint punctulation 

 and rugosity in addition to the coarse punctures; elytra oblong, 

 nearly a third longer than wide, parallel, very broadly rounded at 

 apex and with dentiform humeral angles, the striae very coarse and 

 deep, the scutellar finer, long, generally joining the first; intervals 

 feebly convex, each with a regular and widely spaced medial series of 

 very coarse setigerous punctures; marginal interval with scattered 

 smaller punctures. Length (c? 9 ) 7.8-11.7 mm. ; width 3.4-4.6 mm. 

 Colorado, New Mexico and Arizona. Abundant setosa Lee. 



Body smaller and very much shorter, piceous in color, shining; head and 

 antennae nearly as in the preceding; prothorax relatively smaller, 

 not more than four-fifths as wide as the elytra, nearly similar in 

 outline but with smoother surface between the very coarse punctures; 

 elytra very much shorter, not longer than wide, the sides more 

 abruptly oblique and straight near the base, the sculpture and setae 

 similar, except that the punctures of the marginal interval are in a 

 single series; legs pale flavo-testaceous. Length 8.0 mm.; width 

 3.7 mm. A single example of undetermined sex and without label 

 in the Levette collection brevipennis n. sp. 



3 Piceous in color, shining; prothorax slightly wider than the head, 

 almost one-half shorter than wide, subcordate, posteriorly narrowed, 

 the sides rounded, setigerous, .subsinuate posteriorly, the hind 

 angles right, foveate laterally at base; elytra convex, the striae deep, 

 the intervals 1-3-5-7-9 with sparse setigerous punctures, arranged 

 almost uniseriately; antennae, labrum, palpi and legs rufo-testaceous. 

 Length 10.5 mm. Arkansas. [Cratognathus alternatus Lee.]. 



alternata Lee. 



The description of alternata, which I have not seen, is taken from 

 the original; it seems to be extremely rare. There may be some 

 doubt as to the correctness of the generic assignment of this species. 



Nothopus Lee. 



Notwithstanding the evidently different facies of this genus when 

 compared with the preceding, there is a very close bond of affinity 

 and they form a notably isolated group of the Harpalinse, having a 

 massive compact body and very coarse scattered setigerous punc- 

 tuation of the upper surface. The special characters relating to the 

 anterior tibiae constitute the only important structural difference
