13. Li. vivicllis n. sp. — Narrow, polished, pale flavo-testaceous, the ab- 

 domen fuscous; elytra in posterior two-thirds piceous or blackish; antenna; 

 black except toward base. Head fully as long as wide, minutely, very re- 

 motely punctate, rather strongly rounded behind, the temporal angles very 

 obtuse and scarcely distinguishable; eyes moderately large, ])rominent; an- 

 tenna' rather short and somewhat stout, longer than the head and prothorax, 

 tlie tenth joint slightly longer than wide. Prnthora.r distinctly narrower than 

 the head and longer than wide, minutely, remotely punctate throughout, the 

 anterior lobe slightly transverse, widest a little behind the middle, the collar 

 rather narrow but distinct; posterior lobe gradually dilated to the base, about 

 one-third of the total length; pubescence inconspicuous. Elytra four-fifths 

 longer than wide and twice as wide as the ijrothorax, quite distinctly dilated 

 behind the middle, moderately broadly suljtruncate at ai^ex; humeri only 

 moderately exposed at base; omoplates slightly prominent; transverse impres- 

 sion almost completely obsolete; punctures minute and sparse, becoming 

 notably stronger and closer in the basal pale area; pubescence tine and incon- 

 spicuous, coarser and cinereous but scarcely at all denser in basal third. Ab- 

 domen polished, sparsely .pubescent, the legs slender. Length '2.2 mm.; 

 width 0.65 mm. 



Arizona (Tu9son and Pinal Mts.). 



The four specimens before me are females and represent a well 

 defined, small and very delicate species, not closely allied to any 

 other here described. 



14. I^.bipartitll!>in. sp. — Subparallel, the elytra rather depressed, polished 

 throughout, pale llavo-testaceous, the abdomen except at base and elytra, ab- 

 ruptly in posterior three-fifths, blackish; antenna; gradually fuscous toward 

 apex. Head but very slightly wider than long, convex, minutely and re- 

 motely punctate, transversely rounded at base, the temporal angles well- 

 marked though obtusely rounded; eyes rather large and prominent; antenna? 

 moderately slender, fully one-half as long as the body, the outer joints just 

 visibly thicker, the tenth distinctly elongate. Prothoia.v large and thick, con- 

 vex, slightly narrower than the head and a little longer than wide, minutely, 

 evenly and not very sparsely punctate; anterior lobe somewhat transverse, 

 oval, large, Avidest ne<ir the middle, tlie posterior lobe rather short and wide, 

 parallel; lateral constriction not extending at all obliquely upon the disk. 

 Elytra three-fourths longer than wide, very nearly twice as wide as the pro- 

 thorax, the sides almost perfectly parallel and nearly straight; apex somewhat 

 abruptly and broadly truncate; omoplates broad and feeble; surface finely, 

 si)arsely punctate, the punctures but slightly more distinct and not closer 

 toward base, whore the pubescence is slightly more distinct especially along 

 the Hanks. Abdomen sparsely, rather coarsely pubescent, the legs slender. 

 Length 2.1 mm.; width 0.75 mm.
