contraction of the pectoral canal, the sliape of the mesosternal 

 receptacle, with the rostrum and antenna? are suggestive of affinity 

 with Mclanierius hut these are decidedly negatived hy the almost 

 entire ahsence of the metasternal episterna; the general shape with 

 many of the features are not unlike Hyhomorphus, hut the tihioe 

 are different and the sides are regularly rounded. On the whole 

 I helieve it to he allied to Salens, although the pectoral canal and 

 mesosternal receptacle are strongly at variance with the same 

 features in that genus. The apex of the rostrum rests just beyond 

 the mesosternum, the receptacle being excavated so as to allow it 

 to pass, but the canal is not distinctly terminated.

Blackish-brown, elytra and tarsi paler, antennae still paler. Elytra 

 feebly clothed with small depressed clusters of yellowish setae, 

 similar setae on the legs; elsewhere nude or almost so. 



Head with moderately dense but shallow punctures. Rostrum as 

 long as prothorax; punctures behind antennae in feeble grooves, 

 between and in front of antennae rather sparsely punctate. Funicle 

 with the first joint slightly longer than second, third moderately 

 long, sixth and seventh transverse. Prothorax largely but not 

 suddenly narrowed in front, much wider than long; punctures not 

 very large but dense and regular; with a very feeble median carina. 

 Elytra scarcely longer than wide, at base very little wider than 

 prothorax, widest before middle, base widely and regularly emar- 

 ginate ; striate-punctate, punctures not very large ; interstices 

 regular near base, about the middle becoming tuberculate and 

 irregular, themselves densely punctate. Flanks of metasternum with 

 large shallow punctures. Abdomen with irregular rows of very 

 large, regular, circular punctures or foveae on the two basal 

 segments, third and fourth each with a row of small and feeble 

 punctures, apical segment densely punctate. Legs densely punctate; 

 tibiae dentate beneath. Length 4 1/2 mill.

Each elytron has three distinct and several less distinct tubercular 

 elevations, the first is on the third interstice at its middle, the 

 second is on the fifth before it, and the third is on the seventh at 

 the basal third, the three forming an oblique series behind which 

 the interstices become very irregular; the fourth and sixth inter-
