California. Cab. LeConte. 



Although bearing a general resemblance to the obscurus group 

 of eastern species, punctulatus differs remarkably from all of them 

 in its fine and much shorter pubescence. The type specimen is a 

 male, and is in a poor state of preservation, the pronotura being- 

 broken and crushed so that it is somewhat distorted in outline; the 

 above measurements have made allowance for this as far as possible. 

 The posterior legs are entirely wanting in the type. It is distin- 

 guishable from infuscatus by its broader form, relatively shorter 

 prothorax and longer elytra, shorter, stouter antennte and short 

 pubescence. 



The antennae are quite robust, unusually compact and cylindrical, 

 with the third joint just visibly longer than the fourth and both 

 of these much longer than joints five to eleven, which are equal in 

 length, the fifth about one-half longer than wide, the tenth nearly 

 two and one-half times as long as wide. 



6 H. melsheimeri n. sp. — Oblong-elongate, parallel, moderately con- 

 vex, piceous-black above, the entire under surface, legs and antennae paler, 

 rufo-ferruginous ; surface polished ; pubescence nearly as in obscurus. Head 

 rather coarsely, deeply, sparsely punctate, the eyes moderate, separated by 

 slightly more than their own width ; antenn?e short, stout, filiform, not more 

 than one-third as long as the body, the last three joints rapidly shorter, joints 

 three to nine equal in length, the intermediate almost parallel, twice as long 

 as wide. Prothorax three-fourths wider than long, the apex broadly arcuate, 

 continuous in curvature around the apical angles, the sides becoming parallel 

 and feebly arcuate almost through basal two-thirds ; basal angles right, not 

 rounded ; base transverse, with a short rounded median lobe ; disk obsoletely 

 impressed only along the middle toward base, finely, sparsely punctate, the 

 punctures round, perforate and separated by about three times their own 

 diameters. Eli/tra nearly four times as long as the prothorax and equal to it 

 in width, rather gradually, acutely pointed in apical third ; sides parallel and 

 nearly straight ; disk with feebly impressed series of fine, not very close-set and 

 inconspicuous punctures, the intervals minutely, sparsely punctate. Abdomen 

 finely, sparsely punctate. Legs slender ; basal joint of the hind tarsi nearly 

 one-half longer than the remainder, slightly arcuate. Length 7.3 mm. ; width 

 2.7 mm. 



Michigan. 



The unique specimen before me is immediately distinguishable 

 from any other in this section by its narrower, more parallel form, 

 and unusually short, rather stout, but filiform antennge, with nearly 

 parallel-sided joints. The sex of the type cannot be definitely deter- 

 mined without dissection.
