Coleopterological Notices, III. 81 



Texas ; Kansas ; New Jersey. 



The elytral intervals are slightly more sparsely punctured in the 

 male than in the female. Punctulata may be distinguished at once 

 from socia by the pronotal punctuation, the punctures being widely 

 dispersed except toward base and narrowly along the middle in the 

 latter, and the size of socia is much greater. In punctulata the 

 eyes are not absolutely contiguous in the male, but are separated 

 by a narrow setose isthmus; in oculatifrons they are contiguous 

 along a fine straight double line which is however also setigerous. 



Jj, oculatifrons n. sp. — Elongate-oval, moderately convex, black 

 throughout ; anterior tarsi ferruginous ; antennae piceous, gradually paler 

 toward apex ; lustre polished throughout, the pubescence rather long, fine, 

 moderately sparse, piceo-fulvous in color and not at all conspicuous. Head 

 rather coarsely, sparsely punctate ; eyes very large but extremely unequal in 

 the sexes ; antennae long, slender and filiform, one-half as long as the body. 

 Prothorax from one-half to two-thirds wider than long, subquadrate, the sides 

 almost parallel and straight in basal two-thirds, then strongly, evenly rounded 

 to the apex, the latter truncate, three fourths as wide as the base, which is 

 transverse, the sinuations broad and very strong ; basal angles right, not 

 blunt ; disk coarsely, evenly and somewhat closely punctate throughout, 

 obsoletely impressed along the middle ; punctures generally separated by two 

 to three times their width ; basal foveae distinct. Elytra four times as long as 

 the prothorax and about one-fifth wider, gradually acute behiud from about 

 the middle, the sides parallel and nearly straight toward base ; humeri very 

 narrowly exposed ; disk rather finely but strongly, evenly striate, the strial 

 punctures moderately coarse, deep, perforate and rather approximate ; inter- 

 vals nearly flat, finely punctate, sparsely so in the male, decidedly densely so 

 in the female. Abdomen rather finely but strongly, sparsely punctate, not 

 noticeably more densely so along the middle in the male. Legs long and slen- 

 der ; basal joint of the posterior tarsi fully equal in length to the remainder. 



Male. — More slender than the female, the eyes extremely large, contiguous 

 along a fine straight line which is nearly as long as the entire epistoma ; 

 antennae with the third joint two-thirds as long as the fourth ; tarsal char- 

 acters as in punctulata. 



Female. — Eyes separated by slightly more than one-half their width ; anten- 

 nal and tarsal characters as in punctulata. 



Length % 9.5, $ 10.2-10.8 mm. ; width % 3.2, $ 3.8-4.0 mm.

This species, while allied to punctulata, may be easily distin- 

 guished by its larger size, more parallel and subquadrate prothorax, 

 intense black color, the larger eyes of the male and the decidedly 

 denser elytral punctuation especially of the female. The difference 

 in the density of elytral punctuation of the male and female is 

 extremely pronounced.
