toward the middle. Legs slender ; basal joint of the hind tarsi fully one-third 

 longer than the remainder. Length 6.2-7.5 mm. ; width 2.7-3.1 mm. 



Texas ; New York. 



The typical form above described is from Texas, the Long Island 

 specimen being quite similar, except that the pronotum is rather 

 more finely punctured and the elytral series not so strongly im- 

 pressed, tending to disappear laterally toward apex. It is singular 

 that in these species the elytral punctuation of the male is quite 

 distinctly sparser than that of the female, but the antennas seem to 

 be about equal in length in the two sexes. Still more striking 

 sexual differences in punctuation will be alluded to under discretus. 1 



This species is easily separated from the others of this section by 

 the characters given in the table. 



13 H. communis Lee. — New Spec. Col., 1866, p. 135. — Oblong-oval, 

 rather pale rufo-castaneous throughout, polished, the pubescence moderate in 

 length, coarse, pale, rather sparse. Head coarsely, sparsely punctate ; eyes 

 moderate, separated by slightly more than their own width ; antennae (male) 

 slender, filiform, two-fifths as long as the body, joints five to eleven equal in 

 length, very slightly obconical, distinctly more than twice as long as wide 

 and each a little shorter than the fourth, the latter about twice as long as the 

 third. Prothorax two-thirds wider than long, broadly, strongly arcuate at 

 apex, the sides feebly convergent from the base nearly to the apex and rather 

 strongly evenly arcuate ; basal angles scarcely more than right, not distinctly 

 blunt ; base transverse, the sinuations broad and rather feeble, disk scarcely 

 impressed, rather coarsely, sparsely punctate, the punctures separated by two 

 to three times their width. Elytra equal in width to the prothorax and nearly 

 three and one-half times as long, rather abruptly, obtusely ogival at apex, 

 the sides parallel and nearly straight ; disk with distinctly impressed series 

 of rather coarse deep punctures, which extend distinctly to the apex ; inter- 

 vals finely, very sparsely punctate. Abdomen finely but strongly, sparsely 

 punctate. Legs slender, the basal joint of the hind tarsi much longer than 

 the remainder. Length 5.3 mm. ; width 2.2 mm. 



North Carolina. 



The description is drawn from the male as I have not positively 

 identified the female. In this male type the last joint of the maxil- 

 lary palpi is rather large and elongate, but almost perfectly recti- 

 triangular, with the outer side subequal to the apex, and the elytral 

 series are distinct to the apex. 



This is the smallest species of the present group except humeralis, 

 and does not appear to be at all common. 



1 The sparser elytral punctuation of the male is also a common character 

 in Lobopoda.
