272 GEO. H. HORN, M. D. 



moderately dense puuctnation, slightly shining, clothed with very fine and short 

 pubescence; scutellum closely punctured, Elytra scarcely wider than the tho- 

 rax, the punctuation dense, fine and equally disposed, each puncture with a short 

 hair; sutural costa distinct, the discal costfe obliterated, submarginal costa dis- 

 tinct in its apical half. Pygidium shining, not closely punctate. Metasternum 

 finely not closely punctate, the hair not long. Abdomen more shining than the 

 upper surface, the punctuation fine, not close, pubescence short and easily abraded, 

 last ventral segment with coarse ])unctures 9- Legs somewhat red, the tibise 

 aud tarsi usually darker. Tooth of claws long, acute and median. Last joint 

 of maxillary palpi moderately long and cylindrical. Length .60 — .65 inch ; 

 15 — 16 mm. 



Male. — Unknown . 



Female. — Antenna! club shorter than the funicuhis. Spurs of 

 hind tibiae long and slender. 



Of this species but two specimens have been examined, both fe- 

 males, differing only in size. 



Of all the species of Lachnosterna this has the finest punctuation, 

 and on the elytra so closely placed as to produce the opacity of the 

 surface. In form it resembles quereus. 



Occurs in Texas, region unknown. 



58. li. crenulata Frohl. — Oblong, very little wider posteriorly, brown, 

 feebly shining, surface clothed with short yellowish recumbent hair, often with 

 erect hairs intermixed. Clypeusemarginate, the border reflexed, surface coarsely 

 and closely punctate with short erect hairs, front more densely punctured with 

 longer hairs. Thorax with lateral margin coarsely serrate, the median smooth 

 line interrupted, surface very coarsely and closely punctate, less densely at sides 

 aud base, with moderately long erect yellowish hairs. Elytra equally pun(rtured, 

 the punctures much finer than on the thorax, moderately closely placed, sutural 

 costa feeble, discal costte usually indistinct, submarginal costa well marked and 

 entire, surface with short recumbent pubescence, often with erect hairs inter- 

 mixed. Pygidium with coarse moderately dense punctures and short erect hair. 

 Metasternum moderately closely punctured at the sides, smoother at middle, the 

 hair rather long but sparse. Abdomen less densely but more coarsely punctured 

 and with short sparse pubescence. Claws with a strong median tooth, alike in 

 both sexes. Length .65 — .80 inch ; 17 — 20 mm. 



Male. — Antennal club as long as the funiculus. Penultimate 

 ventral segment vaguely concave at middle. 



Female. — Club shorter than the funiculus. Posterior legs stouter 

 than in the male. 



Variations. — In by far the larger number of specimens exam- 

 ined the pubescence of the elytra is uniform in character, being 

 short and recumbent. This is the form assumed by the specimens 

 from Massachusetts to North Carolina, but as the species is found a 

 hundred or more miles west the pubescence is coarser, and a tendency
