75. Id. crinita Burm.— Oblong-ovalj distinctly broader behind, rufotestace- 

 ous, shining, head and thorax with moderately long erect hairs. Clypeus entire, 

 concave, the margin rather widely reflexed, coarsely not closely punctured, front 

 similarly punctured and with erect hairs. Thorax with entire margin, subcren- 

 ate posteriorly, disc with coarse punctures, evenly arranged over the entire sur- 

 face, moderately closely placed, each with a moderately long, erect, yellow hair. 

 Elj'tra with punctures distinctly coarser than on the thorax, evenly arranged 

 and more closely placed than their own diameters, surface without hair, the discal 

 costfe entirely ol)literated. Pygidium coarsely, sparsely punctured, shining. 

 Metasternum densely finely punctured, the hair long and yellow. Abdomen 

 shining, a few fine, sparse punctures at the sides, last two segments with coarser 

 puuctures. Last joint of maxillary palpi slender, fusiform, not impressed. 

 Claws variable in the sexes. Length .50 — .64 inch ; 13 — 16 mm. 



Male. — Club of anteuna? one and a half times the length of the 

 entire stem. Abdomen slightly impressed at middle, penultimate 

 ventral slightly rugose at middle. Last ventral with an acute me- 

 dian impi-'-ssion. Tarsal claws feebly arcuate, the tooth small and 

 slightly intraniedian. Pygidium broader than long. 



Female. — Antennal club very short. Tarsal claws more curved 

 and with a stronger tooth. Tarsi, especially the posterior, much 

 shorter than in the male. Pygidium as long as wide. 



Variations. — Nothing has been observed, except size. 



The small group in which this species is placed has but three 

 members, which are easily separated from each other. This one is 

 noteworthy in having no hair on the elytra and the antennal club of 

 male very long. 



This species has, until now, borne the name glabripennis Lee, but 

 I have no hesitation in restoring Burmeister's name, and am surprised 

 that a fact so evident should have escaped recognition for so long a 

 time. 



Occurs in Texas, extending into Mexico. 



76. L<. tristis Fab. — Oblong-elongate, slightly broader behind, sometimes 

 slightly oval, yellowish testaceous, sometimes slightly reddish, sparsely clothed 

 with short semi-erect hair on the elytra, with longer erect hair on the thorax 

 and at base of elytra. Clypeus entire, concave, coarsely sparsely punctured, not 

 prolonged at sides on the eyes, front more densely punctured and with erect 

 hair, not long. Thoracic margin entire, fimbriate with long hair, disc coarsely 

 and rather closely punctured, hair long, erect and yellow. Elytra evenly 

 punctured, the punctures closer than on the thorax, but not dense, pubes- 

 cence sparse, short, semi-erect, with longer hairs at the base, extending some- 

 what along the suture, discal and submarginal costfe entirely obliterated. 

 Pygidium coarsely and closely punctured with moderately long erect hairs. 

 Metasteruum densely finely punctured, the hair long, yellow and silken. Abdo- 

 men coarsely, usually moderately closely punctate, shining, the pubescence very
