90 PROCEEDINGS OF THE NATIONAL MUSEUM vol.89 



Elytra finely, sparsely, and regularly punctate, with minute hair and 

 some much longer hair near base of scutellum. Pygidium convex, 

 pruinose at base, polished apically; densely, not coarsely punctate in 

 basal half, much less densely so in apical half, apex truncate. Ab- 

 domen flattened at middle, pruinose at sides and somewhat at middle; 

 segments finely, sparsely punctate at middle, fifth segment plane, 

 sparsely punctate, with several short and erect hairs apically; sixth 

 segment transversely impressed, with moderately dense marginal 

 rows of short hairs at base and apex. All claws pectiniate along a 

 double margin, the outer row of pectinations of outer front tarsal claw 

 with a large, acute subapical tooth. Hind tibia with one spur three- 

 fourths as long as the other and the longest rather broadly spatulate. 



Female. — Thorax a little more coarsely punctate. Antennal club 

 subequal to funicle; club testaceous, funicle castaneous. Pygidium 

 moderately convex, densely pruinose in basal half, highly shining in 

 apical portion, the latter usually convex (in some few specimens there 

 is a trace of a finely impressed longitudinal sulcus, but not nearly so 

 distinct as in the females of L. mucorea and L. pulcher, in which the 

 apical half of the disk is also flat); disk with moderately dense and 

 coarse punctures, with short suberect hairs. Abdomen evenly con- 

 vex, highly polished, and with fine, moderately dense punctures at 

 the center. Hind tibial spurs spatulate. Inner hind claw without a 

 larger intercalated tooth; all other claws serrate to subpectinate, with 

 a strong intercalated tooth. Otherwise similar to male. 



Length. — 14-16 mm. Width. — 6.5-8 mm. 



Types. — Holotype and allotype are from Hidalgo County, Tex., 

 collected by H. J. Reinhard on April 5, 1930, and are in the United 

 States National Museum (No. 53764). 



Paratypes: Males, 16; females, 8. Texas: Several, same data as 

 types; Weslaco, March 16 (Clark) [Reinhard]; Alice, June 12; Mer- 

 cedes, February (Urbahms) [Reinhard]. 



Remarks. — Externally rather similar in both sexes to L. mucorea but 

 quite dift'erent in the male genital organs; the females are quickly 

 differentiated by pygidial characters. Named for H. J. Reinhard, of 

 the Agricultural and Mechanical College, Texas, who has contributed 

 much valuable material, both for the present and foT other studies of 

 the author's.
