unique among our species. These characters will usually separate 

 velutinus from the other closely related southwestern species (see p. 100). 

 0. velutinus ranges from central Texas through Arizona but it is 

 quite rare in collections. Most of the specimens bearing collecting 

 data simply state "collected at light." It apparently has a re- 

 stricted habitat, probably only in Neotoma albigula Hartley nests, a 

 habitat in which it was first collected by L. J. Bottimer. It was 

 taken at black light and in wood rat nests on the lower slopes of the 

 Chisos Mountains (Howden, 1960, p. 460).

Male majors. — Length 6.8 to 8.1 mm, width 4.0 to 4.4 mm. Head 

 and pronotum usually bright shining green, occasionally becoming 

 violaceous; elytra usually with brownish-yellow basal band and 

 apical spots, medially greenish black, extreme base of elytra and 

 sutural interval blackish. The black area may almost completely 

 cover the elytra, leaving, in extreme cases, only three or four small 

 brownish spots near the basal edge of the elytra, the apical spots 

 being entirely absent. Pygidium usually brownish yellow basally, 

 black apically, but varying from almost completely brownish to 

 entirely black. Clypeus anteriorly sharply reflexed, the anterior 

 margin forming a median flattened perpendicular horn, laterally 

 abruptly rounded, the sides almost parallel and giving the clypeus 

 a rectangular appearance. Disc of clypeus smooth and shining, 

 with a few coarse scattered punctures; laterally becoming rugosely 

 punctate; clypeal carina sometimes semiobsolete, but more often 

 appearing as a fine, sharp, transverse ridge running completely across 

 the posterior clypeal margin; behind the clypeal carina the head 

 medially slightly convex, with scattered coarse setigerous punctures; 



« O. concinnus has been Incorrectly credited to the author Castelnau because, as pointed out by Qrensted 

 (1952), "Laporte" was the author's name and "Comte de Casteinau" merely his title. In his own writings, 

 Laporte used the abbreviation "Lap." (See Laporte, 1840, 149, "Trochalm Lap.")
