350 MEMOIRS ON THE COLEOPTERA 



Desmiphora intricata n. sp. Subcylindric, piceous-black, very densely 

 clothed with brown prostrate hairs, sprinkled with a few cinereous in 

 color; head flat between the antennae, the latter (9 ) four-fifths as long 

 as the body, compact, very densely, coarsely pubescent and with long 

 flying hairs in addition, the pubescence brown, sprinkled with cinereous, 

 the latter color alone at the bases of the joints; scape only twice as long 

 as wide; prothorax as long as wide; base and apex equal, the latter the 

 more arcuate, the lateral spines strong, rather abruptly formed at the 

 middle; surface convex, coarsely, rather sparsely punctate, with two 

 nearly straight parallel-sided oblique white vittae from the base at the 

 sides, nearly to the apex more medially, where each is sinuate within; also 

 with an elongate flat polished glabrous central spot and an eye-like 

 blackish-pubescent spot, margined with white, at each side anteriorly; 

 also, at the middle of the apex, a large tuft of long erect white hairs, 

 extending and diminishing posteriorly, ending at the central glabrous 

 spot; elytra a little wider than the prothorax, twice as long as wide, 

 rounded at the apices, having a discal carina at inner third, just outside 

 of which and at apical fourth, there is an elongate rough glabrous tumor 

 surrounded by long erect fulvous hairs and joined with the suture and 

 external margin by a very fine line of short white hairs, which bears a 

 small fascicle of long white hairs near the suture and another at outer 

 third, where there is a strong arcuation of the line; also with two small 

 discal fascicles of stoutbrown hairs near the base; region near the scutellum 

 flattened, coarsely punctate, subglabrous and bounded behind by fine 

 oblique lines meeting on the suture before basal third, where each bears 

 a small fascicle of long white hairs; under surface with an eye-like white- 

 margined spot at each side of each abdominal segment; legs densely 

 pubescent and with long hairs; fifth ventral (9) elongate, strongly 

 rounded at tip; last dorsal appearing behind the elytra, rounded, 

 densely nigro-pubescent, with a central spot of white. Length ( 9 ) 

 10.0 mm.; width 3.5 mm. Texas (Brownsville). 



It is difficult to convey any useful idea of this beetle without a 

 good deal of verbiage; the above description will probably enable 

 one to compare it with other described Mexican species. 



Tribe ONCIDERINI. 

 Lochmseocles Bates. 



It seems to the writer that the difference in habitus between this 

 subgenus, erected by Bates to receive certain large and heavily 

 built species, in which the male antennal tubercles are produced 

 in slender spiniform processes, and the smaller, much more slender 

 species, without cephalic modification in the male, constituting 

 Oncideres proper, are sufficient to give Lochmaocles full generic 

 value. In addition to these differential features, it should be stated
