from above) by at least six times their own diameter. Antenna short, 

 11 -segmented, with a few long and short, erect hairs intermixed ; third 

 segment subequal in length to fourth. 



'Pronotum quadrate, widest near apex, broadly depressed along an- 

 terior margin, with a narrow, longitudinal line on basal two-thirds ; 

 sides rounded near apical angles, obliquely narrowed posteriorly, 

 coarsely, densely punctate on disk, coarsely, densely granulose on 

 deflexed sides, rather densely clothed with moderately long, semierect, 

 yellowish hairs, with a few long, erect, yellowish hairs intermixed. 



Elytra at base distinctly wider than pronotum at apex, strongly 

 obliquely declivous posteriorly; sides parallel, broadly conjointly 

 rounded at apices; surface coarsely, sparsely, irregularly punctate at 

 base and along sutural margins on basal half, nearly impunctate pos- 

 teriorly, with a number of short, transverse, parallel plicae on each 

 side, nearly glabrous on apical declivity, but sparsely clothed with 

 short, recumbent, yellowish hairs at sides; apical declivity with sutural 

 margins elevated and each with a strongly elevated, marginal carina, 

 extending nearly full length of declivity, the tip midway between 

 lateral and sutural margins when viewed from above. 



Body beneath densely clothed with long, recumbent and semierect, 

 yellowish hairs, densely, rather finely punctate except on abdomen, 

 where it is very finely, confluently punctate ; arcuate spine at apex of 

 anterior tibia extending nearly to middle of second tarsal segment. 



Female. — Differs from the male in having the front of head uni- 

 formly convex and not flattened at middle, the eyes separated on the 

 front by about four times their own diameter, the pronotum more 

 vaguely depressed along the anterior margin and the surface densely. 

 confluently punctate or granulose on the disk, the elytra uniformly 

 finely, densely granulose, punctate, or rugose, and rather densely 

 clothed with short and long, erect, yellowish hairs, which are more 

 erect on the apical declivity. The arcuate spine at the apex of anterior 

 tibia about as long as the first tarsal segment. 



Length 7.5-15 mm., width 2-5 mm.

 locality (F. H. Chittenden, C. V. Riley and G. W. Belfrage). 



Gorham (1883) recorded this species from Cordova and Peras, 

 Mexico. 



Hosts.— This species has been reared from fig, cotton, and huisache 

 ( Acacia farnesiana (Linnaeus) Willdenow) stems and from the dead 

 limbs of Royal Poinciana in thp Brownsville. Tex., region. 



LeConte (1874) described plicatus from a single male and obliqwus 

 from a single female, both collected by G. W. Belfrage at an unre- 

 corded locality in Texas, ^'orham (1883), recognizing obliquus as 

 the female of plicatus, placed it as a synonym of plicatus.
