668 Mr. G. C. Champion’s Notes on 
prothorax, long, subparallel; coarsely, confusedly punctate on the 
disc, the punctures becoming seriately arranged towards the sides. 
Length 61, breadth 3 mm. (2?) 
Hab. W. Mexico, Acapulco (Hége). 
One specimen. Larger and broader than the N.-American 
T. gibbosa, Say; the prothorax relatively wider, dis- 
tinctly sinuate at the sides posteriorly, and without tufts 
of matted hairs on the dorsal hump; the elytra interruptedly 
lineate with brown, and each with a conspicuous tuft 
of blackish-brown hairs on the disc below the base in a 
line with the common, V-shaped, sutural mark, and a 
common transverse series of six smaller tufts preceding 
the large, sharply-defined, whitish apical patch. It is 
just possible that this insect may prove to be referable to 
the unidentified Mexican 7’. imperator, Cast., but the 
latter has the base of the elytra differently marked, to 
judge from the brief description. 
Trichodesma discigera, n. sp. 
Elongate, convex; piceous, the antennae, mouth-parts, and tarsi 
obscure ferruginous; densely clothed with pale brown and whitish 
pubescence abundantly intermixed with very long, erect, pallid 
hairs; the elytra with a sharply-defined, large, common, rounded 
(somewhat saddle-shaped), sparsely fusco-pubescent space before 
the middle, followed by a broad, common, arcuate, irregular brown 
fascia (extending to the outer margin and enclosing a short oblique 
whitish streak on each elytron near the suture and several blackish 
spots), and also bearing several dense tufts of erect blackish hairs— 
one very large, oblong, placed at about one-third from the base, 
and just within the outer limit of the discoidal patch, and three 
in a transverse series at about the apical third, the inner one 
rather large, the others small—the humeri also with a dark spot. 
Head densely punctulate and subgranulate; antennae moderately 
long, joints 4-8 small, subequal, the dilated joints 9-11 elongate, 
9 about as long as 5-8 united. Prothorax transverse, the sides 
strongly arcuate before the middle and sinuously, obliquely con- 
verging behind, the hind angles just traceable; finely, conspicuously 
granulate; the dorsal hump large, angular, and compressed, without 
definite matted tufts of hair, apparently lineate, due to the parting 
of the pubescence. Elytra much wider than the prothorax, long, 
subparallel; with irregular rows of very coarse, deep punctures, 
the larger tufts of hair arising from the third interstice. 
Length 53, breadth 2? mm. (2?)
