clustered into four small tufts on the dorsal hump of the thorax and 
various fascicles on the elytra (giving the appearance of black spots), 
the whitish pubescence condensed into three oblique lines on each 
side of the thorax, some small spots or streaks on the disc of the 
elytra, and two, narrow, curved, transverse lines near the apex, 
the pale brownish hairs condensed into an indeterminate, common, 
post-scutellar patch. Eyes very large. Antennae with the three 
joints of the club very elongate, the apical joint much longer than 
the preceding. Thorax arcuato-explanate anteriorly, strongly 
sinuate at the sides behind; densely granulato-punctate, the dorsal 
hump very prominent, angulate as seen in profile. Elytra elongate, 
parallel, much wider than the thorax, conjointly rounded at the 
apex; with rows of coarse, closely placed, transverse punctures 
visible through the vestiture, the interstices narrow, faintly granu- 
late. 
Length 43, breadth 2;; mm. (? 3.) 
Hab. GuatTEeMALA, San Geronimo in Baja Vera Paz 
(Champion). 
One specimen. Very like 7. armata, but wanting the 
tooth at the sides of the thorax; the eyes larger; the elytra 
conjointly rounded at the tip, and with the markings 
differently arranged, the small scattered tufts of black 
setae giving a spotted appearance to their surface.

2, p. 200. 
Described from a single 2 from Vera Paz. A male was 
subsequently received from Atoyac, Mexico, and it proves 
to have very much longer antennae than the type. 
*Trichodesma scripta, n. sp. (Plate IV, fig. 7.) 
Oblong, nigro-piceous or black, the antennae, tarsi, and abdomen 
rufo-ferruginous, the femora and tibiae slightly infuscate ; variegated 
with black and cinereous decumbent pubescence, intermixed with 
very long light and dark hairs and black setae, the cinereous pubes- 
cence on the thorax confined to the sides and anterior portion and 
an oblong median vitta at the base (leaving a black horseshoe- 
shaped mark on the disc), and that on the elytra into a common 
quadrate patch at the base, extending outwards along the anterior 
margin, a common sharply-angulated rather broad median fascia, 
and a transverse patch at the apex, the black setae condensed into
