2. Oncideres Satyrus, n. sp. 
O. cylindricus, fulvo-brunneus ; elytris guttis albis paucis sparsis, 
basi tuberculis nigris ; antemiis validis ; thorace basi valde con- 
stricto. Long. 10-12 lin. <S $. 
Head in the much narrower than the thorax, in the $ as 
wide as the widest part of the thorax, with broad plane front, 
colour tawny brown, a black stripe below each eye. Antennae 
about the length of the body in the female, a little longer in the 
male, with the apical joint twice the length of the preceding ; 
they are robust in both sexes, but the four basal joints are 
thicker in the ^ than in the $ ; colour black. Thorax with 
transverse depressions; a conical tubercle on each side, and 
much constricted behind the tubercle ; brownish tawny, with a 
fine, black, central, transverse line. Elytra cylindrical, brownish 
tawny, sprinkled with a small number of minute white spots; 
base and shoulders with a few polished rounded tubercles ; rest 
of surface impunctate, smooth. Body beneath and legs thickly 
clothed with tawny pile ; sides of breast chalky white. 
Para. Closely allied to O. vomicosus, Germar (Ins. Nov. 482), 
but diflfering greatly in the maculation of the elytra, the spots 
being small, few in number, and all distinct from each other. 
3. Oncideres fulvus, n. sp. 
O. oblongo-subcyliiidricus ; thorace postice baud constricto, guttis 
nigris quinque discoidalibus in linea transversa dispositis, tuber- 
culo parvo laterali ; elytris modice elongatis, valde convexis, leevi- 
bus, guttis parvis albis sparsis, prope basin tuberculis utrinque 
circa duodecim nigris. Long. 1 1 lin. $ . 
Closely resembles O. Satyrus ; but the body is proportionately 
shorter and broader in the female than in the corresponding sex 
of that species ; the thorax is shorter, and shows no constriction 
near the base ; the elytra are uniformly convex and impunctate, 
and there are very few tubercles near the base, only two con- 
spicuous ones on each side of the scutellum, and a small number 
under each shoulder. The colour is entirely ochreous tawny, 
with the exception of five small spots placed in a transverse row 
across the thorax, the black elytral tubercles and a small number 
of widely separated, but tolerably uniformly distributed, white 
specks over the elytra. The antennse are somewhat darker, and 
and there is a very distinct oblong chalky spot on each side of 
the breast.
