128 PHYTOPHAGA.——-SUPPLEMENT. 
and the elytra are almost equally closely punctured; while in the present insect the 
strie of the elytra are subgeminate and the interstices broad and with only a few 
punctures. The male of 8. maculicollis is unknown to me, but of 8. fatens we have 
examples of both sexes. In the variety the anterior portion of the thorax is only 
obscurely stained with piceous, and the elytra are without bands, the extreme apex of 
the latter being whitish and the margins very narrowly black, a small black spot being 
also placed on the shoulders. | 
17. Scolochrus quinque-maculatus. (Tab. XXXVIII. fig. 10.) 
Pale flavous, the antenne, the underside (partly), and the legs black or piceous; thorax minutely punctured, 
with two large black spots ; elytra finely punctate-striate, a subtriangular sutural spot at the middle, a 
small spot at the sides, and the lateral margins posteriorly, black. 
Length 2 lines. 
Head flavous, finely and closely punctured at its lower portion, the vertex more or less stained with fuscous ; 
antenne half the length of the body, the lower five joints obscure fulvous, the rest black; thorax nearly 
three times as broad as long, strongly narrowed in front, the surface remotely and finely punctured at the 
sides and still more sparingly so at the disc, testaceous, with a large anteriorly-pointed piceous spot on 
each side, the spot touching the base but not extending to the anterior margin, the sides with a shallow 
oblique depression ; scutellum pale piceous, finely punctured, its apex truncate ; elytra slightly narrowed 
posteriorly, the stric distinct and rather regular, those at the sides a little more irregularly placed, the 
surface bright flavous with a subtriangular sutural spot at the middle, the point of which extends upwards 
nearly to the base, and a small spot below the middle on the lateral margin, black; pygidium and the 
sides of the abdominal segments pale flavous, the rest of the underside and the legs black, the femora 
more or less stained with fulvous at the base. 
Hab. Panama, David in Chiriqui (Champion). 
Of this pretty and well-marked species fifteen specimens were obtained ; these show 
no perceptible variation. ‘The eyes in the male insect are, as usual, more approximate 
than in the female; the elytral spots, of which the sutural one is the largest, are placed 
transversely, the smaller and lateral one being rather lower down, and there is also a 
very small one (sometimes absent) on the shoulder. | 
18. Scolochrus yucatanus. (Tab. XX XVIII. fig. 11.) 
d. Black, a spot between the eyes, the base of the scutellum, the last abdominal segment, and the apex of the 
posterior femora whitish; thorax finely punctured; elytra finely and regularly punctate-striate, red, with 
a black triangular sutural spot. 
Q. Head and scutellum entirely black. 
Length 22-3 lines. 
Head black, nearly impunctate; the eyes rather closely approached, but separated by a distinct space; a 
quadrate spot between the antenne yellowish; labrum fulvous, with a black spot; antenne black, the 
basal joint at the apex and the second joint also flavous; thorax about two and a half times broader than 
long, strongly narrowed in front, the sides obsoletely angled at the middle, the surface entirely black, 
remotely and finely punctured on the disc, the sides more strongly and closely punctate and with 
an obsolete transverse oblique depression; scutellum black, the base flavous; elytra with regular and 
finely punctured strie, the interstices very minutely granulate, red, the apical and sutural margins very 
narrowly, and a triangularly-shaped acutely-pointed spot at the middle across the suture, black; below 
black, clothed with silky white pubescence, a spot between the posterior coxa, the last abdominal 
segment, and the lower margin of the four posterior femora and tibiw yellowish-white.
