- PENTARIA, 259 
Six examples. Duller and more densely pubescent than the North-American 
P. trifasciata, Melsh. (a specimen of which has been communicated by Dr. Horn), 
the antennz longer, the black markings of the elytra more extended—the median 
fascia broadly connected along the suture with the basal one, but the latter does not 
(as in P. trifasciata) reach the humeri. If black is taken as the ground-colour, 
the elytra may be described as having an oblique stripe extending from the shoulders 
downwards (curving upwards near the suture in some specimens), a narrow fascia 
beyond the middle, and sometimes the extreme apex, brownish-yellow. 
7. Pentaria quadriguttata. (Tab. XI. figg. 3; 4, var.) 
Moderately elongate ; the head testaceous or reddish-testaceous; the prothorax in great part piceous, the base 
and apex of the same colour as the head (the light colour often forming a large spot on either side of the 
middle at the base); the elytra piceous or fuscous, each with a broad flavo-testaceous fascia before and 
another beyond the middle (the former sometimes connected with the opposite one at the suture, and 
extending along the side to the base, the latter not reaching the suture), the suture a little lighter in 
colour; the upper surface subopaque, finely pubescent, the prothorax and elytra finely transversely 
strigose. Head moderately large, the eyes black; antennew short (scarcely reaching the base of the 
prothorax when the head is extended), thickening outwardly, joints 9 and 10 subtransverse, 1-4 
testaceous, 5-11 piceous or brown; palpi testaceous; prothorax about one third broader than long 
feebly bisinuate at the base, slightly rounded at the sides, the hind angles rectangular; beneath piceo- 
testaceous, the metasternum and venter darker; legs testaceous, moderately slender; sixth ventral 
segment visible. 
Length 23-3} millim. (¢ @.) 
Hab. Guatemata, Capetillo, Guatemala city, San Gerénimo (Champion); Panama, 
Volcan de Chiriqui (Champion). 
Var. The piceous colour on the prothorax reduced to a well-defined transverse median band ; the testaceous 
elytral fasciee much larger and longer, but not reaching the suture, the dark basal mark in the form of a 
large triangular scutellar patch, this being lighter in colour than the median and apical bands. (@.) 
Hab. Mexico, Cuernavaca (H. H. Smith). 
Eight examples of the typical form and one of the variety. The much shorter 
antenne, more shining surface, partly infuscate thorax, different elytral markings, &c., 
distinguish this species at a glance from P. trisignata and P. trifasciata. The insect 
varies in the amount of the dark and light colour, but two very distinct transverse 
or oblong spots are always visible on each elytron, and the thorax is more or less 
infuscate across the middle; the pubescence partakes of the colour of the surface from 
which it arises. P. guadriguttata has much the facies of a banded Addera. 
8. Pentaria unifasciata. (Tab. XI. fig. 5.) 
Comparatively short ; testaceous, the elytra each with a rather broad black transverse median band which does 
not reach either the suture or the lateral margin; the upper surface slightly shining, finely pubescent, the 
prothorax and elytra very finely transversely strigose. Head moderately large, the eyes black; antenne 
testaceous, slightly darker towards the apex, short (not nearly reaching the base of the prothorax when 
the head is extended), thickening outwardly, joints 9 and 10 transverse; prothorax about one half broader
