Having since received specimens from Guatemala which accord better, both as to 
colours and locality, with Thomson’s description of D. quadriscopulatus, it is necessary 
to describe the Nicaraguan insect as a different species. Besides its more variegated 
coloration, it differs in being more ovate and convex, and in the antenne being much 
longer in the male and the elytra more transversely truncated. 
4. Tetrasarus callistus. 
Latior, depressus, griseus, letissime variegatus ; fronte fulvescenti-fusca lateribus flavis ; occipite medio maculis 
duabus nigris extus utrinque macula flava marginatis; thorace grosse sparsim punctato, lateribus flavis 
nigro maculatis, dorso purpureo-fusco ; elytris subtrigonis, apice breviter transversim subsinuatim trun- 
catis angulis haud productis, dorso utrinque obsolete bicostatis, griseo et fulvo lineatis, maculis guttisque 
nigris inspersis, et fascia irregulari prope basin flava nigro marginata ; antennis nigris, articulis 3° et 4° 
griseo biannulatis, 5°-11™ basi griseis; pedibus nigris, femoribus tibiisque flavo annulatis; tarsis articulis 
1° et 4° griseis, 2°-3° nigris; corpore subtus griseo, fulvo maculato; mesosterno bituberculato.

Hab. Guatemata, Capetillo (Champion). 
Allied to 7. pictulus, but distinguished by its broader and more depressed form, and 
the ochreous-yellow sides of the thorax and elytral fascia, which latter consists of a 
large bilobed spot near each side, connected with the suture by a very flexuous yellow line. 
Mr. Champion has sent home only one example. 
5. Tetrasarus albescens. 
Oblongus, convexiusculus, niger, supra albo-tomentosus nigro-guttatus et plagiatus; antennis robustis, arti- 
culis basi cinereis, 2° apice dilatato, 3° sulcato, 8°-11™ (2?) abbreviatis intus dense breviter ciliatis ; 
thorace punctato, tuberibus dorsalibus minus elevatis nigro-lineatis ; elytris versus apicem paullo rotun- 
datis, apice recte breviter truncatis, supra vix conspicue carinatis sparsim grosse nigro-punctatis, plagis 
indefinitis utrinque 4 vel 5 atro-fuscis (una humerali, 2° discoidali ante medium, 3° laterali post medium, 4° 
et 5% parvis prope apicem); pedibus robustis, nigris, tibiis cinereo biannulatis; tarsis articulo 1° et 4° 
- cinereis.
