6. Cratomorphus ovatus. (Tab. XI. fig. 18.) 
Late ovatus, nigro-plumbeus, parum nitidus; prothorace, pedibus basi elytrorumque margine infra medium 
flavescentibus ; thoracis disco prope basin rufo, linea mediana et ad marginem basalem vix infuscata, sutura 
tenuiter flava. Long. 15, lat. elytr. 8 millim. ¢. 
Mas. Segmento ventrali apicali medio paullo acuminato; pygidio truncato, margine apicali bisinuato, segmentis 
quinto et sexto macula transversa lucide flava. 
Hab. Panama, Volcan de Chiriqui 6000 feet (Champion). 
A single male, not very satisfactorily placed in this genus. The only structural 
point, however, in which it differs seems to be that the abdomen is wholly dark leaden 
black, with the exception of the two luminous spots. The genital or eighth segment is 
concealed, as usual in Cratomorphus. ‘The general appearance is that of Hyas, but the 
anal aperture is closed. The antenne are shown too long in the figure. 
7. Cratomorphus fasciatus. (Tab. XII. fig. 4.) 
Late ovatus, postice attenuatus, nigro-fuscus, vix nitidus; prothorace fasciaque obliqua in elytris et sutura 
antice tenuiter flavis; thorace subtiliter rugoso, macula basali picea opaca. Long. 15, lat. elytr. 84 
millim. ¢. 
Mas. Segmentis ventralibus quinto et sexto medio flavis, septimo (apicali) apice bisinuato(?); pygidio apice 
truncato, simplici. 
fab. Costa Rica (Van Patten). 
This is a very distinct species from any other known to me; but as there is only 
a single specimen, not in very good preservation, I cannot accurately define the apical 
ventral segment. It might almost be placed in Aspidosoma, but that the dorsal 
segments are acutely lobed at their external angles. It is of the pointed oval form of 
many Hyas; the antenne, however, are as short as in the last species, and the eyes are 
large. The fascia commences as a wide oblong spot reaching half across the elytra, 
and then continued obliquely to near the apex. 
ASPIDOSOMA (p. 53). 
The larva figured on Tab. XII. fig. 26 is probably that of a species of this genus.

Differs from A. daterale only in its uniform rusty-brown colour; the elytra are 
equally but not more attenuated behind. I do not think it will prove to be distinct;
