586 CRYPTOPHAGIDA. 
PLATOBERUS, gen. nov. 
Coxe omnes distantes; tarsi lati, breviusculi, subtus lobati. Prothorax latus, angulis anterioribus 
discretis. 
The insects forming this genus are allied to Loberus, from which they are readily 
distinguished by the above-mentioned characters. The form of the prothorax is 
peculiar, and gives the members of the genus a distinctive facies. The lateral 
depression near the base of the elytra is also a good character, though it may be seen 
in a less striking form in certain species of Loberus. 
I have not seen any specimens of Platoberus from other regions; but as our four 
species all come from Panama, the occurrence of the genus in South America is more 
than probable. 
1. Platoberus latus, sp. n. (Tab. XVIII. fig. 10.) 
Latus, subdepressus, rufescens, nitidus ; antennis clava magna nigra, prothorace disco plus minusve infuscato ; 
elytris post humeros late impressis et explanatis, seriatim subtiliter punctatis et breviter parce setosis, 
interstitiis setis raris, longioribus, erectis armatis. 
Long. 3-33 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
This insect is readily distinguished by the broad lateral cavity of the elytra and by 
the peculiar setosity: this consists of regular series of fine curvate hairs springing from 
the fine punctures of the elytra, and a few longer erect hairs rising from the broad 
interstices. The front angles of the thorax project a little forwards. On the under 
surface the metasternum is furnished with distinct, elongate, free coxal lines; but on 
the first ventral segment there are no coxal lines, the very flat coxal margin forming 
merely a short, angular prolongation. Iam not able to distinguish the sexes. There 
is not much variation in the series of about forty specimens received. 
2. Platoberus rotundus, sp. n. 
Latus, rufo-testaceus, nitidus; elytris post humeros impressis, seriatim subtiliter punctatis, setosis, interstitiis 
setis longioribus haud conspicuis. 
Long. 27 millim. 
Hab. Panama, Bugaba (Champion). 
Readily distinguished from P. latus by the short rotund elytra, the serial punctures 
on which are more closely placed and the pubescence longer. The distortion of the 
sides of the elytra is less, the prothorax is straight in front, and the front angles project 
a little laterally; the head and thorax are also narrower than in P. latus. The coxal 
margins of the first ventral segment are not angulate. ‘T'wo specimens.
