554 . CUCUJIDA. 
The punctuation of the head is not in the least rugose, and is finer than that of the 
thorax. The thorax is more slender than usual, and has the lateral denticles very 
evident. | 
This is apparently less rare in Mexico than most of the other species of the genus ; 
of the series of thirty-five specimens, thirty are Mexican, one is from Guatemala, and 
three from Nicaragua. 
9. Telephanus gracilicornis, sp.n. (Tab. XVII. fig. 18.) 
Depressus, testaceus, capite prothoraceque parce perobsolete punctatis, fere opacis, hoc gracili, lateribus 
evidenter denticulatis; elytris fortiter, regulariter, seriatim punctatis. 
Long. 43 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
This species is readily distinguished by the effaced sculpture of the head and 
pronotum and the slender antenne entirely of one colour. The head is rather 
strongly and abruptly constricted behind. The thorax is not much more than half as 
broad as the elytra; it is scarcely narrowed at all from the front to just behind the 
middle, whence it becomes evidently narrower to the base; the lateral denticles are 
quite distinct. The elytra bear very regular rows of large punctures, separated by 
narrow interstices, and continuing distinct to very near the tip: there are three or 
four small denticles on the lateral margin, near the base. The submental area on 
the underside of the head has no distinct punctuation, but an excessively minute 
sculpture. | 
Two specimens in a rather poor state of preservation. They bear a good deal of 
pubescence on the apical portions of the elytra; the anterior parts of the body are 
almost entirely abraded. 
10. Telephanus dromioides, sp.n. (Tab. XVII. fig. 19.) 
Depressus, parvus, testaceus; capite, prothorace, elytrorum macula discoidale antennarumque articulis 6-8 
nigricantibus ; haud nitidus, capite prothoraceque discrete, sat fortiter punctatis, hoc denticulis lateralibus 
conspicuis ; elytris parallelis, sat fortiter, regulariter, seriatim punctatis. 
Long. 34-33 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
We have received two examples only of this insect. ‘They have lost much of their 
pubescence, but the species is evidently distinct. On the middle of the elytra there 
is a large, common, dark mark that extends along the suture both anteriorly and 
posteriorly. The antenne are yellow, with three or four joints in the middle black. 
The eyes are large. ‘The thorax is dull, the punctures on it are not large and are 
somewhat distant; it is much narrowed behind; the denticles at the sides are 
unusually distinct. The punctuation of the elytra is extremely regular; the punctures 
are not large, but the interstices are not so large as the punctures.
