632 LATHRIDIIDA. 
the length of the eye. Thorax long and narrow, without supplementary membrane, 
the side behind the middle deeply incised ; the surface coarsely rugose, very indistinctly 
bicarinate behind; a deep fovea close to each lateral excision, and a feeble groove 
along the middle. The sculpture of the elytra is remarkably deep and regular, and 
the traces of carination arising from the greater elevation of some of the interstices are 
extremely slight. One specimen. 
8. Coninomus —— ? 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
"We have received a single specimen of a very interesting Lathridiid, in which the 
thorax is shaped like that of Conithassa, but has two obsolete longitudinal elevations, 
while the elytra are very strongly multicostate. Unfortunately, this individual is not 
in sufficiently good preservation for description. 
ENICMUS. 
Enicmus, Thomson, Skand. Col. v. p. 223 (1859). 
This genus includes thirty-four representatives, and is very widely distributed. Fall 
records eighteen species from the United States, no less than twelve of which he 
treats as new. 
1. Enicmus guatemalenus, sp. n. 
Angustus, parum convexus, ferrugineus, antennis pedibusque testaceis (elytris interdum nigricantibus) ; 
prothorace transverso, subtiliter rugoso, ante basin minus profunde transversim impresso ; elytris profunde 
fortiter seriatim punctatis. 
Long. 14 millim. 
Hab. Guatemata, Capetillo, Cerro Zuni], Panajachel (Champion). 
This species belongs to the subgenus Hnicmus proper, though the prosternal carina 
is very fine ; it somewhat resembles the European £. transversus, and in Fall’s tables 
would come near E. fictus and E.mimus. The club of the antenna is long and slender, 
the ninth joint not transverse. The head is almost as long as broad, densely rugose, 
very feebly sulcate along the middle, the eyes moderately large, the postocular space 
scarcely so long as the eye, not divergent. Prothorax transverse, but small and 
narrower than the elytra, a little rounded at the sides, with a transverse depression 
in front of the base extending completely across; the surface rugose. LElytra with 
regular series of large, deep, closely placed punctures extending to the tip, none of 
the interstices carinate.
