314 Mr. A. Murray on Coleoptera from Old Calabar. 



nal line distinct, but not deep nor sharply defined; disk transversely 

 wrinkled, a transverse depression along the produced part of the 

 base. Scutellum testaceous, elongate-triangular, with a semilunar 

 depression. Elytra broad, truncate and emarginate at the apex, 

 deeply striate, with faint traces of punctures in the strife, most 

 easily seen in the pale spots, with two larger punctures in or 

 alongside of the third stria, one occurring in the larger pale 

 spot, the anterior margin of which is distant from the base about 

 a fourth of the length of the elytra, the other in the jiosterior 

 small pale spot, the posterior margin of which is distant from 

 the apex about an eighth of the length of the elytra ; a row of 

 larger circular punctures, with a slight elevation in the middle 

 of each, runs along or between the two striae next the mar- 

 gin ; the third and fourth, and the fifth and sixth striae show a 

 tendency to unite at the apex, and the seventh turns in at the 

 apex and runs towards the suture, terminating opposite the 

 third stria in a large circular puncture with a central elevation ; 

 the eighth and ninth stria; also turn towards the suture at the 

 apex, but are speedily effaced. The suture is testaceovis at the 

 base, and slightly so along its edge the whole way. The testa- 

 ceous spot on the shoulder does not encroach on the elytra so 

 far as the point of the scutellum ; the testaceous reflexed mar- 

 gin does not reach to the apex; the larger testaceous spot ex- 

 tends across four interstices, commencing at the second stria; 

 the smaller spot extends across three interstices, commencing 

 at the first stria. The under side is pale testaceous yellow, 

 shining, with a few scattered punctures on the segments of the 

 abdomen, from which spring hairs; the legs are of the same 

 colour; claws pectinate, 



3. L. clavicornis, mihi. PI. XII. fig. 1. 



Convexa, tumida, Isete carnea, semitranslucens; antennis com- 

 pressis, incrassatis versus apicem, nigris, ferrugineis ad basin ; 

 elytris leviter striato-punctatis ; pedibus concoloribus ; geni- 

 culis, apicibus tibiarum atque tarsi s nigris. 



Long. 5^ lin., lat. 2~ lin. 



Semitransparent ; body shining, and, when fresh, of a beau- 

 tiful bright fiesh tint, both above and below ; after being kept 



North American species, are examples of this. On the other hand, in 

 others, as in the present species, the tooth appears distinctly to form part 

 of the mentum, although it thins off and becomes semitransparent at the 

 edges, the harder texture running up its middle continuously from the rest 

 of the mentum. The truth is, that there are several forms of the mentum 

 among the species which at present are ranked in this genus, and it should 

 probably be broken up into two or three sections. In that case, the pre- 

 sent and the following species Avoidd fall under different heads.
