the second ; fourth and fifth elongate about equal in length, the fifth 

 sometimes feebly enlarged and angulated at the apex ; sixth to tenth 

 moderately dentate on the inner side and subtriangular ; eleventh 

 oblong and rounded at apex; the dentate joints armed with pori- 

 ferous pores and foveae on both sides of the joints. Eyes large, 

 elliptical, strongly convex, and slightly closer to each other on the 

 vertex than at the front. Pronotum wider than long, variable in 

 shape, base bisinuate, and the surface sometimes with smooth shining 

 areas. Scutellum very small and rounded. Elytra very variable, 

 base sinuate, sides smooth posteriorly, sometimes dentate, with the 

 apex emarginate, bidentate or obliquely truncate. Sternal cavity 

 formed by the mesosternum and metasternum ; mesosternum divided, 

 the lateral branches long and feebly oblique; metasternum truncate 

 in front, only feebly emarginate at middle, and with a narrow 

 longitudinal median groove on the disk. Prosternum variable; 

 anterior margin truncate, sinuate or lobed ; prosternal process rather 

 broad, feebly convex and with a groove along the lateral margins. 

 Abdomen with the first segment broadly sulcate at middle. Posterior 

 coxae strongly dilated internally, the anterior margin sinuate, and 

 the posterior margin more or less emarginate on the interior dilated 

 part. Legs feebly robust; anterior and middle femora feebly 

 swollen at middle, the posterior ones subcylindrical and feebly 

 flattened on both sides; tibiae subcylindrical, the anterior ones 

 sometimes feebly arcuate; tarsi depressed, rather broad, the first 

 joint of the anterior pair not longer than the second joint. Body 

 very variable. 



This is a very large genus and includes nearly 500 described 

 species, which are distributed throughout the warmer parts of the 

 world, with the exception of Australia and Oceania. Only a few 

 species are found in Malaysia, where they are replaced by the genus 

 Chi^sodema. Eight species have been found in the West Indies, 

 two of which are described in the present paper. Kerremans has 

 divides the genus into four subgenera, but all of the West Indian 

 species, except fulgida Olivier, belong to the subgenus Lampetis 

 Dejean, which is separated from the other subgenera by the pros- 

 terum not produced at tlie middle, but with the anterior margin 

 truncate, lobed or feebly sinuate; epistoma short, not separated on 

 the front by a transverse carina, and not declivous in front, nor con- 

 tracted on the sides. A large number of genera have been placed as 

 synonyms of this genus by Kerremans, but since their distribution 

 do not apply to the fauna covered by the present paper, the citations 

 are omitted.
