10. Scopaus marginatus, sp. n. 



Black, not very shining (greasy lustre only), the posterior 

 margin of the elytra narrowly but brightly reddish testa- 

 ceous; legs and last six joints of the antennae reddish testa- 

 ceous ; the basal half infuscate. 



Length 3 mm. 



Size and build of S. ligti/ifer, Slip., from which it differs by 

 the finer puncturation of the head and thorax, the coloration, 

 and the male characters. 



Head square, a little broader than the thorax ; the temples 

 parallel ; the posterior angles bluntly rectangular, the poste- 

 rior margin slightly emarginate. Antennae with first seven 

 joints longer than broad, gradually decreasing in length, the 

 last of them slightly oval ; eighth to tenth as long as broad ; 

 eleventh oval, pointed ; puncturation very fine and close ; 

 pubescence very fine and sparing. The thorax a little longer 

 than the greatest width, which is at the anterior angles, 

 which are obtuse but distinct ; the disc without basal 

 impressions and with a feeble trace of central line in front 

 only ; puncturation very fine and close ; pubescence fine. 

 Elytra a little longer than the thorax, longer than broad, 

 finely and closely punctured, finely pubescent. Abdomen 

 black, extreme apex brownish ; puncturation and pubescence 

 fine and close throughout. Posterior tarsi short. 



J 1 . Sixth ventral plate with deep triangular excision of 

 the posterior margin, fifth slightly emargiuate and feebly 

 i in pressed, second and third with slightly curved, transverse, 

 impressed line before the posterior borders, the concavity 

 backwards. 



Jamaica. Type in my collection. 



41. Scopceus antennalis, sp. n. 



Black, not very shining (greasy lustre only) ; elytra uni- 

 form dark brown ; legs and last joints of the antennae 

 reddish testaceous. 



Length 3 5 mm. 



This species is so similar to the preceding that a detailed 

 description is unnecessary. It differs from it by larger and 

 more robust build, the thorax more finely punctured, the 

 antennae are longer, all the joints longer than broad and the 

 first five or six infuscate, the elytra unieolorous, the abdo- 

 men more densely pubescent, and the male characters. 



cJ . Sixth ventral plate with deep triangular excisions at 

 the posterior margin ; fifth ventral plate feebly emargiuate. 



Haiti. Type in my collection.
