are three specimens before me, in one of them, the thorax has a 
narrow short central ridge and the whitish hairs at the apex of the 
elytra are more numerous than in the others, 
Sybriacus parvulus Jacoby (Novit. Coleopt. 1895, p. 2). 
Fulvous, above metallic green, head and thorax closely and finely 
punclured, elylra strongly punctate-striate, femora with a small 
tooth. 
Mas. Anterior femora very strongly incrassate, their tibiæ curved 
and dilated at the apex. 
Fém, Anterior femora less strongly dilated, elytra slightly costate 
atthe sides. 
Length : 1 1/2-2 lines. 
Head rather closely and distinctly punctured, the clypeus not 
separated from the face, labrum falvous, antennæ extending to half 
the length of the body, fulvous, the terminal joints fuscous, gra- 
dually but slightly thickened, the third and following joints nearly 
equal; thorax scarcely twice as broad 3s long, swollen at the disc 
and rounded at the sides, transversely sulcate near the anterior mar- 
gin, punctured like the head, scutellum fulvous, stained with 
metallic green, elytra with a transverse depression below the base, 
strongly punctate-striate, the interstices with some minute punc- 
tures, slightly transversely wrinkled ai the sides, the shoulders pro- 
minent, underside and legs fulvous, the four anterior femora with a 
minute tooth, four posterior tibiæ slightly emarginate at the apex, 
claws appendiculate, prosternum very broad, strongly punctured. 
Antsianaka and Alaotra Sea. 
This is the first small species of the genus Sybriacus which as far 
as known up to the present time, contains three of the finest and 
largest species of Eumolpidæ much distinguished by the greatly 
enlarged anterior femora and their curved and dilated tibiæ, the 
present little species posesses all the structural characters of the 
genus as well as the metallic coloration, the female has a less 
enlarged thorax, shorter antennæ and less strongly dilated anterior 
femora. 
Sybriacosoma Jacoby (Novit. Coleopt. 1895, p. 3). 
Body ovately-rounded, glabrous, convex, antennæ filiform, thorax 
transverse, the sides entire, elytra closely and semiregularly punctu- 
red, their epipleuræ not produced below the shoulders, femora 
unarmed, the anterior ones in the male strongly incrassate, their tibiæ 
curved and dilated at the apex, posterior tibiæ not emarginate at the
