TACHYGONUS. 137 
12. Tachygonus flohri, sp. n. (Tab. VIII. figg. 23, 23 a.) 
Tachygonus flohri, Sharp, in litt. 
Rhomboidal, shining, black, the antenne, the anterior and intermediate legs, the posterior femora in part (the 
extreme base and a space beyond the middle are black), the base of the posterior tibie, and the last two 
joints of the posterior tarsi, ferruginous ; somewhat thickly clothed with long, erect, stiff, blackish sete 
intermixed with a few whitish hairs, the flanks of the prothorax and of the meso- and metasternum, and 
the scutellum, set with pectinate white scales; the posterior legs, and the anterior and intermediate 
knees, strongly nigro-setose, the sete of the hind femora becoming whitish towards the base. Rostrum 
almost smooth, punctured along the sides. Prothorax thickly punctate, except along the smooth narrow 
median space. LElytra broad, transversely cordate; seriato-foveolate, the interstices narrow, asperate, 
and somewhat raised. Posterior femora moderately elongate, armed with two subcontiguous teeth—the 
inner one long, the outer one shorter and sometimes inconspicuous. Posterior tibiz sinuate, the claw 
at the outer apical] angle large. 
Length 14, breadth 12 millim. 
Hab. Mexico, Juquila in Oaxaca (fohr). 
Four specimens. A small strongly setose form, with seriato-foveolate elytra, 
bidentate, nigro-annulate posterior femora, and greatly developed claw at the outer 
apical angle of the posterior tibie. 
13. Tachygonus bidentatus, sp.n. (Tab. VIII. fig. 24, hind leg.) 
Rhomboidal, shining, black, the antenne, tip of the rostrum, anterior and intermediate legs, basal half of hind 
femora, and apical joint of hind tarsi, ferruginous; somewhat thickly clothed with long, fine, erect, 
fuscous sete, the flanks of the prothorax and of the meso- and metasternum with pectinate white scales ; 
the posterior femora and tibie and anterior and intermediate knees fusco-setose. Prothorax rather 
coarsely punctate, except along the narrow smooth median space. LElytra broad, transversely cordate ; 
seriato-foveolate, the interstices narrow and somewhat raised. Posterior femora moderately elongate, 
armed with two slender, distantly-placed teeth. Posterior tibiz# feebly sinuate, the claw at the outer 
apical angle small. 
Length 14, breadth 13 millim. 
Hab. Guatema.a, San Juan in Vera Paz (Champion). 
One specimen. Near the Mexican 7. flohri, but with the setee much finer and 
shorter, the hind femora and tibie not so stout and blacker (the basal half of the 
femur alone rufous), the femora with two slender distantly-placed teeth, the tibial claw 
small. There is no scutellar spot in either of these insects. 
14. Tachygonus flavisetis, sp.n. (Tab. VIII. figg. 25, 25 a.) 
Rhomboidal, shining, black, the elytra piceous or ferruginous, the rostrum, antenne, and legs (a small patch 
on the posterior femora, including the larger spine, and the outer half of the posterior tibiw, excepted), 
rufo-testaceous; somewhat thickly clothed with long, fine, erect, ochreous sete, the flanks of the 
prothorax and of the meso- and metasternum set with pectinate white scales; the posterior femora and 
tibice with ochreous and blackish sete. Prothorax sparsely punctate, except along the smooth, narrow, 
median space. LElytra transversely cordate; seriato-foveolate, the interstices very narrow, smooth, and 
somewhat convex. Posterior femora moderately elongate, subclavate, armed with one long black spine, 
and sometimes with a pallid spine adjacent to it. Posterior tibie sinuate. 
Length 14, breadth 17-1} millim.
