KHYNCHOPHOEA. 



consisting mainly of two broad, irregular, oblique fasciae, which are connected with a narrow sutural 

 stripe. Head closely punctate; rostrum ( g ) strongly arcuate, stout, compressed, much shorter than the 

 prothorax, abruptly widened, canaliculate, and closely punctured at the base, the long apical portion 

 sparsely, finely punctate above, sulcate and crenate on each side beneath, ( $ ) with the apical portion much 

 more slender, almost smooth, above and beneath, the frontal fovea rather deep. Prothorax a little 

 longer than broad, narrowing from about the middle (in one tf from Ecuador rounded at the sides and as 

 broad as the elytra), tubulate in front, feebly bisinuate at the base, somewhat closely punctate, flattened 

 or depressed on the disc posteriorly. Scutellum elongate-triangular, flattened. Elytra oblong-subcordate, 

 usually wider than the prothorax, finely punctate-striate, the interstices minutely punctate down the 

 middle. Pygidium thickly punctate, somewhat convex in the $ , densely fulvo-pilose at the tip in both 

 sexes. Beneath sparsely punctate. Anterior and intermediate coxag with a cluster of fulvous hairs. 



Var. a. Coloured as in the type, but with the oblique black fascia below the base of the elytra divided into 

 two spots and the second fascia transverse. 



Var. /3. Black, the prothorax with a v-shaped mark at the base and an oblique evanescent stripe on each 

 side, and the elytra with a small spot on the shoulder, another on the disc below the base, and a curved, 

 angulate, or oblique patch at about the middle, rufous. 



Yar. y. Black, each elytron with a transverse or oblique spot below the base and an oblique mark at about 

 the middle (sometimes almost obsolete) rufous, the prothorax sometimes faintly rufo-maculate. 



cf. Ventral excavation very broad, coarsely, closely punctate, and extending forwards along the whole 

 length of the metasternum, the fifth segment pilose ; anterior and intermediate femora densely, and the 

 posterior pair very sparsely, fulvo-pilose beneath; anterior tibiae with a dense fringe of long fulvous hairs/ 



$ . First ventral segment unimpressed ; femora almost bare, the anterior tibiae fringed with very short hairs. 



Length 9f -14, breadth 3-5 millim. ( tf $ .)

Numerous examples, the extreme forms occurring in the same localities in 



both 







Costa Rica and Panama. The sexual characters are extremely well marked, the male 







being easily recognizable by the stout, inferiorly sulcate, crenate rostrum, the densely

ciliate anterior tibiae, &c. The tuft of hair at the apex of the pygidium is present in 

 both sexes. M. dasyurus is more elongate than M. rimoratus (Gyll.) (the $ only of 



which has been described), and has a more closely punctured prothorax. M. ohsoletus 















• 





(Gyll.) (the type of which, a 6 , I have also seen) has the intermediate and posterior 

 tibiae of the male subangularly dilated at about the middle, the prothorax smoother, &c.

Sphenophorus submaculatus, Chevr. in Mus. Brit. 



Elongate, subfusiform, narrow, flattened above, somewhat shining ; black, the prothorax ferruginous, with 

 a lanciform median vitta on the anterior half and an elongate streak on either side of it at the base 

 black, the elytra ferruginous, with a triangular or oblique patch near the suture before the middle and 

 an interrupted submarginal stripe black, the rostrum and legs also in part ferruginous. Head sparsely 

 punctate, transversely grooved between the eyes ; rostrum strongly arcuate, a little shorter than the 

 prothorax, moderately stout, compressed, abruptly widened near the base, closely punctate throughout, 

 in the <J angulate near the tip, shallowly sulcate, and irregularly serrate beneath, in the $ sub- 

 cylindrical, a little more slender, and not serrate beneath. Prothorax much longer than broad, more or 

 less rounded at the sides, abruptly tubulate in front, subtruncate at the base ; densely, rather coarsely, 

 punctate, the disc with a shallow oblong depression behind. Scutellum narrow, elongate- triangular,
