CALLIEEHIPIS. 581 



8. Callirrhipis mexicana. (Tab. XXIV. figg. 17, c? ; 18, ? , antenna.) 



d 1 . Very elongate, slightly shining ; fuscous, paler beneath, the antennse ferruginous, with the basal 

 joint darker, the legs brown, with the tarsi obscure ferruginous ; rather sparsely clothed with fulvo- 

 cinereous pubescence. Head thickly punctured, transversely depressed in front and canaliculate on the 

 vertex, the eyes large and prominent ; antennae with the rami on the third and following joints very 

 , elongate. Prothorax broader than long, narrowing from the base, the sides a little constricted at the 

 middle and slightly rounded behind; the surface densely, coarsely punctate, more or less distinctly 

 canaliculate, and very deeply foveate on either side of the disc about the middle. Elytra very elongate, 

 distinctly wider than the prothorax at the base, widest beyond the middle ; each with four costse — the 

 first faint, the second becoming sharply defined beyond the middle, the third and fourth distinct, the 

 third abbreviated or coalescent with the fourth behind, the second and fourth almost coalescent before 

 the apex ; the rest of the surface rather coarsely subseriate-punctate, with the interspaces rugulose. 

 Beneath thickly, finely punctate. Legs moderately elongate ; the basal joint of the hind tarsi as long as 

 the following two joints united. 



2 . More robust, shining, glabrous and more sparsely punctured above ; blackish-brown, the head and pro- 

 thorax sometimes black, paler beneath ; the eyes smaller and less prominent ; the antennse strongly 

 pectinate from the third joint ; the elytra more dilated beyond the middle, and with the third and fourth 

 costse sharply raised behind.

Two males and three females. In this species (as in C. vestita) the second elytral 

 costa is less curved behind than in many of the allied forms, and it becomes almost 

 obliterated before the suture is reached ; the third and fourth costee, too, are more 

 prominent than usual, especially in the females, in which sex they are as much raised 

 as the second. The females vary greatly in size. The males are more sparsely 

 pubescent than the corresponding sex of C. vestita. C. mexicana ( <$ ) differs from the 

 Brazilian C. inconspicua, Waterh. ( 6 ) (1=gorp, Lap.), in having less elongate and 

 more feebly costate elytra, smaller and less prominent eyes, and shorter legs. 

 C. simplex, Waterh., from Brazil, the male only of which is known, has a longer thorax, 

 this being less dilated behind and without distinct fovea?. 



9. Callirrhipis venosa. (Tab. XXIV. figg. 19, e; 19 a, antenna.) 



3 . Very elongate, rather narrow, slightly shining ; pitchy-black, the head, femora, claws, and under surface 

 in part, obscurely rufescent, the antennae blackish-brown ; above somewhat thickly clothed with fine 

 fulvo-cinereous pubescence, beneath thickly einereo-pubescent. Head densely, rugulosely punctured, 

 transversely depressed in front, the vertex deeply canaliculate, the eyes not prominent ; antennse with the 

 rami on the third and following joints stout and comparatively short. Prothorax broader than long, a 

 little dilated behind, and rapidly narrowing forwards, slightly constricted at the middle, the sides appearing 

 sinuate ; the surface densely, rugulosely punctate, finely canaliculate, and with a deep oblique fovea on 

 either side of the disc about the middle. Elytra very elongate, subparallel ; each with four rather strong 

 costae, connected with each other and with the suture by transverse or oblique raised lines, the interspaces 

 thickly, moderately coarsely punctate. Beneath densely punctured. Legs moderately elongate, rather 

 stout ; the first joint of the hind tarsi short, shorter than the following two joints united.
