10. Callirrhipis tenuipes. (Tab. XXIV. fig. 26, <s .) 



cJ . Very elongate, narrow, depressed, slightly shining ; pitchy-black, the basal margin of the prothorax, the 

 scutellum, antennae, legs, and under surface fusco-ferruginous ; somewhat thickly clothed with fine, 

 appressed, silky, yellowish-cinereous pubescence. Head thickly, finely punctate, grooved and excavate in 

 front and canaliculate on the vertex, the eyes large and very prominent ; antennae with the rami on the 

 third and following joints very elongate. Prothorax transverse, strongly dilated behind, the anterior 

 portion narrow ; the surface thickly, finely punctate, canaliculate in front, depressed in the centre behind, 

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

 beyond the middle, much wider than the prothorax ; each with a single sharp costa on the middle of the 

 disc, obsolete in front and curving round to the suture near the apex, and also with indications of two 

 faint raised lines ; the rest of the surface rugulose and with scattered fine punctures, between which other 

 excessively minute punctures are visible ; the disc here and there transversely wrinkled. Beneath 

 densely, finely punctate. Legs long and slender ; the basal joint of the hind tarsi elongate, nearly as long 

 as the following three joints united ; the hind tibiae sinuous. 

 Length 12|, breadth 3| millim. 



Hal. Mexico {Salle). 



A single specimen in the Salle collection, without more definite locality. C. tenuipes 

 may be known from all our other species by the long and slender legs, the basal joint 

 of the tarsi being unusually elongate ; the thorax, too, is very narrow in front and 

 strongly dilated behind.

Originally described from a single male example from Coban, a locality supposed by 

 Hope to be in Colombia, instead of in Guatemala. 



We have received eighteen males and eight females (varying from 9-15 millim. in 

 length), one of the former (from Zapote) merely differing from Hope's figure in having 

 the thorax almost immaculate, and the base of the antennae and the femora darker. 

 The insect is extremely variable in colour in both sexes, and the basal joint of the 

 antennae and the femora to near the tip are sometimes ochraceous or rufo-testaceous. 

 The following are the chief colour-varieties : — 



a. Head, prothorax, and elytra testaceous-red or ochraceous, a spot on the middle of the vertex and a median 

 vitta on the prothorax sometimes black. ( d $ •) (Fig. 25, $ .)— Guatemala, Nicaragua, Panama.
