CALLIEEHIPIS. 577 



obscure ferruginous ; rather sparsely clothed with fulvo-cinereous pubescence. Head coarsely, unequally 

 punctate, transversely excavate in front and deeply canaliculate on the vertex, the eyes very large and 

 prominent ; antennae with the rami on the third and following joints excessively elongate. Prothorax 

 broader than long, rapidly and obliquely narrowing from the basal third forwards, appearing dilated 

 behind, compressed anteriorly at the sides below ; closely, coarsely punctate, depressed in the centre before 

 the base and deeply foveate on either side of the disc about the middle, and with indications of a smooth 

 median line. Elytra elongate, at the base slightly wider than the basal portion of the prothorax, widest 

 beyond the middle ; each with three distinct costse — the second longer than the others and extending 

 round to the suture posteriorly, and with traces of a fourth behind midway between the third and the margin ; 

 the rest of the surface closely, coarsely, subseriately punctate, the interspaces transversely rugulose and 

 with a few widely scattered excessively minute punctures. Beneath densely, finely punctate. Legs 

 moderately elongate ; the basal joint of the hind tarsi as long as the following two joints united. 



$ . Eyes smaller and less prominent; antenna? with the joints from the third (5-11 broken off) each with a 

 short, stout ramus ; head and prothorax very finely and sparsely pubescent, the latter canaliculate in 

 front ; the elytra, except along the outer margin, almost glabrous (short minute hairs are visible under a 

 strong lens), and dilated beyond the middle ; the under surface more sparsely punctured. 



Length 18-19, breadth 6|-6| millim. 



Hal. Nicakagua, Chontales (Belt). 



One pair. Allied to C. childreni, but smaller, less elongate, more shining, and more 

 sparsely pubescent in the male sex ; the elytra with much more distinct costse, the 

 second curving round to the suture posteriorly, and the interspaces between the 

 irregular rows of punctures very much smoother, the thorax more parallel behind. 



3. Callirrhipis obsoleta. (Tab. XXIV. fig. 10, genitalia, c? .) 



cJ . Yery elongate, slightly shining ; fuscous, paler beneath, the head and prothorax sometimes black, the 

 antennae ferruginous, with the basal joint infuscate, the legs brown, with the tarsi obscure ferruginous ; 

 somewhat thickly clothed with fine yellowish-cinereous pubescence. Head closely 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, rapidly narrowing from a 

 little before the base to the apex, the sides slightly rounded behind ; the surface closely, coarsely punctate, 

 more or less distinctly canaliculate, and usually obsoletely foveate on either side of the disc about the middle. 

 Elytra very elongate, widest beyond the middle ; each with four raised lines or costse, the second consider- 

 ably raised from the middle onwards and extending uninterruptedly round to the suture near the apex, 

 the others not very distinct, the third and fourth abbreviated and sometimes obsolete ; the rest of the 

 surface rather coarsely subseriate-punctate. Beneath thickly, finely punctate. Legs moderately elongate, 

 the basal joint of the hind tarsi as long as the following two joints united. 



Length 12|-16, breadth 4-5 millim. 



Hob. Mexico, Toxpam, Cordova (Salle), Jalapa (Edge). 



Five males. Allied to C. carimfer, but much smaller and less robust, with the frontal 

 excavation transverse and rather shallow, the second elytral costa much less raised and 

 the others more distinct, the thoracic foveas shallow or obsolete, the antennal rami 

 shorter, &c. From C. mexicana ( 6 ) it may be separated by the form of the second 

 elytral costa, which in the present species curves round to the suture behind, and the 

 shallow thoracic fovese. From C. dilaticollis it differs in the less deeply excavate front, 

 the less dilated thorax, and the shallow thoracic fovese. 



In one of the Toxpam examples the eyes are smaller and the antennal rami less
