CALLIEEHIPIS. 579 



punctured, grooved and deeply excavate in front and also deeply canaliculate on the vertex, the eyes 

 very large and prominent ; antennas with the rami on the third and following joints very elongate. 

 Prothorax transverse, strongly dilated behind, constricted at the middle, and rapidly narrowing thence to 

 the apex, widest a little before the base ; the surface densely, somewhat coarsely punctate, canaliculate, 

 depressed in the centre before the base, and deeply foveate on either side of the disc about the middle. 

 Elytra very elongate, at the base not wider than the base of the prothorax, widest beyond the middle ; 

 each with three or four faint costas, the second acutely raised from the middle and extending round to the 

 suture behind, the outer ones indistinct and sometimes almost obsolete ; the rest of the surface moderately 

 coarsely subseriate-punctate, with the interspaces rugulose ; the disc from the middle to the apex here 

 and there transversely wrinkled. Beneath closely, finely punctate. Legs moderately elongate ; the basal 

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



$ . Larger and more robust, glabrous above and nearly so beneath ; above and beneath much more sparsely 

 punctured; the antennas pectinate from the third joint, the eleventh elongate, longer than the tenth ; 

 the eyes smaller and less prominent ; the elytra dilated beyond the middle. 



Length 12|-16|, breadth 3|-5| millim. 



Hab. Guatemala, Sinanja and Senahu in Vera Paz, Capetillo (Champion). 



Three males from Vera Paz and a female from Capetillo. The chief characters of 

 C. dilaticollis are the strongly dilated basal portion of the thorax, which is widest a 

 little before the base, the grooved and deeply excavate front, the moderately elongate 

 antennal rami in the males (much shorter than in C. carinifer &c), and the sharply 

 raised second elytral costa, which extends round to the suture behind. This ridge is 

 less raised than in C. carinifer, and also less curved, the other costse being, on the 

 contrary, more distinct ; the elytral punctuation, too, is much coarser in both sexes. 

 The males of the present species vary a good deal in width.

<$ . Very elongate, broad, robust, slightly shining, brownish-black, above and beneath somewhat thickly 

 clothed with fine, decumbent, yellowish-cinereous pubescence : the antennae, the two basal joints excepted, 

 brownish-ferruginous. Head densely punctured, grooved and deeply excavate in front, the eyes very 

 lar-e and prominent : antenna? with the rami on the third and following joints excessively elongate. 

 Prothorax at the base very much broader than long, slightly dilated behind, and rapidly narrowing thence 

 to the apex, strongly constricted at the sides beneath in front, with the lower anterior angles prominent 

 and visible from above ; the surface densely, moderately finely punctate, deeply foveate on either side of 

 the disc about the middle, and also depressed in the centre before the base. Elytra very elongate, broader 

 than the prothorax ; each with four extremely faint costse, the outer one extending round to the suture 

 and connected with the others behind ; the rest of the surface subseriate-punctate, with the interspaces 

 rugulose and thickly, minutely punctulate. Beneath thickly punctured. Legs elongate, moderately 

 stout, the basal joint of the hind tarsi as long as the following two joints united ; the femora with a dense 

 fringe of short hairs beneath. 



Length 23, breadth 7| millim.

Two males, agreeing with the type in the British Museum. The insect is not 

 described by Gray or Laporte. It is the largest of the species inhabiting our region,
