and the hind angles more distinctly carinate. The localities are all on the Atlantic 

 slope. A specimen from Sabo is figured.

In this species the elytra are unusually elongate (more than three times the length of 

 the thorax), and considerably wider than the thorax, a little rounded at the sides, and 

 somewhat rapidly narrowed from about the basal third. The thorax is convex, subcylin- 

 drical, rounded at the sides in front, with very long, acute, divergent, feebly carinate 

 hind angles ; the surface is closely, coarsely punctate, and somewhat deeply canaliculate 

 behind ; the marginal carina is incomplete, and the basal incisures shallow. The elytra 

 are finely punctate-striate. A specimen from Calderas is figured. 



24. Agriotes curticollis. (Tab. XXIII. fig. 14, $ .) 



Elongate, narrow, somewhat fusiform, convex, shining ; piceous or brown, the hind angles of the prothorax 

 and the suture and the outer part of the elytra obscure testaceous in one specimen ; the antennae and 

 legs brownish-testaceous ; above and beneath rather sparsely clothed with yellowish-cinereous pubescence. 

 Head densely, finely punctate ; antennae reaching the hind angles of the prothorax in the female, slightly 

 longer in the male, joint 3 a little longer than 2, and almost as long as, but narrower than, 4. Prothorax 

 much broader than long, the sides rounded anteriorly, subparallel behind in the male ; the hind angles 

 long, narrow, acute, and divergent, finely carinate ; the surface sparsely, very finely punctate, obsoletely 

 canaliculate behind ; the base feebly incised on either side ; the marginal carina completely obliterated at 

 the middle. Elytra three and two-thirds the length of the prothorax, and broader than it, somewhat 

 rounded at the sides, narrowing from a little below the base in the male, from about the basal third in 

 the female, the apices narrow and conjointly rounded; finely punctate-striate, the interstices almost flat 

 and very finely, rugulosely punctate. Beneath closely and finely, the presternum and propleurae sparsely, 

 punctate. Hind coxal plates very little widened inwards.

Hal. Costa Eica, Volcan de Irazu 6000 feet (Bogers) ; Panama, Volcan de Chiriqui 

 4000 feet (Champion). 



A male from Chiriqui and a female from Costa Eica. In its very elongate elytra this 

 species resembles A. longipennis, but differs from that insect in the relatively longer 

 third joint of the antennae, and the shorter, more sparsely and more finely punctured 

 thorax, which has narrower and more acute hind angles. From A. vaccinus it may be 

 known by the short thorax, with feeble basal incisures, &c. The Costa Eican specimen 

 is figured.

25. Agriotes quadraticollis. (Tab. XXIIL fig. 15.) 



Moderately elongate, convex, subopaque, the elytra slightly shining ; piceous or brown, the prothorax with the 

 sides behind, or the hind angles, and the sides of the abdomen, ferruginous, the elytra sometimes with the 

 sides or a submarginal vitta obscure testaceous, the basal joint of the antennae and the legs testaceous ; 

 above and beneath thickly clothed with pale yellowish-cinereous or pale greyish pubescence, the elytra in
