than 10. Pro thorax convex, transversely cordate, deeply grooved 

 at the base, narrowly and sharply tubulate in front. Elytra long, 

 narrowed from the base in jj, subparallel in $, depressed on the disc 

 anteriorly, the punctures confusedly arranged and separate one 

 from another. Beneath, minutely punctate ; fifth ventral segment 

 emarginate, and the penis-sheath narrow and acuminate, in <J. Legs 

 long, slender, the tibiae setulose externally.

A long series, including two specimens received by the 

 Museum in 1844. The description is mainly taken from 

 the numerous examples captured by Commander Walker 

 in 1901. It is separable from all the allied forms by the 

 very fine, dense puncturing of the head and prothorax, 

 its elongate, narrow shape, and the comparatively slender 

 limbs. The apical joint of the antennae is not elongated 

 in either sex, the antennae themselves being very slender 

 and subfiliform. It is somewhat remarkable that the 

 species has remained so long undescribed. 



ICTISTYGNINA, 11. geil. 



Head with an abrupt narrow neck; eyes in $ extremely large, 

 occupying the whole of the sides of the head, in $ much smaller, 

 feebly sinuate in front ; mandibles unemarginate at tip ; maxillary 

 palpi long, narrow, joint 4 elongate, cultriform, as long as 2; 

 antennae filiform, very long in both sexes, joint 2 extremely short; 

 prothorax transversely cordate, immarginate laterally, narrowly, 

 abruptly tubulate hi front, deeply grooved within the basal margin ; 

 elytra long, subparallel, confusedly punctate, the epipleura very 

 narrow, incomplete; anterior coxae large, conical, contiguous, the 

 cavities narrowly closed behind by the inward extension of the pro- 

 thoracic epimera; intermediate coxae separated anteriorly by an 

 extremely narrow laminiform process, the posterior pair also 

 narrowly separated; ventral segments 2-5 subequal in length; 

 legs long, rather slender; tibiae asperate, the spurs short; tarsi 

 with the penultimate joint broadly lobed, the claws rather small, 

 widened at base ; body elongate, villose. 



Type, I.filicornis. 



The type of this genus, from Brazil, may be described 

 as a Pediliform Lagriid, the narrowly closed anterior coxal
