cavities bringing it into the family Lagriidae, as at present 

 denned in our text-books. The extremely elongate 

 antennae, large eyes, and general facies are suggestive of 

 the Oedemerid genus Calopus. The difference in the size 

 of the eyes in the two sexes is somewhat remarkable, as 

 is also the very small second joint to the unusually elongate, 

 filiform antennae, these characters separating the present 

 genus from Ictistygna, Pasc, all the species of which are 

 Australian. 



1. Ictistygnina filicornis, n. sp. (Plate LXIII, figs. 6, <£; 

 6a, antenna.) 



Elongate, rather narrow, somewhat flattened above, the head and 

 prothorax opaque, the rest of the surface shining, clothed with 

 intermixed decumbent pallid pubescence and long soft erect hairs; 

 obscure ferruginous, the elytra, palpi, antennae, and legs testaceous 

 or brownish-testaceous, the eyes black. Head narrowed behind 

 the eyes, densely scabroso-punctate ; eyes coarsely facetted, nearly 

 reaching the base of the head and almost contiguous above in cJ, 

 much smaller and separated by fully half their own width as seen 

 from above in 2; antennae shortly pilose, Blender, as long as the 

 body in <J, shorter in 2, joints 3-10 elongate, equal in length, 11 

 longer than 10 and constricted at about one-third from the tip. 

 Prothorax barely as wide as the head in ^, along the median line 

 (with the narrow neck) about as long as broad, densely, finely, 

 scabroso-punctate, much rounded at the sides before the middle, 

 narrowed behind, the hind angles obtuse. Elytra long, much wider 

 than the prothorax, gradually narrowed from the base in <$, sub- 

 parallel in their basal half in 9, coarsely, closely punctate. Beneath 

 sparsely, finely punctate; lifth ventral segment deeply arcuato- 

 emarginate in $.

Two males and two females, the latter now wanting a 

 portion of the antennae. I.JUicomis superficially resembles 

 a large pallid example of Ictistygna tenuis, from \\ . 

 Australia, and it is similarly sculptured above; the pro- 

 thorax, too, is of the same shape, except that the narrow 

 basal portion is less dilated laterally in the American 

 insect. The Indian Pedilid here described under the name 

 Eurygenius brunneus is also not unlike I.JUicornis, but the 

 latter has the anterior coxal cavities closed behind,
