 India, Malabar, Belgaum, Kanara. 



Madura a March and April, fljing to light at night. > This 

 very peculiar insect has the eyes enorraously developed, and 

 deeply sulcate above; the groove or sulcation partly divides theeye. 

 The eyes are so developed beneath that they become contiguous, 

 and are finely facetted. The antennae are 12-jointed, without 

 rami. 



I hâve no doubt whatever that the proper place for this genus and 

 for Dioptoma, is in proximity to Dodecatoma, and I think they 

 are ail, with my genus Haplocladon and Diplocladon hest placed in 

 the Drilidae. While the great developement of the eyes hère and in 

 PJiengodes points to some association with the LampyridaB, I think 

 thatit will prove, that they feed either upon those insects in sorae 

 of their stages, or are attracted by their light to Molluscan diet. 

 I do not think the habits and mode of feeding of our common 

 Drilus is yet fully known. 



59. Dioptoma Adamsi Pascoe, Journ. of Ent., I, 118, t. 5, f. 2. 

 India, Kanara, Dacca. 



The occurrence of this insect at Kanara is of the greatest inte- 

 rest it having been originally recorded from Dacca at the raouth of 

 the Brahmaputra River, and therefore almost as far as possible in 

 the Indian peninsula, from the présent record. Nor do I think it has 

 been received since, in any numbers at least, while M'' T. R. D. 

 Bell found some fifteen spécimens. 



It is even more singular in the apparent fission of the eye than 

 Ochotyra, although the upper and under lobes are not really sepa- 

 rated, obsolète and fine facets being to be seen in the sulcus. The 

 under lobes are large, contiguous beneath, and much more coarsely 

 facetted than the upper, while the upper lobe is again divided into 

 two portions by an oblique transverse dépression. The head and 

 thorax are coarsely and confluently punctate. The elytra are 

 brown, with three or four raised nervures, anastomosing near the 

 apex.
