the same species in the Vienna Museum collection from Amboina (marked 

 DolescJiali, M. G.) have merely a trace of the middle frontal carina, and 

 the prothorax is comparatively smaller. 



Gonates Oermarii was received by Mr. W. S. Atkinson from Java. 



Kaup describes Laches Gomptonii from Ceylon. I have not seen it.

This is a very common species in Sikkim, Assam, the Naga and Cachar 

 hills. Indian specimens exactly agree in structure with the large Javanese 

 type form, but their usual size is only 40 m.m., and I never saw one 

 exceeding 45 m.m. In Javanese specimens generally only the ninth and 

 tenth rib of each wing are punctated and hairy near the shoulder, while 

 Indian specimens have, as a rule, the whole of the seventh and ninth rib 

 punctated ; it is very rarely that the pits entirely disappear on the seventh. 



16. AcEEAirs EMAEGINATTTS, Fabr. 



An extremely variable species, both in general size, as well as in the 

 shape of the two marginal processes of the clypeus ; the left one being some- 

 times sharply pointed at the end, or scarcely bipartite, as in Percheron's 

 pilifer. The seventh and ninth ribs of the elytra are as a rule entirely 

 punctated, very rarely is the seventh smooth. The smaller forms, between 

 30 and 38 m.m., are, I think, mostly males, they have the furrows of the 

 wings perceptibly punctated ; the larger specimens, about and above 40 m.m., 

 appear to be mostly females, the furrows of their elytra are almost devoid 

 of punctations. 



The species occurs in Sikkim, Assam, Cachar, but is much rarer than 

 A. grandis. I also obtained it on Penang hill, and from Johore ; in the 

 Vienna collections are specimens from China, Luzon, and Manilla. 



Kedtenbacher's JPassalus Nicoharicus from Sambelong (Grreat Nicobar) 

 is also undoubtedly this species, and neither a Macrolinus nor a Basilianus. 



The next genus, Basilianus, is the most numerous in species. I possess 

 specimens of the four species described by Kaup, and three others which I must 

 regard as new. This is as yet almost the only instance in which I have been 

 obliged to transgress Kaup's limit of five species. I took considerable pains 

 to ascertain whether these species could possibly belong to any of the other 

 genera of Eriocnemince, but they do not answer to the characteristic of any 



process between the anterior coxge grooved. Waist, below, smooth, with an elongated 

 scar on either side. Metasternum smooth ; on the sloping corners rugosely punctated. 

 Sides of abdominal segments and the posterior part of the last segment mostly finely 

 punctiited. No hairs are seen on the elytrae ; the middle tibiae are moderately hairy, 

 the hind ones somewhat less so. 



Habitat— Australia J a single specimen in Dr. C. Felder's collection.
