the protliorax more strongly and clensel}^ punctate ; elytra, on the other 

 liand, more finely punctate. The pair of median raised elevations on 

 the last ahdominal segment is possibly a male character only.

Originally described from Indo-China. Grebien gives further details 

 of a. species so identified by him from Formosa. Two specimens from 

 Ceylon (Kandy, ii.l8S2, G. Lewis) in the British Museum and one 

 from the Nilgiri Hills {H. L. Andrewes) in Mr. Andrewes's collection 

 agree well with individuals from Formosa that are without doubt the 

 insect so identified by Gebien. 



Keadily recognised among Indian HypopliJoei by its narrow cylin- 

 drical form, the prothorax rather longer than broad, with the anterior 

 angles seen from above slightly prominent forwards. The clypeus is 

 evenly convex in the middle, punctured like the frons, the last abdominal 

 segment strongW punctate, with a small apical tubercle. 



In form and colour H. filum resembles H. cephalotes Geb. {infra), 

 but it lacks the clypeal elevations of that species, and has an aj^ical 

 tubercle on the last abdominal segment. 



H. analis Geb., known from the Philippine Islands, Formo!?a, etc., 

 is an allied species, distinguished by having a round depression and no 

 apical tubercle on the last abdominal segment. It has not 3'et been 

 identified from India.

H. cormifiis Pic, Mel. exot.-ent. fasc. xi, 1914, p. l(j. 



H. ceplialofes was described from Formosa, while H. cornutiis was 

 from Malacca, but the species appears to have ratlier a wide distribution, 

 and in the British Museum collection is repi'esented by specimens from 

 Kumaon (if. Q. Champion), Ceylon (Dikoya, xii.1881, Balangoda, 

 iii.1882 : G. Lewis), the Andaman Islands, Tenasserim, Sumatra, and 

 Java, and from Dorey, New Guinea. 



It is of a uniform reddish colour, has the thorax considerably longer 

 than wide, the sides almost straight, slightly convergent from close 

 behind the apex to the base, and the anterior angles produced forwards. 

 The clypeus bears two parallel longitudinal elevations near the middle.
