PAUSSIDiE. 



larger, and the fourth longer, somewhat fusiform and narrowed 

 at the apex ; labial palpi 3-jointed, with the last joint about 

 twice as long as the second, narrowed towards the apex, which is 

 subtruncate ; ligula large, ovate, setose at the apex ; pronotum 

 formed much after the style of Euplatifrliopalus aplustrifer, 

 Westw., the front part having the sides much expanded and pro- 

 duced behind, and the posterior part forming a broad collum or 

 neck ; elytra long, parallel-sided, entirely covering the abdomen, 

 with the shoulders much produced and almost meeting the 

 tufts of hairs on the posterior angles of the front part of the 

 pronotum ; legs rather short, very slightly compressed, tibiae 

 without spurs. 



Range. Two species only are known of this peculiar genus, one 

 taken by Fea in Burma, and the other (two specimens) in China 

 by J. J. "Walker. It is especially interesting as being a primitive 

 form, and as connecting Paussus more closely with the CarabidjE. 

 The species were not found in company with ants, but as they 

 have, as pointed out by Desneux (Grenera Iusectorum, Paussid^:. 

 p. 7), the coenogenetic character of secreting tufts of hairs on the 

 pronotum, they are probably associated with them.

Elongate-oblong, shining, head and pronotum of a light pitchy 

 testaceous colour; head short and 

 broad, raised in the middle, with the 

 eyes large and prominent, occupying 

 the whole of the sides ; antennae long 

 and slender, as long as head, pronotum, 

 and a fourth part of the elytra ; pro- 

 notum transverse, the anterior part 

 broad and crescent-shaped, expanded 

 at the sides, with two large impressions 

 on the disc, divided by a longitudinal 

 raised line, posterior angles bluntly 

 and strongly produced and terminating 

 in a fascicle of hairs, the posterior part 

 forming a distinct collum or neck, 

 which is not quite as wide as the head 

 with the eyes ; elytra long, parallel- 

 sided, punctured, with the humeral 

 augles strongly and roundly produced

(After Desneux.) posterior portion of the pronotum j, 



black, with the base more broadly, and 

 the suture, apex and margins very narrowly, yellowish ferruginous; 

 expansions at apex narrow, but distinct; pygidium completely 

 covered ; legs moderate, rather slender, pitchy, with the tarsi
