and rugosely punctured ; the thorax also similarly pointed, 

 not foveolate, but there is a slight transverse impression 

 behind the anterior angle ; the elytra, sutural stria is trace- 

 able and also a short stria near the shoulder, the others are 

 obliterated by the punctuation ; the propygidium has four 

 shallow foveas ; the pygidium, surface punctured with two 

 foveas, nearly circular, at the base ; the presternum, striaa 

 meet at both ends and are somewhat fine and parallel laterally ; 

 the meso- and metasterna are canaliculate and the latter is 

 very finely puncticulate ; the anterior tibiae have a single 

 tootli only.

Tnjpanceus junceus, sp. n. 



$ . Elongatus, cylindricus, niger, nitidus ; fronfce leviter biimpressa, 

 hand sulcato, rostro apice trigono ; pronoto antice bituberculato, 

 punctato ; propygidio pygidioqne distincte pnnctatis ; prosterno 

 parallelo marginato ; tibiis anticis 5-dentatis. 



J . Fronte concava, rostro apice obtuso reflexo ; pronoto grosse 

 punctato. 



L. 5 miD. 



$ . Elongate, cylindrical, black, and shining ; the head, 

 the rostrum is triangularly reflexed at the apex and has two 

 lateral longitudinal impression?, flat and smooth between the 

 eyes ; the thorax is punctate, not very densely, with two 

 small tubercles behind the head ; the elytra are very finely 

 and sparsely punctulate ; the pygidia are punctate like the 

 thorax, but more densely ; the presternum is laterally parallel 

 and marginate and truncate anteriorly. 



$ . Forehead concave between the eyes, with the rostrum 

 obtusely reflexed at the apex, and the punctures of the thorax 

 are larger and more close. 



This species is smaller and much less robust than nonius, 

 nasicornis, and volvulus, to which section of the genus it 

 belongs in having; the rostrum bulging at the sides. The 

 presternum is relatively shorter also than in the others 

 named. 



Hab. French Guyana. 



Tri/panmis carinirostris, Mars. 



In his description of this species Marseul says that the 

 thorax is " 4-tuberculato," but I have specimens from 

 Guiana which agree with his figure, which has only two, and 

 also with his description generally.
