and has the head more orblculate, and is remarkable by 

 the sparing punctuation of the hind body. 



Tesba Belti, n. sp. Nigra, nitida, capite supra sub- 

 opaco, dense rugoso-punctato, subtus cum lateribus parcis- 

 sime punctato ; antennis articuhs 4 — 10 valde transversis. 

 Long. corp. 21 mm. 



Upper surface of head covered with dense, extremely 

 coarse and deep punctures ; the pimctures at the hind 

 angles, however, are only sparing, and at the sides behind 

 the eyes are almost absent ; its under surface is black and 

 shining, and bears only a very few rather coarse punctures. 

 The extreme apex of the hind body is distinctly reddish. 



Found by Mr. Belt at Chontales, and named after him. 



Obs. — This species almost exactly resembles T. lati- 

 cornis (Tr. Ent. Soc. 1876, p. 195), except in the sculpture 

 of the head. 



Pcederus Salvini, n. sp. Apterus; elongatus, niger, 

 antennis palpisque testaceis, elytris viridi-cteruleis thorace 

 multo minoribus. Long. corp. extens. 13 — 15 mm. 



Head broad and large, coarsely and moderately closely 

 punctured, black and shining ; antennas about as long as 

 head and thorax, rather slender, yellow, 3rd joint very 

 long, quite twice as long as 2nd ; of 6 — 1 1 each is a little 

 shorter than its predecessor, the lltli being markedly 

 shorter than the preceding one. Thorax large and convex, 

 the front and front angles greatly rounded, the sides much 

 narrower towards the base ; it is shining black, distinctly 

 but neither coarsely nor closely punctured, with a broad 

 space along the middle impunctate. Scutellum dull black, 

 the exposed portion impunctate. Elytra a good deal 

 shorter and narroAver than the thorax, the shoulders very 

 narrow ; they are of a greenish or bluish colour, and bear 

 coarse punctures, the interstices of which are very iiTCgular 

 and uneven. The hind body is black, and is rather 

 sparingly but distinctly punctured. The legs are black, 

 with the tarsi pitchy or pitchy-yellow ; the front tarsi rather 

 broad, and parallel-sided, distinctly more dilated in the 

 male. 



The excision on the apical abdominal segment in the 

 male is rather large and deep, and the segment preceding 

 it is more closely punctured on the middle than elsewhere. 



Found at Aceytum, at an elevation of 5,100 feet, by
