of the base elevated, glabrous and impunctate, its flanking scars deep but only 

 slightly punctate; two basal lobes of the antennal club long and subequal, 

 about 5 times as loug as the joint, the last joint about "^14 times as wide as long, 

 the lobe widest beyond the middle. Prothorax about }4 wider than long, the 

 apex transverse and feebly bisinuate, the apical angles rather broadly rounded; 

 marginal groove fine and impunctate, extending inward at apex without the 

 least dilatation about ^ the distance to the middle; disk transversely convex, 

 wholly impunctate, the post-median lateral depression well marked though 

 smooth; median groove deep, terminating at some distance from the apical 

 margin. Scutellum sparsely punctate toward base, the median line im- 

 pressed except toward tip. Elytra about ^ longer than wide and nearly '2% 

 times as long as the prothorax, equal to the latter in width and with the sides 

 parallel and nearly straight, the apex circularly rounded; base broadly and 

 very feebly sinuato-truncate ; disk rather deep and vertical at the sides, gradu- 

 ally less convex and horizontal above, the striae distinct and equally pro- 

 nounced throughout, only a little more widely separated above than on the 

 flanks, the punctures distinct on the flanks but very indistinct toward the 

 suture, the intervals broadly and equally convex throughout. Meiasternum 

 well developed, the depressed side-pieces becoming broader behind, the sur- 

 . face polished, without coarse punctures near the hind angles. Middle tibiae 

 ■with three external spines, gradually more pronounced distally, the hind tibiae 

 with a single spine. Length 38.0 mm. ; width 13.0 mm. ; length of prothorax 

 9.0, of the elytra 21.0 mm. Guerrero. 



This species is closely allied to Sagittarius, but differs in its 

 larger size and relativel}^ shorter and more transverse prothorax; 

 the elj'tra are only twice as long as the prothorax in Sagittarius, 

 according to the measurements given by Dr. Kaup. 



Paxillus parTUS. — Elongate, rather narrow, depressed, the upper sur- 

 face flat, deep black and highly polished throughout, glabrous, the fine punc- 

 tures of the posterior parts of the hypomera and humeral part of the basal wall 

 of the elytra bearing very short erect hairs, the latter very dense, but not ex- 

 tending behind the humeri at the sides. Head nearly % as wide as the pro- 

 thorax, with scattered deep punctures at the sides behind the eyes and coarse 

 shallow punctures near the clypeal margin, elsewhere impunctate; posterior 

 ambient excavation rather deep, its posterior wall broadly cuspiform in the 

 paiddle and sharply defined; cephalic process consisting of a feeble transverse 

 elevation in the middle, trilobed by two feeble sulci, the lateral lobes small, 

 the median evenly convex without trace of horn, the diverging ridges from its 

 apex acutely cariniform and evenly arcuate, terminating each in a strong and 

 prominent tuberculiform process at the clypeal margin, the latter transverse, 

 straight and unmodified between the processes, the enclosed space being 

 scarcely )^ the total width of the head ; frontal margin at each side between the 

 process and the prominently angular anterior part of the ocular canthus evenly 

 sinuate; antennal club pentaphyllous, the lobes long and slender, the middle 

 the longest, and nearly 5 times the length of the joint. Prothorax nearly %
