1907.] SPECIES OF CRYPTOCEPHALINE BEETLES. 833 



basal margin nan-owly raised ; puncturatiou rather strong and 

 distinct to apex ; surface of greenish or bluish-black coloration. 

 Prosternum fulvous, transverse. Legs black or partly fulvous. 



Hob. Merida, Venezuela. 



Very closely allied to M. obsciirellus Suff., with which I cannot 

 identify the species ; the thorax has no puneturation at all and 

 the dark spot is not placed at the middle, nor does it extend to 

 anterior or posterior margin as Sufirian describes his species ; the 

 elytra are not finely, but compai-atively strongly, punctured. 



MONACHUS DIVISUS, sp. n. 



Black ; basal joint of antennte fulvous ; thorax extremely 

 minutely punctured at sides ; elytra finely punctate-striate, a 

 broad transverse band at base, not quite extending to suture, 

 bright red. 



Length 2^ millim. 



Head black, entirely impunctate ; antennas black, the basal 

 joint fulvous, very elongate, terminal ones strongly thickened. 

 Thorax rather long, strongly subcylindrical and narrowed in 

 front, black with seneous gloss ; the sides with some minute 

 punctures ; the disc impunctate ; the base with a narrow trans- 

 verse sulcus in front of the scutellum ; the latter broad and 

 triangular. Elytra about twice the length of the thorax, rather 

 strongly punctate-striate, each stria commencing with a deep 

 puncture at the base ; the interstices very finely punctured ; the 

 entire anterior half occupied by a transverse red patch or band, 

 which at its inner lower angle is obliquely rounded and does not 

 quite extend to the suture. Under side and legs black ; femora 

 very strongly thickened. Prosternum twice as broad as long, 

 finely punctured. 



Sab. Jalahy, Prov. Goyaz, Brazil. 



]!>rot unlike M. babioides Sufi\, but the thorax with a distinct 

 aeneous gloss, the basal joint of the antennae very elongate, and 

 the elytra without apical red spot. The seneous gloss of the 

 thorax and its fine puneturation at the sides, and the much larger 

 elytral red patch which extends to the base and nearly to the 

 suture, separate the species from M. j^ustulijjennis Stal. 



StEGNOCEPHALA NIGRITARSIS, Sp. n. 



Dark fulvous ; the antennae (the basal joint excepted), apex of 

 tibiae, and the tarsi black. ; extreme basal margin of the elytra 

 black. 



Length 3|-4 millim. 



Oblong. Head impunctate ; eyes nearly touching at base ; 

 labrum and mandibles black. Antennae extending to the base of 

 the thorax, black ; basal joint fulvous, elongate, second very 

 short, third and fourth nearly equal, elongate, the following joints 

 widened, but little longer than broad. Thorax strongly narrowed 

 anteriorly, sides nearly straight, narrowly margined ; surface 

 entirely impunctate, very shining, with a short oblique depression
