tip than inwardly, they are equally bristly ; prothorax sloping 

 slightly on each side in the anterior part, narrower across the 

 straight base than across the apex, with the sides straight and the 

 fore and hind angles rounded, the upper sides are not much 

 depressed, the median impressed line is distinct in the posterior part 

 only of the disk, which is sparsely punctulate and pubescent ; 

 scutellum triangular, well developed ; elytra wider at the base than 

 the prothorax at its broadest part, more densely punctate and with 

 the flavescent pubescence somewhat longer than on the prothorax ; 

 abdominal segments impunctate and glabrous on the upper side 

 except the last segment, which is pubescent, in the male the second 

 one is broadly laminate and is produced as two parallel spines, each 

 equi-distant from the sides and from the middle and reaching only 

 the median part of the length of the third segment, in the female (?) 

 this lamina is equally developed, but straight and simple, and in the 

 male the penultimate segment has a median, not much raised longitu- 

 dinal keel ; under side and legs pubescent ; the two apical abdominal 

 segments are infuscate, and the basal joint of the hind tarsi much 

 longer than the second. 



Length 7 mm. ; width 2 mm.

MYRMEDONIA COMPRANSOR, n. sp. 



Male : Labram, prothorax, antennae, the three basal segments of 

 the abdomen rufescent, head black, elytra deep fuscous, with the 

 suture and a broad triangular humeral patch reddish, legs fiavo- 

 rufescent ; frontal part with a conspicuous longitudinal, very highly 

 raised keel, the head is very short behind the eyes and sparingly 

 punctulate and pubescent, the long antennas could reach the apex of 

 the prothorax, they are shaped as in M. tcnnitvbid, but the com- 

 pressed joints are not as elongated or as narrowed at the base, and 

 are thus more regularly triangular, they are also not quite so com- 

 pressed, but equally pubescent and with long bristles at apex ; pro- 

 thorax nearly as broad as long, sinuate laterally in the posterior 

 part, the angles are rounded, the base is slightly more arcuate than 

 the anterior margin, the sides of the discoidal part are very little 

 depressed, the disk very slightly convex, the median line plain in the 

 hind part, and it is minutely punctured and very briefly pubescent ; 

 elytra broader at the shoulders than the prothorax, slightly ampliated 

 laterally behind, more deeply punctured than the prothorax, and
