thorax, convex, subcylindrical, punctate-striate, femora thickened, 

 unarmed, tibise sulcate, the iotermediate and posterior ones emar- 

 ginate at the apex, claws appendiculate, prosternum subquadrate, 

 transverse, the anterior margin of the thoracic episternum concave. 

 The gênerai appearance of the species for which this genus is 

 proposed, is that of a Nodostoma near which the genus will find its 

 place, the diflerences consist in the long second joint of the antennse 

 which is more elongate than the third, a rare ocurrence amongst 

 the Eumolpidœ and in the thorax which is of equal widlh, not 

 narrowed anteriorly and in which the sides are evenly rounded; 

 the genus Nodostoma Motsch. contains ah'eady so many species 

 that it would not be wise to include others which difïer in the 

 above or other particulars. In the présent species the maie has a 

 thoracic dépression or sulcus at the sides of the thorax which is 

 absent in the other sex. 



PSEUDOSTONOPA BIGOLOR sp. n. 



Dark fulvous, more or less marked with black above, thorax 

 closely punctured, the sides rounded, elytra distinctly punctured at 

 the base only, the dise with a broad black band, legs marked with 

 black, the apex of the tibise and the tarsi fulvous, 



Var. Nearly black, the apex of the elytra flavous. 



Length 4 mill. 



Head closely punctured anteriorly, the clypeus longitudinally 

 striate at the anterior edge, the latter triangularly emarginate, 

 antennœ fulvous, the terminal joints more or less piceous; thorax 

 fulvous, the dise more or less piceous, closely punctured at the 

 middle, the sides with a more or less distinct transverse sulcus (çf) ; 

 elytra feebly depressed below the base, with short rows of fine 

 punctures, distinct only below the base, the latter and the apex 

 fulvous, the dise more or less black; legs fulvous, the tibiœ widened 

 at the apex as well as the first joint of the anterior tarsi in the maie; 

 below more or less piceous. . 



In the female the thorax has no sulcus and the anterior tarsi are 

 less widened, the amount of black of the elytra is variable and 

 assumes sometimes the shape of a longitudinal band, the legs hâve 

 also the knees more or less piceous in some spécimens; in one 

 variety the whole insect is nearly black, a small shoulder spot, the 

 anterior margin of the thorax and the apex of the elytra alone being 

 pale fulvous or flavous. 



EDISTUS INDICUS sp. n. 



Rounded and convex, black below, metallic blue or aeneous 

 above, the base of the antennse and the apex of the tibiae and the
