c? . Thorax obscure ochraeeous, with seven areolets, the ridge 

 dividing the two lateral ones not rery distinct. Elytra very little 

 enlarged towards the apex, obscure oehraceous at the base ; each 

 elytron with four well-marked costse, the interstices with two rows 

 of rather strong and distinct punctures, the rows divided by a fine 

 (but scarcely elevated) line. 



2 . Larger than the male (4|-5 lin.\ the thorax and elytra of a 

 clearer yellow. It somewhat resembles Metriorrhynchus astutus; but 

 the discoidal areolet of the thorax is narrow, elongate lanceolate, 

 and the elytra have scarcely any pubescence.

Second joint of the antennae small, but distinct, the third joint 

 of the same form, but one third larger ; the fourth as long as the 

 two preceding taken together, and (at its apex) a little thicker ; the 

 following joints of the same form as the fourth, but becoming more 

 slender. Thorax somewhat transverse, rather strongly constricted 

 before the posterior angles, which strongly diverge and are acute ; 

 the mesial areolet is verj- broad, it nearly extends to the anterior 

 and posterior margins, and is connected at the sides by an oblique 

 carina on each side. The elytra have a reddish-yellow spot on the 

 humeral angle ; each elytron has seven costae, the second, fourth, and 

 sixth much stronger than the others ; the intervals have well defined 

 transverse nervures which divide the surface into squares or only 

 slightly transverse spaces. 



EROTIDES. 



Rostrum none ; forehead produced into a process between the 

 antennae. Antennae simple : the second joint small, but distinct. 

 Thorax trapezoidal, with seven areolets as in Platycis minutus. 

 Elytra parallel ; each elytron with four strong costae ; the interstices 

 with transverse costae, which are placed somewhat close together, 

 frequently oblique, or divided so as to form the letter Y placed 

 horizontally <. 



The type of this genus is Eros oblitus, Newman. It approaches 

 most nearly to Platycis, but the sculpture of the elytra is quite
