12. Platymetopus elegans n. sp. 



Form of P. acutiis. Cinereous; beneath and a broad dorsal stripe from 

 tlie middle of the vertex to the tip of tlie clavus pale yellow. Length 5 nmi., 

 female. 



Head narrower than the pronotum; length of the vertex about one-half 

 greater than its width between the eyes; sides of the narrow front broadly 

 waved, contracted at the antennas, a little widened below and again narrowed 

 to the apex. Clypeus long, narrowed at base, widened at the rounded apex, 

 which distinctly surpasses the cheeks. Lorse long, at their greatest breadth 

 a little wider than the apex of the front. Cheeks broad, triangular, almost 

 covering the propleuras. Pronotum a little longer than in aciitus, three-fifths 

 the length of the vertex; the angles prominent, obtuse. Elytra a little nar- 

 rowed toward the apex, not so wide as in P. aciitus, the costal area with about 

 eight strong transverse nervures. Rostrum reaching the base of the inter- 

 mediate trochanters. 



Color: \'ertex cinereous before, yellow on the posterior disc; cinereous 

 portion crossed by three longitudinal yellowish white vittae, distinguished 

 from the disc by slender brown lines; the central vitta begins at the tip of the 

 vertex, where it is distinct, and loses itself posteriorly in the yellow disc be- 

 tween the lateral vittte; these lay adjoining the central vitta and become ob- 

 solete before attaining the apex; close to each eye is an elongated whitish 

 spot, more or less obvious; margin of the head with a double slender fuscous 

 line leaving the extreme edge pale. Face yellow, pale below, with a broad 

 cinereous band on the base of the front, on the lower or apical edge of 

 which is a V-shaped white line edged with blackish. Ocelli fulvous. Eyes 

 rufous, bordered behind with pale. Antennae white, setae brown; pronotum 

 yellow, slightly discolored on the disc by the black mesonotum beneath; 

 sides with two broad cinereous bands behind each eye, edged with a blackish 

 line and separated from each other and from the blackish lateral margin by 

 narrow stripes of the yellow ground color. Exposed surf^ice of the propleura, 

 the meso- and meta-pleura outwardly, and the entire scutellum sulphur-yellow; 

 sternum and legs soiled white; tip of the tibiae and the tarsal joints em- 

 browned, the tibial spines inserted in black points; claws black. Elytra pale 

 brownish cinereous, subhyaline; broad costal margin and two or three ob- 

 scure, irregular, transverse bands on the corium whitish hyaline; cl»vus, ex- 

 cepting an obscure cinereous cloud along the outer basal margin pale yello\\-; 

 surface of the clavus and disc of the corium irregularly sprinkled with obscure 

 pale rufous dots and blotches; cinereous areas sparingly and very minutely 

 inscribed with fuscous; transverse costal and apical nervures and some spots 

 on the discal nervures dark brown, heavy; apical submargin with a brown 

 band. Venter pale testaceous, inclined to cinereous in spots, and marked 

 more or less broadly with black on the base of the connexivum; apex of the 

 pygofers and an area on the posterior margin of the ultimate ventral seg- 

 ment also black. 



Last ventral segment moderately long, with an obscure central carina; 

 posterior margin broadly rounded, with a minute central notch. 



Described from a single female examjile (No. 610). This spe- 

 cies shows no indications of the oval white or hyaline elytral spots
