slightly wider midway, convex, uniseriately granulate, with a median 

 row of erect, stout, j^ellowish-cinereous setae, with numerous much 

 smaller, scalelike setae on sides of each interspace and between the 

 larger setae ; declivity without special modifications. 



Male. — Similar to female in habitus but with frons strongly con- 

 cave, bordered at each side by a sharp, elevated ridge. 



Type loccdity. — Panama Canal Zone. 



Host. — Unknown.

Genus PHRIXOSOMA Blandford 



PHRIXOSOMA MAGNA, new species 



Plate 17, Figures 37-40 



Piceous-brown, with elytra lighter brown ; 3.91 mm. long, 1.93 times 

 as long as wide; larger and much stouter than Phrixosoma rude 

 Blandford. 



Frons (fig. 38) convex, opaque, densely, finely granulate through- 

 out, with fine median carina on lower half, somewhat flattened at each 

 side; vestiture of fine, rather short, dense, yellowish hairs which are 

 inconspicuous except in profile. Eye divided, the parts entirely 

 separated (fig. 39) by a broad area having the texture and vestiture 

 of the frons; facets of moderate size. Antenna (fig. 40) with scape 

 long, slender, 2.46 times as long as 6-segmented funicle, club longer 

 than funicle, 1.28 times as long as wide, pubescent, with 3 nearly 

 straight sutures, marked by rows of longer setae, only the first suture 

 partly septate. 



Pronotum 1.35 times as wide as long, widest behind middle; pos- 

 terior outline bisinuate, feebly margined toward sides, posterior lateral 

 angles broadly rounded, sides not margined, very strongly arcuate, 

 very broadly rounded in front, surface opaque, finely, densely granu- 

 late, with fine, short hairs ; median line narrowly elevated on less than 

 posterior half. 



Elytra wider than pronotum and 2.06 times as long, 1.33 times as 

 long as wide; bases margined and slightly elevated, finely granulate- 

 crenate; sides weakly arcuate on anterior two-thirds, more strongly 

 behind, apex rather narrowly rounded; surface opaque, cinnamon 

 brown, inf umated with piceous brown on humerus ; striae deeply im- 

 pressed, narrow, punctures small and moderately spaced ; interspaces 

 broad, weakly convex, densely, finely granulate, with fine, short, silky, 

 cinereous hairs, similar on disk, sides, and declivity.
