Resembles in some respects angulifera Gorham known only from 

 Guatemala; but is readily separated from Gorham's species by the 

 rounded elytral punctures, which are never oblong, the color and 

 markings, and the less shining surface. In angulifera the abdomen 

 is piceous, each segment being spotted with red at the flanks; in 

 duplicata the entire abdomen is pale with no suggestion of spots. 



Two specimens, the male from Toluca, eastern Mexico, and the 

 female from Mexico D. F., Mexico, were taken by Prof. Wickham. 

 The type of this species is in his collection. 



Cymatodera wickhami sp. nov. 



Elongate, fuscous, finely, very sparsely pubescent, feebly shining; 

 antennae, palpi, metastemum, and legs pale testaceous; elytra pale, 

 with irregularly disposed, linear, fuscous markings. Antennae rather 

 slender, longer than the head and thorax; first joint stout; two to 

 eleven long, subequal in length, the outer joints subserrate. Head 

 slightly wider than the thorax, coarsely and very densely punctate, 

 feebly rugose. Thorax nearly one-half longer than wide, scarcely 

 wider at apex than at base; subapical constriction very feeble; sides 

 at middle ver>' slightly broader, moderately compressed behind the 

 middle; flanks coarsely densely punctate; disk rather coarsely trans- 

 versely rugose; apical margin very finely sparsely punctate; ante- 

 scutellar impression longitudinal, deep, surface each side of impres- 

 sion strongly elevated. Elytra nearly parallel, slightly broadening 

 posteriorly; disk rather depressed; surface with large, very shallow 

 rounded punctures, rather feebly arranged in series; the alternate 

 intervals slightly broader, extending nearly to apex, very rough and 

 distinctly punctulate; apices conjointly rounded; color pale, with 

 irregular, linear, fuscous markings, the arrangement of which tends 

 to form an irregularly limited subbasal, median, and subapical pale 

 fascia, the humeri and lateral margins being also pale. Body beneath 

 finely, sparsely punctate, the abdomen more coarsely and densely 

 punctate and moderately clothed with short, recumbent, grayisli 

 pubescence. Length 11.2 millim. 



One specimen, a male, has the fifth ventral segment broadly but 

 feebly arcuatc-emarginate ; the sixth ventral as long as broad, sides 

 arcuatcly narrowing to apex, apex broadly rounded, rather deeply 

 triangularly incised at middle; last dorsal slightly longer than last 

 ventral. 



Allied to firandis Gorham (Biol. Ccntr.-Amer., in, Pt. 2, p. 130), 

 but differing from that species, to judge by the description, in ab-
