rows of cells, both above and beneath, their margins straight 

 or feebly curved; pronotum with all the carinae entire, feebly 

 elevated ; elytra elongate-oval, the reticulation rather close, the 

 discoidal area extending to or slightly beyond middle; sub- 

 costal area narrow, with but two rows of small cells. Two of 

 the five known species occur in our territory.

 long, fusiform, reaching tip of abdomen; form elongate-oblong.

 an. Side margins of paranota distinctly, though feebly, rounded; dis-

Elongate-oblong, very flat. Head, hood, 

 paranota and carina 3 of pronotum yel'owish; disk 

 of pronotum and elytra olive-gray, the discoidal 

 area of latter with a narrow oblique blackish 

 streak; sutural area with some of the cross ner- 

 vures fuscous ; ventrals pale brown. Spines of 

 head rather long, the three in front reaching 

 only to base of second antennal. Beak scarcely 

 reaching middle coxae. Joint 1 of antenna? more 

 than twice the length of 2, 3 slender, four times 

 longer than 4. Hood small with rows of minute 

 cells, triangular in front, obtusely rounded be- 

 hind, the tip of its median carina projected up- 

 ward. Elytra long and narrow, costal margins 

 broadly feebly rounded; costal area but little 



broader than discoidal one, the cells small. Length,

Elongate-oval. Ash-gray, the nervures mostly fuscous; hood and 

 paranota dull white; basal and apical joints of antenna? black, remainder 

 dark brown; legs dull yellow. Spines of head short, the three front ones 

 often matted to appear as one. Hood compressed, triangular, longer than 

 broad, its crest carinate. Elytra gradually widening, with cells increas- 

 ing in size from base to apex; costal margin very feebly curved, apical 

 one broadly rounded ; discoidal area slightly concave, narrowed at each 

 end, finely reticulate and with an oblique fuscous line crossing it just 

 behind middle. Other characters as under generic heading. Length, 

 3—3.3 mm. (Fig. 109).
