318 THE CANADIAN ENTOMOLOGIST 



slightly darker between carinae of pro- and mesonotum. Tegmina 

 hyaline, veins white speckled with brown dots, six irregular light 

 brown spots in basal half, one at end of clavus, one at base of media, 

 one at middle of costa, one at middle of radia and two in median cells ; 

 a broad brown mark from end of clavus across tegmina to near 

 costal margin, and along hind margin to near end of cubitus, along 

 second median cell to apex and from end of costal cell to end of 

 radia; wings hyaline with white veins. 



Pygophor round, a small pointed process on medio- ventral 

 edge, lateral edges subangularly produced; anal segment a little 

 longer than broad, tubular with anus situate within apex; styles 

 reaching end of anal segment, narrow, flattened, straight on ventral 

 (inner) edge, slightly sinuous on dorsal (outer) edge, narrowing to 

 near apex, where it broadens out and bends at right angle to main 

 part, apex truncate. 



9 Anal segment shorter than in male, anal style narrowly 

 lanceolate. 



Length 2.5 mm.; tegmen 4.3 mm.* 



Hab. — Mount Maquilin, living at base of leaf-sheath of bam- 

 boos among a white, flocculent secretion. Prof. C. F. Baker 

 called my attention to this and the following species when at 

 Los Banos. (Baker and Muir, February.) 

 Bambucibatus, gen. nov. 



Head narrower than thorax base as wide as length, apex 

 much narrower than base, truncate or but slightly curved, lateral 

 carinae large, an exceedingly obscure medio-longitudinal carina; 

 length of face more than double the width, base slightly narrower 

 than apex, the simple median and lateral carinae well developed, 

 clypeus tricarinate; antennae a little longer than face, joints sub- 

 equal in length, first broad, flattened narrow at base, wide at apex, 

 subtriangular, a keel down middle, second terete, thick. 



Pronotum roundly and shallowly emarginate posteriorly, 

 tricarinate, lateral carinae straight or slightly convergingly curved, 

 distinctly reaching hind margin; mesonotum tricarinate. Hind 

 tibiae with one basal, one median and five small apical spines; 



•Measurements are from apex of vertex to anus and from base to apex of one 

 tegmen.
