THE CANADIAN ENTOMOLOGIST. 331 



annulate with fuscous. Pronotum robust, generally uniformly testaceous 

 or cinereo-testaceous, rarely longitudinally striped with fuscous, and then 

 the lower part of the head and lateral lobes are pallid ; median carina 

 distinct, percurrent, though the prozona, especially in the female, has a 

 prominent median tuberculous swelling ; lateral carina; sharp and pro- 

 nounced, even distinct on the prozona; disk of metazona generally 

 plane, sometimes feebly rounded, densely punctate, the process obtus- 

 angulate in both sexes ; lateral lobes terminating behind in an inferior 

 pointed process, as in T.pacifica, but placed more completely at posterior 

 margin. Tegmina, as in T. pacifica, but with the markings less pro- 

 nounced, sometimes almost wholly wanting ; hind wings feebly washed 

 with citron in basal half, beyond hyaline, but with the apical veins and 

 cross-veins fuscous (more deeply than in T. pacifica) and generally 

 with feeble remains of a transverse mesial fuscous band like that of 

 T. pacifica, but never continuous and generally altogether confined to the 

 infuscation of some but not all of the veins and cross-veins of that region, 

 and rarely shows the added infumation of some of the cells. Hind 

 femora and tibiae as in T. pacifica, the former quite as heavily marked.

This species differs from T. pacifica by its more widely angled 

 pronotal process, robuster and more angulate pronotum, the protuberance 

 of the prozonal disk, and the almost complete, sometimes complete, 

 absence of a band on the hind wings. 



Dichopetala brevicauda, sp. nov. 



Pale testaceous, the upper surface of head and pronotum tinged with 

 flavous, which terminates on the posterior part of the pronotum at a 

 rectangular bent line of reddish points, its angle at the posterior margin ; 

 lateral lobes obscurely marked with fuscous. Pronotum constricted just 

 behind the front margin, emarginate posteriorly next the lower 

 margin of the tegmina ; these are testaceous, overlapping, about 

 as long as broad, not truncate, but angulate. All the legs, but 

 especially the hind pair, very long uniform testaceous. Ovipositor 

 no longer than the pronotum, both margins serrate on distal half, besides 

 which the sides of both valves of the same portion bristle with raised rufo- 

 fuscous serrations, arranged linearly and gradually fading baseward,
