ous and ferruginous, prominent, the cross-veins arranged in such a 

 manner as to form four series of diagonal ones which give to these 

 members the appearance of being crossed by that many oblique 

 ferruginous bands, the median vein seven- or eight-branched; wings 

 caudate, their apical field somewhat infuscated. Hind femora slender, 

 unicolorous; hind tibiae externally six-, internally eight-spined; pos- 

 terior metatarsus one- to two-spined, anterior and middle legs rather 

 slender, the front tibiae a little swollen and perforated internally by 

 an elliptical foramen. Subgenital plate elongate, the sides parallel, 

 longitudinally and broadly canaliculate beyond the middle, the apex 

 widely and shallowly emarginate. Cerci rather robust, curved, and 

 about the length of the hind femora.

104. Aphonomorphus hapitheformis sp. no v. 



Body somewhat hirsute and sericeous. Of medium size, but com- 

 paratively robust, and having a rather strong resemblance to a fully 

 winged female Hapithes. Bruneo-testaceous with a narrow testaceous 

 line along each side of the pronotum and the humeral angles of the 

 tegmina, and bordered below by dark brown, inclining to piceous. 

 Abdomen piceous or black. Base of the tegmina conspicuously 

 marked with a black spot. 



Head of moderate size, semiglobose, the occiput tumid, gently 

 depressed just back of, and between, the lateral ocelli. These medium 

 in size, elliptical; rostrum rather prominent between the antennae, 

 of about the same width as the greatest diameter of the basal joint 

 of the latter. Pronotum transverse, the humeral angles rounded, 

 broadly emarginate in front, behind sinuose, the middle apex sub- 

 angulate. Tegmina rather broad, a trifle longer than the abdomen, 

 regularly veined in the female, a little irregularly so in the male, 

 mediastine vein five-branched. Wings briefly caudate, slightly infus- 

 cated apically. x'\nterior and middle femora robust, the front tibiae
