hind angle about 90°; lateral carinae in prozona low, but well 

 distinct, in nietazona obliterate; lateral lobes only feebly convex. 

 Prosternal tubercle narrowed towards the roimded apex, but not 

 conical. Elytra in the male extending beyond the apex of the 

 abdomen, but not reachmg the hind knee, rather hyalinous, with 

 the apex rounded. Wings only a little shorter than the elytra. 

 Hind femora broader, but less incrassate. Male genitalia very 

 much the same as in A. miniaius, but the emargination of last 

 tergite is deeper and more romided; there is no prominence on the 

 last tergite ; submedian tubercles of the supra-anal plate somewhat 

 oblique, not connected with each other; lateral tubercles in the 

 shape of small oblique carinulae. 



General coloration dark-bro^vIl. Pronotum with two pale lateral 

 fasciae. Elytra reddish- browTi, with indefinite dark spots. Wings 

 bright rose, with the fore margin darkened. Hind femora with 

 three mdefmite dark fasciae on the upperside, extending into the 

 inside as well, but not reaching the lower half of the latter; the 

 imier side dirty yellow; lower inner sulcus and the hind tibiae 

 du-ty yellow ; the spines of the hind tibiae black. 



In the paratypic female the elytra do not reach the apex of the 

 abdomen. 



Dimensions of the male type are as follows : Length of body 

 (probably shrunk) 19 mm. ; of pronotum 5"5 mm. ; of elytra 13 mm. ; 

 of hind femur 12 mm. 



Dimensions of the female paratype are : Length of body 27 mm. ; 

 of pronotum 7 '5 mm. ; of elytra 16 mm. ; of hind femur 17 mm.

Rhachitopis,* gen. nov. 



Moderately rugose. Antennae very feebly compressed and 

 scarcely dilated beyond the middle. Face vertical. Frontal ridge 

 in profile straight, with the margins parallel, not at all, or but slightly 

 approximate near the fastigium, wdth the surface more or less 

 sulcate. Fastigium of the vertex strongly sloping, in profile convex, 

 forming with the frontal ridge a ^videly rounded angle, not separated 

 from the ridge by a ti-ansverse carma; its surface not strongly 

 impressed; margiris subparallel, sinuose before the apex because of 



* = rachitic-looking, because of curved hind tibiae. It is a
