 Pronolum slightly expanded above the anterior coxiE and with the lateral margins denticulate through- 

 out. Anterior coxae slightly curved, attenuate beyond the middle and slightly expanded again before the 

 extremity, front lateral carina with about six moderately large teeth: anterior femora half as long again 

 as tlie coxae, attenuate, the lower carina denticulate to the base: anterior tibias slender, not more than 

 half as long as the femora, outer carina with six spines including the terminal one, inner carina with 

 a great number of curved spines which gradualh' increase in length and terminate in an immense 

 curving hook about two-fifths as long as the tibia", anterior tarsi with the first joint slender, curved.

 attenuate in the middle, all the cariucS very finely denticulate, femora with an inner and tibiae with an 

 outer terminal spine; posterior femora and tibiae long, rather slender, of nearly equal length, all the 

 carinas very finely denticulate, fennn-a with an mner terminal spine, tibia- with an inner and outer one.

16. Genus SEVERINIA, Finot 



Severinia. Linot, Ann. Soc. Ent. Belg. Vol. 46, p. 433 (1902). 



Characters, — Body greatly elongate, slender, weakly subspinose in the female. I lead 

 triangular, vertex not produced behind the eyes, occiput obtuse; eyes globose, in the female the apex 

 terminates in a short subcylindrical obtuse spine: ocelli strong, little distant, placed in a triangle, 

 their plane being perptmdicular to the surface on which they are placed, the mferior placed a little below 

 the insertion of the antenna' ; antenna^ of the male simple, of the female unknown. Pronotum elongate, 

 much longer than the anterior coxa, the part posterior to the transverse sulcus slightly more than three 

 times as long as the anterior part, rounded anteriorly, margins denticulate; supracoxal dilation not 

 strong; median longitudinal carina vei \ distinct, the apex being a heart shaped tubercle. Tegmina 

 abbreviate, in the male i caching the sixth abdominal segment, in the female not reaching the third : 

 costal field irregularly reticulate. Wings marked with purplish black. Anterior coxa- not lobate, the base 

 and dorsal margin at the apex not ililated; anterior femora beneath with the internal margin in the 

 female armed with alternately large and small spines, in the male with equal spines, external margin 

 with tour spines, tliscoidal spines four in number, three in a longitudinal series: anterior tibiae beneath 

 with the external margin siiinultjse. Median and posterior femora and tibia carinate above, median and 

 posterior limbs not lobate ; posterior tarsi with the. first two joints slightly longer than the remaining 

 joints together. Supra-anal plate transverse, apex rotundatc; cerci ovate, bioad, fiat and foliate. 



(i) This genus, the type of which has apparently remained unique since described, is clo^^ely related to H^ierochtvt^t : in tact it is difticult to rind 

 any character in the original description to separate it from the latter genus. Ihere exists in the author's mind a strong suspicion that the two are 

 inseparable, but it appears preferable to let the name stand for the present as a valid genus, although the diagnosis contains little in the way of differentia' 

 characters. 



(2; Known only from the female.
