 of the abdomen. Abdomen beneath testaceous ; basal segment entirely black, the following segments 

 triangnlurly blackish on each side at the base, the last two lateral lobes spotted with black. Tegulie and 

 wings hyaline, with brown nervures ; costal nervures and inner marginal nervures testaceous."'

Head, pronotum, and mesonotum tawny-ochraceous ; head with some black spots on fi'ont and a 

 broken transverse black fascia between the ej-es ; pronotum with two black discal spots, the anterior one 

 longitudinal, the posterior one transverse; mesonotum with four black spots on anterior margin, the 

 two central ones smallest, a central longitudinal line not reachmg anterior margin, and a small spot in 

 front of each anterior angle of the basal cruciform elevation ; abdomen black, tympanal coverings, lateral 

 posterior margins of the first segment, posterior margins of the second, third, and fourth segments, and 

 a large spot on each side of the apical segment ochraceous. Head beneath, sternum, and opercula 

 ochraceous ; a spot on each side of anterior margin and the central sulcation to face, a transverse spot 

 between face and eyes, and the interior area of opercula black; abdomen beneath dark castaneous. 

 Tegmina pale hyaline, costal membrane and venation brownish-ochraceous, transverse vein at base of 

 second ulnar area, and the transverse veins at bases of apical areas faintly infuscated, faint fuscous 

 spots on lower margins of second and third ulnar areas, and a small double series near the apices of the 

 longitudinal veins to apical areas. 



The pronotum is considerably and angularly produced on each side, the rostrum passes the posterior 

 coxae, and extends to near the inner angles of the opercula. 



y<ir. a. Tegmina with all the fuscous markings darkened and enlarged, and with the addition of the 

 basal cell, a spot in centre and at apex of radial area, and a spot near base of fourth ulnar area, also pale 

 fuscous. 



Long. excl. tegm. 23 millim. Exp. tegm. 70 millim. Exp. pronot. angl. 12 to 12^ millim. 

 Hab.— Continental India ; Karwar, Canara, Trevandrum (Calc. Mus. and coll. Dist.). 



The varietal form described above was collected at Trevandrum. The species is 

 evidently a continental one, and its habitat is now for the tirst time published, as Walker 

 had no knowledge of the locality from which the British Museum specuueu was derived. 



* I have taken these dimensious from the figure, as Mr. Kirb.v has appended none to his diagnosis.
