138 INSECUTOR INSClTi/E MENSTRUUS 



small pale greenish recurved hook ; palpi apparently 4-segmented, black. 

 Antennae dark brown. Head light silvery gray with blackish reflections ; 

 a fleshy elongate lobe, black in color, on the vertex, extending cephalad 

 to near the base of the antenns. 



Cervical sclerites and the pronotum dark browTi. Mesonotum, prae- 

 scutum with a small median brown knob on the cephalic margin. Lobes 

 of the scutum dark brown, this color produced anteriorly in a long stripe 

 which continues along the praescutum to the knob described above. 

 Prasscutum with a pale browTi median stripe which continues back to the 

 transverse suture ; scutum with the median space pale. Scutellum pale 

 yellowish, except a brown mark on the anterior part on either side, this 

 being an elongation of the caudal lobe. Postnotum yellow with a broad 

 transverse brown band. Pleurae with two conspicuous transverse stripes, 

 the upper one broadest, beginning above the fore coxae, continuing back- 

 ward, above the halter, to the postnotum where it fuses with the trans- 

 verse brown band described above ; a narrower brown band begins on 

 the mesonotum just before the mesocoxae and continues to the abdomen. 

 Halleres dark brown. Legs, coxae, and trochanters brownish yellow, 

 femora light brown, tibiae and tarsi brownish yellow. Wing, veins dark 

 brown, cells C and Sc light brown, remainder of wings hyaline ; narrow 

 pale brown seams along Rs and the cross-veins and deflections of veins ; 

 there are three dark brown marks in cell Sc, the first at the base, the 

 third at the tip of vein 5c, the second being midway between the other 

 two and containing a supernumerary cross-vein as is usual in this genus. 

 Venation, Sc ending just beyond the origin of Rs ; cross-vein Scz not 

 evident ; Rs long, about twice as long as the deflection of R4+5 ', cell 

 first M2 very long, narrow, quadrangular or nearly so, the basal deflection 

 of Cui at its base; the veins issuing from cell first Mz very short. 



Abdomen, tergites dark brown ; basal three or four stemites yellowish 

 darkening into browTi on the terminal segments. 



Hololype, d", Pettit Banks, Philippine Islands, October 23. 1912 

 (Dr. Ludlow). Paratypes, 7 d' , with the type, taken at 1 p. m. ; 4 c? , 

 type locality, between daylight and dark on October 22, 1912. 



This species is closest to G'. nolala Meij. of Java in its striped pleurae ; 

 it differs in the color of the thorax, wings, legs, and structural characters. 



A key to the Oriental species of Geranowyia is given in Brunelti's 

 Fauna of British India, p. 388, 1912. The East Indian species are 

 considerrd by de Meijere in Tijdschrift voor Entomologie, vol. 54, p. 31,
