NEW GENERA AND SPECIES 



The genitalia of the male remember by their elongate 

 clubbed app. inf. and by the curved app. sup. those of 

 corripiens. The genitalvalve also is similar, but the penis 

 is more like that of hieroglyphica^ as it consists of two 

 digitiform hairy prominences. 



Body cf 30 mm., forew. 36 mm., hindw. 32 mm., ant. 11 mm. 

 Abd. c/" 15 mm., gr.br. 13 mm., gr.br. 11 mm, 



App. sup. (/ 3 mm. 



Habitat: Columbia. 



One male from Bogota, Columbia, purchased from Don- 

 caster, is in my collection in the Leyden Museum. 



Frotohermes davidi, nov. spec. 



Much resembling P. alhipennis (Wlk.) from India, but 

 larger, with much denser wingnervature and also very dif- 

 ferent in the genitalia of the male. 



Body luteous. Tips of mandibles and the spot between 

 the ocelli, black. Antennae black, the two basal joints 

 luteous, with a brown annulus in the middle. Prothorax 

 with a broad, black streak at each side. Mesothorax with 

 two black spots. Legs luteous to fuscous. 



Wings large and very broad, with yellow nervature, 

 which becomes brown towards the apex and borders ; there 

 are no well-defined pale spots. In the hindwings the yellow 

 nervature occupies only about the half, in the forewings 

 nearly two thirds of the wing. In the latter the postcosta 

 and cubitus inferior with adjoining nervature are fuscous. 

 The crossveins are very numerous and the number of 

 costalveins in the forewing can increase to 46, in the 

 hindwing to 39. 



The gonopoda of the male are yellow. The app. sup. 

 are broadly triangular with rounded tip. The genitalvalve 

 consists of two divergent acute triangular prominences, 

 which are as long as the app. sup. The app. inf. are 

 short, clawlike, with black tips.
