transverse sensoria. Prothorax bears 2 longitudinal dusky bands. Thoracic lobes 

 and scutellum black. On abdominal segments 2, 3, 4 and 7 occur on each a pair of 

 dusky blunt tubercles on the sides. Cornicles dusky, much widened basally and 

 constricted in the centre. Tarsi and apex of tibiae black, rest of legs pale. Wings 

 large, second fork of third discoidal midway between first fork and wing apex. Cauda 

 and anal plate pale, former globular and beset heavily with spines, latter emarginate. 

 Apical margin of seventh abdominal segment dusky. Beak as in the oviparous 

 female. 



The male is immediately recognizable from the winged viviparous 

 female both by its smaller size and by the noticeable black thoracic 

 lobes. During October 1914, the sexes predominated over the aga- 

 mous forms and in the first half of November oviposition was in prog- 

 ress.

According to Professor Wilson's key of the Callipterini {Can. Ent.y 

 XLII, 8, August 1910), this species runs either to Euceraphis Walker, 

 or to Eucallipterus Schouteden. The broadened base of the cornicles 

 and the cleft anal plate are indications of the latter genus, while the 

 strong frontal tubercles and the lack of auxiliary ocellus-like tubercles 

 on the forehead appear to indicate the former. On the whole I am 

 inclined to place the species in the genus Eucallipterus. 



Myzocallis pasanim sp. nov. 



Winged viviparous female. — General color pale green mottled with patches of darker 

 green. Antennae sUghtly longer than the body, fine, hyaline, situated on moderate- 

 sized frontal tubercles; articulations black. Joint III bears on its enlarged basal 

 sixth 2 or 3 circular sensoria. Joint I, shghtly gibbous on its inner side. Eyes dark 

 red. Thoracic lobes and scutellum greenish-brown. Legs very pale green, extreme 

 base of all tibise and tarsi wholly black. Stigma pale green; at the base and apex are 

 ill-defined brown areas. Immediate bases of first and second discoidal and of stig- 

 matic vein clouded briefly brownish. Stigmatic vein visible for its enth'e length. 

 Mesothorax bears a pair of short conical tubercles. On abdominal segments 1 and 2 

 occur on each a pair of hyaline acutely conical tubercles, all four of which bear 3 spines.
