Stefaniella orientalis n. sp. 



The one peculiar adult was reared from a petiole gall and bore the 

 following data on the label: 



Lepidagathis javanica Bl. Oengaran-Gebirge, altitude 1200 M. 18/IV, 

 '12, DvL. It was also stated that the gall was underscribed. 



The insect is tentatively referred to this genus because in the absence of 

 the female it cannot well be placed elsewhere though the general appearance 

 is quite distinct from 5. falcaria decribed above. 



Male. Length 2 m.M. Antennae extending to the base of the abdomen, rather 

 thickly haired, yellowish brown, yellowish basally, 18 or 19 segments. The flagellate 

 cylindric, with a thick whorl basally of long curved setae, the third and fourth free, the 

 fifth with a length one half greater than its diameter, the terminal segment slightly 

 produced, narrowly conical and with a length one half greater than its diameter. Palpi, 

 first segment broadly oval, the second a little longer and narrowly oval. Mesonotum 

 apparently yellowish, scutellum and postscutellum yellowish, abdomen dark brown, the 

 basal segment whitish, the second and third broadly and the fourth to the sixth narrowly 

 margined posteriorly with whitish, the 7th and 8th whitish. Wings hyaline, costa pale 

 straw, the third vein uniting with the margin at the distal third. Coxae and femora yello- 

 wish, tibiae and tarsi pale straw. Claws long, rather stout, strongly curved, unidentate, 

 the pulvilli nearly as long as the claws, üenitalia, basal clasp segment moderately long, 

 stout, terminal clasp segment long, swollen basally, dorsal plate long, broad, broadly 

 and triangularly emarginate, the lobes broadly triangular, sparsely setose apically, ventral 

 plate short, broad, broadly rounded and sparsely setose apically. 



Type Cecid. A 3098 N. Y. State Museum. 



Lasioptera javanica.

Marcellia 8:123 



Specimens referrable with very little question to this species were record- 

 ed as having been reared from a stem gall on Melothria species like that 

 caused by the above named insect. The data on the label is as follows: 

 Melothria sp., Oengaran-Gebirge, altitude 1400 M., 13/IV, '14, DvL. 



This insect appears to be a typical Lasioptera except that the third and 

 fourth antennal segments are not fused in the manner characteristic of long 

 series of American species. The pupa appears to be unknown and it is therefore 

 characterized in this connection.
