4 MEGISTOCERA FUSCANA. 



proportionately very sliort. The wings pure hyaline, even 

 along the costa, and more than twice as long as the ab- 

 domen ; the veins and the very distinct stigma are tes- 

 taceous. The neuration agrees chiefly with that of Tipula 

 and Ctenopliora ; the upper basal cell is longer than the 

 two others; the middle basal cell does not quite reach 

 the discal cell, but is separated from it by a small pedi- 

 cle ; the two subcostal cells are large , the inner one some- 

 what triangular, the cubital cell is also broad, especially 

 at its base ; the discal cell on the contrary is very small , 

 trapezoidal ; the first posterior cell is narrow in the mid- 

 dle , in consequence of a sinuosity of the longitudinal veins 

 which limit it ; the axillar vein is very short *).

This species seems to be very common in the Suuda 

 Islands for it occurs in almost every collection , contain- 

 ing Tipulidae, received from there. Besides the many 

 Javanese specimens, existing in the Leyden Museum or 

 in my possession , I have seen specimens of it from Su- 

 matra (v. Lansberge) , from Gorontalo (v. Rosenberg) and 

 from Obi (Bernstein). 



Most of the specimens , which I examined , exactly agree 

 with the description of T. castanea Macq., which must be 

 considered merely as a variety of T. umhrina. The an- 

 tennae are just as Macquart describes them. According 

 to him, the difference principally exists in the absence of 

 the brown stripe on the metanotum and of the white 

 transverse band on the wings. In fact there are only a
