ADSTRO-MALAYAN DIPTERA 457 



NB. I have two specimens from Sorong, New Guinea (May 

 1872, L. M. B'Alberlis) , which resemble C lunaria in every 

 respect (as far as I can discern, because they are indifferently 

 preserved) ; only the lunate hyaline crossband is replaced here 

 by a much broader one (although not quite as broad as that of 

 C. morbida). When Macquart, D. E. II , 3, 245 refers the des- 

 cription of C. larsala Wied. (South America) to a specimen 

 from New Guinea, he probably had such a one before him. 



Calobata morbida c/' 9 , n. sp. Is exceedingly like the preceding 

 species, but differs principally in the coloration of the wings ; the 

 intermediate brown crossband is much narrower, in consequence 

 of which the hyaline interval between it and the apical spot is 

 broader, (as broad as the crossband) ; thus it comes that the 

 end of the second vein is here on hyaline ground, while it is on 

 brown ground in C. lunaria. The antennae are darker than 

 in lunaria (altogether dark brown or black, only the base of 

 the arista reddish) , the hind legs , on the contrary less dark , 

 (the hind femora are reddish-brown , or in some 

 specimens, brownish red, the whole distal third 

 is of a ligther , reddish shade, with an indication 

 of a brownish ring, a Httle before the tip ; at the 

 base of the femora some yellow is visible, but not 

 in all the specimens). The blackish thoracic stripes Toiax of 



Calobata morbida. 



have a different shape^ the lateral ones not being 

 linear, but triangularly expanded in the middle and connected 

 with a blackish pattern on both sides of the thoracic suture. 

 Hab. Buitenzorg, Java {G. B. Ferrari, 1875); Ajer Mantcior 

 and Kaju Tanam , Sumatra (August and Sept. 1878 , Beccari). 

 A dozen specimens. 



Nestima nov. gen. 



Neslima has the characters of Calobata, but is especially di- 

 stinguished by the peculiar structure ' of the metanotum : under 

 the triangular scutellum there is a conical projection of the
