228 C. R. Osten Sacken: Diptera 



(Celebes), ot which I have specimens before me is a closely alHed, if 

 not the same species; the wings are exactly the same, and the body 

 likewise, as far as the very po.or condition of my specimens of stellata 

 allows a comparison. Mr, Walker had determined the latter specimens 

 T. ampUssima, which means I suppose T. amplipennis Wk. J. Pr. L. 

 Soc. IV, 159 (Celebes), a species described on the same page as 

 T. stellipennis, and marked as occuring in the Philippine Islands in 

 Mr. Walker's Synopsis (J. Pr. Lin. Soc. IX, 27). But ampUssima 

 is said to have a „bare arista", while the arista is distinctly plumose 

 in my specimens of T. stellata, as well as in T. stellipennis. But 

 Mr. Walker had also called bare the arista of his Sophira punctifera 

 (which is again nothing eise but his own T. stellipennis), and never- 

 theless his own type, which I saw in the Br. Mus., has a distinctly 

 plumose arista. (Compare my Enumer. etc. 71). With JEutreta Lw 

 these species (whether there are one or several I do not decide) have 

 the broad wings, dotted with white, in common; but their scutellum 

 has six, instead of four, bristles and the third vein is bristly. 



Trypeta (subg. Tephritis)] a single, damaged male. Small 

 species, the design on the wings very like that of the european and 

 north-american species of the group, without being exactly like any 

 of them. 



Trypeta Cassandra n. sp. $. Venation like Ceratitis; 

 body hlack shining; humeri and anterior portion of the scutellum 

 pale-yellow; abdominal segments alternately black and gray; 

 ivings banded with brown. Length 6 — 7 mm. 



Face pale-yellow, hardly excavated in the profile; cheeks brownish 

 under the eyes; front yellow, brownish -ferruginous in the middle; an- 

 tennae yellowish-red, reaching down to about half the face; arista plu- 

 mose; occiput very tumid behind the eyes, pale yellow; its upper, flat 

 portion brownish. Thorax black, shining; humeri, a short band behind 

 them, across the mesopleura, the metapleura, the lateral callus of the 

 metanotum, and the anterior part of the scutellum, pale yellow. Ab- 

 domen: first. Segment gray, opaque; its anterior margin black; second 

 Segment, black, brownish pollinosej the third gray, like the first; the 

 fourth black; the gray portions are clothed with a short whitish pu- 

 bescence. Halteres: stem reddish, knob brownish. Legs (only the front 

 pair is extant) reddish -yellow, with black bristles. Wings hyaline, 

 banded with brown: the basal crossband fills the second costal cell and 

 reaches the posterior margin at the axillary excision; a second band 

 forms an arch, which begins at the apex, runs along the costa, stopping
