prominent basal tubercles of first segment very well developed; 

 punctulate and pubescent like back of mesonotum, but the 

 first two segments clothed on sides with long, erect, whitish 

 hairs. First segment entirely reddish, with less-distinct, dark- 

 ish, longitudinal middle stripe; second segment reddish at base, 

 yellowish on more than its apical half, with less-distinct middle 

 stripe, and with no black spots at sides; third, fourth, and fifth 

 segments entirely reddish, with no black spots on sides, with only 

 a narrow and complete, black longitudinal stripe in the middle; 

 venter very concave; reddish, with brown apical sternites. 

 Segmentation distinct; sixth segment not visible. Ovipositor 

 reddish, very much swollen at base. Legs entirely reddish, 

 with pale pubescence ; tibiae paler, base of tarsi whitish ; middle 

 tibise with a strong black spur. 



Wings (Plate II, fig. 3) shorter than body, shining and 

 iridescent ; veins reddish ; second longitudinal vein straight ; last 

 portions of third and the fourth parallel, the latter less curved 

 at base; small cross vein placed beyond middle of discoidal 

 cell. The pattern consists of a yellowish and broad, complete 

 costal border, comprising even costal cells and extending below 

 to third vein ; in first posterior cell this border extends below 

 third vein to reach middle of cell and is more intensively dark; 

 this darker, but less-sharply defined, apical spot continued below 

 with a darkish shade, passing over fourth vein int^upper part of 

 second posterior cell. Stigma not darker; first basal cell dark- 

 ened above second. Yellowish anal stripe broad, but not ex- 

 tending to hind border of wing. Second basal cell rather broad. 



20. Mellesis bioculata sp. nov. Plate II, fig. 4. 



Very distinct from all the other species on account of the 

 single hypopleural spot and the peculiar wing pattern. 



Luzon, Laguna Province, Mount Maquiling (Baker). Type 

 in Professor Baker's collection. 



Male. — Length of body, 10 millimeters; of wing, 8.5. Head 

 as in the preceding species, but frons distinctly shorter and 

 broader, being about as long as broad; of the antennas there 

 is only the first joint, which is elongate and yellowish; black 

 facial spots much smaller and rounded; cephalic bristles black, 

 but it seems that the lower orbitals are very much less developed, 

 only the first pair being distinguishable. 



Mesonotum distinctly narrower; entirely reddish on the back, 

 with three very narrow, blackish longitudinal stripes and two
