E. hexapla^ but the tibiae are blackish except for a short distance at 

 tip and the tarsi are brown from tip of basitarsi; all tarsi apically 

 darkened ; mesonotum with a heavily brown-pruinose roundish patch 

 behind transverse suture, a band before scutellum, and one at mesal 

 corner of notopleural area. 



Wing fascia beyond tp (fifth from base of wing) extending basad 

 between third and fourth veins, making the band twice as wide at 

 this point; two st-ernopleurals ; one strong posterior and one small 

 anterior notopleural bristle; apical wing spot longer than width of 

 first posterior cell at base of spot; copulatory fork as in figures 74, 



Type. — Holotype, male, U.S.N.M. No. 58302, Philippine Islands : 

 Luzon (Ube Laguna), May 12, 1929, E. C. McGregor collector. 



15. EURYBATA TESSELLATA, new species 



Figure 74, h 



Male and female. — Length, 10 mm. (exclusive of ovipositor in 

 female). Antennae blackish except at base, twice as long as wide; 

 the shining mesofrontal wedge xory rapidly running out into a short 

 point not more than halfway to ocellus; fore femora blackish except 

 short distance at base ; fore tibiae a little brownish apically ; all tai-si 

 light brown apically; mesonotum without distinctly set-off pruinose 

 areas; wings with the transverse fasciae, especially in middle of wing, 

 broken into a series of alternating squarish blotches; a hyaline spot 

 anterior to tp lying directly posterior to a brown blotch in submarginal 

 cell; marginal cell wholly brown; apical wing spot indistinct; two 

 subequal notopleural bristles ; two sternopleurals ; copulatory fork of 

 male as in figure 74, h. 



Types. — Holotype, male, U.S.N.M. No. 58303, Philippine Islands: 

 Mindanao (Surigao), Baker collector; allotype, female. Island of

CROSA, new genus 



Genotype. — Euryhata semilauta Osten-Sacken. 



Distinguished from related genera as in the foregoing key, as well 

 as by the following characters: Mesofrons (fig. 74, c) wholly dull, 

 vertical in front, not projecting, paraf rentals ending bluntly; ocelli 

 well f oreward ; one dorsocentral bristle ; pterostigma very small ; ab- 

 domen wholly pruinose ; male fore femora with many long loose hairs 

 on basal ventral side. 



It is possible that with the exception of the preceding three species 

 all those heretofore included in Euryhata should find their place here.
