Dicranota nipponica sp. n. 



Antennee with twelve segments, the temiinal segment small; meso- 

 notal praescutum grayish buff, with three dark brown stripes, the 

 median one of which is split by a capillary line of the ground color; 

 male hypopygium at the outer angle produced caudad into a lobe. 



Male — Length, 7.5 mm.; wing, 8.7 mm. 



Rostrtmi and palpi brown. Antennas dark brownish black, the 

 flagellar segments with a conspicuous erect white pubescence in addition 

 to the verticils; but ten flagellar segments are evident, the last much 

 smaller than the penultimate; first flagellar segment long clavate, much 

 longer than those following. Head brownish gray, very narrowly 

 clearer gray along the inner margins of the eyes. 



Thorax light grayish buff, the praescutum with three dark brown 

 stripes of which the intermediate one is distinctly split by a capillary 

 vitta of the ground color; scutal lobes gray marked with pale brown; 

 scutellum, postnotum and pleura light gray. Halteres pale brown, 

 brighter at the base. Legs with the coxae light gray, more yellowish 

 apically; trochanters dull yellow, the outer margins blackened; femora 

 brownish yellow, brighter at the base, the tips dark brown; tibiae dark 

 brown, the tips black; tarsi dark brownish black. Wings with a pale 

 gray tinge; stigma elongate, brown, extending from r to the tip of ^1+2; 

 veins dark brownish black, the veins at the wing base a little paler. 

 Venation: Rs very short, strongly angulated to almost square at its 

 origin, slightly spurred; i^2+3+4 short, about equal to r-m; apical fusion 

 of Ri with Ri slight; cell 1st Mi open, cell Mi present. 



Abdomen dark brownish gray, the tergites very narrowly margined 

 caudally with paler gray; stemites similarly margined with yellowish 

 gray and with an indistinct broken median yellowish stripe. Male 

 hypopygium with the outer angle of the pleurites extended caudad into 

 a blunt hairy lobe; two pleural appendages, the inner one of which is 

 curved, flattened and expanded distally, not conspicuously armed with
