268 On new and little-known Tipulide. 
oblique. Se; incomplete. Rs equal in length to Rg, a little 
shorter than R,,3, which in its turn is a little shorter than 
the stigma. Cell M, sessile. Cell 1st M, of the normal 
elongate shape. Cu, fused with M for some distance, but 
leaving it again before the fork. Cell Cu, at tip not much 
narrower than cell M3. Ha/teres light brownish. 
Length of thorax and abdomen 14°56 mm.; wing 14 mm. 
Kammotu, 10. iv. 1910, 1 ¢ (1. Nitobe). 
Although this specimen lacks the head, it seems worth 
while to describe it, owing to several peculiarities of colora- 
tion and one of venation—the fusion of Cu, with M. P. pal- 
loris, Coq., has a very similar wing, but in that species the 
costal cell is dark and the thorax is distinctly striped, the 
lateral stripes having a velvet-black spot on each side of their 
anteriorends. P.immaculata, Wulp, has not been adequately 
described, but apparently differs in being of smaller size and 
in having the legs dark and last two abdominal segments 
black. 
Pachyrrhina sinensis, sp. n. 
A female specimen in the British Museum from N. China 
(Fortune) representing another new species allied to P. palloris, 
Coq., and P. formosensis may be described here. 
Head dull orange ; asmall, triangular, shining, light brown 
spot on the vertex; rostrum shining brown, somewhat 
darker above. Palpi brownish. Scape of antenne orange 
(flagellum missing). Thorax: pronotum dull, orange in 
the middle, brown at the sides. Mesothorax with the entire 
surface slightly shining, the postnotum moreso. Prescutum 
brownish ochreous, with four darker brown stripes, the 
middle pair just connected in front of the suture, rather 
lighter in colour and less well-defined than the lateral pair. 
Scutum rather dark brownish, lighter in the middle, a velvet- 
black streak on each lateral margin, just in front of the 
wing-base, continued narrowly nearly halfway along the 
suture. Seutellum yellowish brown. Postnotum pale in the 
middle, brown at the sides. Pleurse mainly pale ochreous ; a 
rather broad but ill-defined brown stripe runs from the lateral 
stripe of the prescutum to the middle coxe. Abdomen 
moderately shining, brownish ochreous; first segment dark 
above; segments 2-6 with large blackish-brown triangles on 
the posterior margin, second segment also with a brown spot 
near the base; hind margins of segments 7 and 8 narrowly 
brownish; blackish lateral stripes as in P. formosensis, 
except that they are rather broadly interrupted at the base of
