Studies on Tipulidae. 171 



Tliere are two males and one female in the British Museum, 

 likewise from China, with a yellowisli-red thoracic dorsum; the pre- 

 vailing color of the abdomen is reddish-yellow, only tlie first segment, 

 and the posterior margins of the foUowing segments, expanded into 

 triangies, are black; male forceps rufous; legs yellow, tarsi brownish ; 

 a trace of the white ring is visible on them bind tibiae only; wings 

 brown, with a pale yellow crossband, (as described above), only the 

 shade of them much paler. I am strongiy inclined to take even these 

 specimens for a variety of P. fiimiplena.

Ctenophora incunctans "Walk. J. Pr. Lin. Soc. IV, p. 93. — 

 Celebes. 

 There are three specimens in the British Museum. A male and 

 a female have the head, the base of the antennae, the whole thorax, 

 the coxae and the'root of the abdomen reddish-yellow; the male 

 bears the label „type". This must be considered as the true in- 

 cunctans. A female specimen, likewise labelled „type", and bearing 

 Mr. Walker's label „incunctans" has only the diso of the thorax 

 orange-red; coUare, scutel and metanotum are black. I believe 

 Mr. V, d. Wulp was right in describing this as a distinct species 

 {velutina)\ he found a female specimen likewise from Celebes, in 

 the Museum in Leyden. Mr. Walker's specimens have altogether black 

 legs and brown wings; the whitish streaks,, mentioned by him are 

 inconspicuGus. 



7. P. gaudens "Walk. (Celebes). Either this species is variable 

 as to the extent of the black on the abdomen, and of the yellow at the 

 root of the wings, or eise there is more than one, closely allied, species 

 from the same locality. — „Femoribus ochraceis, apice nigris" does 

 not quite agree with a specimen from Celebes which I now have be- 

 fore me; the base of the femora is dark reddish-brown. 



8. P. rubra n. sp. §. Wings subhyaline, uniformly colored 

 with a topazine yellowish - brown ; stigma brown. Body orange-red, 

 except the tip of the abdomen which is black (g forceps and a 

 portion of the upper side of the two preceding segments); front also 

 blackish, but vertex orange. Legs black, except the coxae and the 

 root of the femora, which are reddish; a white ring on the tibiae.
