482 TIPULID^E. 



The marginal cross-vein (in the four species known to me) is 

 more distal than in Moiu/oma ; and the 1st section of the 2nd 

 longitudinal vein (i. e. that portion up to the origin of the 3rd 

 vein) is shorter than in Monyoma, being not longer than one-third 

 the length of that vein. Upper branch of 4th longitudinal vein 

 nearly straight, or gently curved ; posterior cross-vein distinctly 

 but not much before the fork of the 4th longitudinal vein. (This 

 may be found a variable character, when additional species are 

 discovered.) Remainder of venation and all other characters as 

 in Monyoma.* 



Eanye. Sumatra, India, and Ceylon. 



Bigot's genus Trentepohlia is synonymous with Monyomioides, but 

 was hopelessly uncharacterised (vide p. 447), and it is to be regretted 

 that Dir. Enderlein has attempted to revive it. But for Bigot's 

 mention of M. trtntepolilii as the type species, it would never have 

 been identified.

<S $ . Body wholly yellowish, occasionally a little tinged with 

 brownish, especially on the abdomen, the tip of which is generally 

 blackish. Head greyish, with black hairs. Antennae and palpi 

 more or less dusky, especially the former, which often has the tip 

 of the 1st joint blackish, and sometimes wholly so. Thorax 

 slightly shining, with the merest trace of a dusky median stripe. 

 Abdomen with short, very pale hairs. Legs wholly concolorous. 

 Wings clear, veins distinct; tip of wing blackish, especially along 

 the end of the 2nd longitudinal vein with its upper branch ; the 

 cross-veins in the middle of the wing are also more or less suffused ; 

 the darkening of the wing-tip is distinctly variable, both in extent 

 and intensity. Halteres pale yellow. 



Length 5-6 millim.
