E. 2 about three times longer than its petiole, occasionally som>^what longer. Cell 

 E 3 a little longer than R 4 + 5. Cell 1st M 2 about two times longer than 

 broad. Petiole of cell M 1 as long as the cell or somewhat shorter. Ascending 

 portion of Cu 1 joining cell 1st M 2 in its middle, rarely more basad. A 1 

 curved at the apex, which is opposite the apex of Sc 1. A 2 curved at the apex, 

 usually with a spur directed obliqu.ely forward some distance before the tip. 

 Halteres rather long, pale testaceous, the club infuscated. Ovipositor slightly 

 curved, iipper valves straight, much shorter than the lower ones, narrowly trun- 

 cate at apex. Legs testaceous with the apex of femora and tibia3 fuscous, or 

 entirely fuscous except the coxse, trochanters, and base of femora, which are 

 always testaceous. 



The specimens communicated by Verrall bear the labels Sutton 

 and Dovedale. He wrote that he had found them on the damp surface 

 of overhanging rocks. They are not in good condition, and the apex of 

 the abdomen being destroyed in the only male, I am unable to give any 

 information about the structure and coloiu' of the propygium, but I 

 suppose British Dipterists can supplement the description from better 

 preserved material. 



In most wings the second anal vein makes a sudden hitch toward 

 the first anal vein some distance before its tip, and is at this point pro- 

 vided with a spur or stump of a vein directed obliquely toward the hind 

 margin of ths wing. When snch is the case there is a fuscous spot at 

 this point, a very unusual place for an incomplete vein in the Tipulidas, 

 and foreshadowing the structure of the second anal vein in the South 

 African genus Podoneura, Bergr. This genus is placed in the Limno- 

 pliUirite by I^Teedham, who finds its venation " aberrant " in several 

 respects ; aiid so it is if Podoneura is placed there, but it belongs to the 

 Eriojiterinm, as I clearly stated in my description. Its venation is very 

 similar to that of the allied genera, Sympleda, Meig., and Psilooonopa, 

 Zett. {Trimicra, O.S.), the only aberrant character being the furcated 

 second anal vein. 



I seize the opportunity to correct the synonymy of two genera of 

 Tipulidag. Meigen founded his genus Cfenoj'hora on fovir species 

 without indicating the type. In his paper, " The type-species of the 

 North American genera of Dijitera" (Proc. XJ. S. Nat. Mus., xxxvii, 

 pp. 499 — 647), Coquillett cites as type of this genus, Tipula atrata, L., 

 " by designation of Latreille, Consider. GTeneral., 1810, p. 442." For 

 the genus hitherto called Gtenopliora he substitutes the new name 

 Phoroctenia. The fact is, however, that Latreille, as early as 1805 

 (Hist. Nat. Crust. Ins., xiv, p. 286), singled out « /raf a, L. {iclineumonea, 

 De G.), foimding the genus Tanyptera w^on it. Atrata was thus for 

 the future precluded from the possibility of being considered the type
