strong bristly hairs. Pubescence in Toxophora and Lepiclophora mainly of a scaly 

 nature, and the males of Lejndophora and Thevenetimyia with splayed out lateral 

 tufts of scaly feathers which apparently mimic the anal tufts of Sesiidce (Lepidoptera). 



Legs with strong bristles beneath the hind femora (except in Fdimus, and only 

 slight in Thevenetimj/ia) but limited to the ajiical part in Toxophora and occurring 

 in the male only of Cyllenia mandata, and with conspicuous bristles or spicules on 

 the hind tibiae (except in Edinius and its allies). 



Wings with the radial and cubital veins diverging at an acute angle almost 

 opposite the base of the discal cell and consequently far before the discal cross-vein, 

 and this cross-vein uxjright and placed slightly or considerably beyond the middle of 

 the discal cell ; radial vein varying from not being looped at all before its end 

 (Toxophora) to being exceedingly looped {Lepidoidiora) ; cubital fork short and 

 wide open ; submarginal cells two or three ; posterior cells three or four ; anal cell 

 closed and petiolate in Toxophora. and closed at the wingmargin in Lepidophora, 

 but open in the other genera ; alula and hind angle of the wing well developed in 

 Toxophora, and Lepndojthora, but weak in Tomomyza, and absent in Amictus and 

 Cyllenia* Squama; usually with only a slight fringe, but in Toxophora with a 

 remarkably long rigid one. 



Some of the species of Lc2ndop1iora. and Thevenetimyia seem to mimic 

 SesiidK (Lepidoptera). 



The Toxophorinoi were suggested as a separate subfamily by Schiner in 

 1868 (Novara Keise, Dipt., 116) for Toxophora, Eelimus, Lepidophora, 

 Enicmicura, Systropus, and Doliehomyia, upon the characters of three 

 posterior cells, the structure of the antennse, the usually humped thorax, 

 and the usually very long and narrow abdomen. Of these genera 

 Systropus and Doliehomyia are now separated off into the subfamily 

 Systropi^ice, and Eniconeura is synonymous with Toxophora. Lepidophora 

 has four posterior cells, and in many ways is so much allied to Toxophora, 

 especially in the remarkable development of the prothorax, that at one 

 time I was inclined to restrict the Toxophorince to these two genera, but 

 when I tried to define the Lomatince I came to the opinion that Amictus 

 and Cyllenia through their tubular elongate abdomen, their drooping head 

 and abdomen, their long proboscis (in Amictus), and their unusual bristliness, 

 had more in common with the Toxop)horinm than with the Lomatinw, 

 and then I came to the conclusion that Eelimus (with its allied genera) 

 and Tomomyza (from its affinity to Cyllenia) must also join them. 

 Eelimus and Thevenetimyia differ in many ways from the subfamily 

 characters, as their thorax is not humped nor the abdomen so much 

 drooped, while the bristles are reduced to about two prsesutural, and the basal 

 joint of the antennae is only moderately long. Tomomyza has an Anthrax- 

 like appearance and a short proboscis, but does not readily associate 

 with the Lomatince. Like Osten Sacken I must leave further develop- 

 ments of the grouping of these genera to the monographer.

1 (2) Prothorax exceedingly developed so as to form a dorsal shield 

 between the mesonotum and the head. Anal cell closed. 



* Bigot's coUection contained a single specimen each of Edinms Quedenfeldti and E. venosus ; E. Queclenfddti 

 has a fairly well-developed alula and hind angle, but in E. ve^wava both are entirely absent.
