506 BOMBYLID.E 



LOMATINiE. 



Prsefurca ending (as in Bomhylincc) almost opposite the base of the 

 discal cell. Antennae approximated at the base. Proboscis usually short. 

 Abdomen rather oblong but not cylindrical. 



Head hardly transverse, as broad as or rather narrower than the thorax, never 

 de])re,s.sed, but fitted closely on the thorax. Face usually and often considerably 

 produced over the large or long narrow mouth-opening. Frons large, almost as in 

 Anthracifiw. Occiput rather or considerably inflated and not bearing any strong- 

 bristles. Proboscis usually short and thick, with rather large sucker-flaps, but 

 sometimes porrect and long though hardly so conspicuously as in the liombj/lind'. 

 Eyes of the male very much ai^proximated or even touching, and often with an 

 indentation at the middle of the hindmargin which indicates the commencement 

 of an impressed line bisecting the eyes transversely. Antennae approximated at 

 the base, but not always closely so (Lrmiatin) and sometimes wddely separated 

 (Apha'hantus, Epacmus) ; basal joint only moderately long, and often thick ; style 

 practically absent. 



Thorax not humjjed nor with the prothorax unusually developed ; mesonotum 

 usually with two or three prassutural bristles on each side, and often with postalar 

 bristles, but without any dorso-central or prothoracic bristles, and sometimes 

 (Comptosia) without any bristles, Scutellum large, with the disc flat, and the 

 broadly rounded margin without any strong bristles. 



Abdomen longer than broad, rather flattened, rather oblong, never broad or round 

 or globular (rather conical in Antouia), and never in the least tubular and bare as in 

 >Si/>itropince, not depressed at the base nor drooping, and without any bristly 

 pubescence. 



Legs without spines beneath the femora or with only a few slight ones, but the 

 tibiaB with spicules. 



Wings (fig, 293) with the radial and cubital veins diverging from the short 

 pnefurca at a very acute angle almost opi^osite the base of the discal cell and conse- 

 (luently far before the discal cross-vein ; subcostal vein rather long ; cubital fork 

 usually wide oj^en as in Brnnhylius ; cubital vein always forked, and the submarginal 

 cells two or three • radial vein almost always strongly looped a little before its end 

 and then curved up so that it ends rectangularly or even recurved into the costa ; 

 discal cross-vein usually placed near the end of the discal cell, and often sloping ; 

 posterior cells four, the first one either open or closed ; anal cell ojien (closed in 

 Pivrachthes). 



The Lomatinm are dealt with here in a more restricted sense than 

 heretofore, as the bristly species which have a tubular abdomen [Tomomyza, 

 Amictus (including Tldi^ysomyza), and Cyllcnia] have been relegated to the 

 Toxophorinm. The subfamily may now be distinguished from the Toxo- 

 2'>horinm by the rather oblong flattened abdomen, by the absence of bristles 

 or bristly hairs on the disc of the thorax or on the abdomen, by the thorax 

 not being humped and the head and abdomen not depressed, by the 

 comparative absence of scaly pubescence, and usually by the shorter 

 proboscis and basal joint of antennse. They hardly require comparison 

 with the Systropince, and the short prsefurca and position and style of 

 the divergence between the radial and cubital veins at once distinguish 

 them from the Anthracince, but it is difficult to draw a fixed line 

 between them and the Bomhylinm. The most obvious distinctions from
