Squama —(Sq.)- The wings of Bombyliidae are characterised by not having cell M3. They are either with or without 4 posterior cells (K5, 2d M2, and. id A:'' 0)2, Cui^Ma Text-fig. 1.—Wing of Bombylius (semidiagrammatic). 0%), usually with a discoidal cell (1st M2), only a few without it, with 2 or 3 submarginal cells (R3 and R4), rarely with only 1, with the second longitudinal vein (R2+3) arising from third longitudinal vein (R4 and R5) either near the base and acutely or a good distance away from base and at right angles, with the vein (R4) between submarginal cells in many cases also arising at right angles from Mx + R5 and there provided with a short stump, with the first and second basal cells (R and 2d M) sometimes equal in length but usually with R longer than 2d M, with the discal cross vein (r-m) either before middle, at middle, or beyond middle of discoidal cell (1st M2), with the first posterior cell (R5) and anal cell (1st A) either open or closed and acute apically and provided with a stalk of variable length, with the axillary.
