margin, extending from the radix to abont tlie length of the snbmarginal vein. 

 Hind -wings: length -75 mm., breadth -14 mm. Neuratiou reaching the 

 middle of tl;e wing. 



Legs. — Fore leg : femnr half as long again as coxa. Tibia not quite half 

 (4 : 9) the femur. Along the inner (anterior) ventral half of the surface of the 

 tibia six of the bristles (none of which are on the edae) are stouter; 

 3-4 bristles along the ventral edae. Apical ventral angle produced into a 

 short tooth; upper apical aT)gle posteriorly with bidentate process — thelovver 

 tooth curved and longer. Anteiiorly along the middle of the 1st tarsal joint 

 are ;> short stout bristles, and one at the anteroventral angle. Joints 2-4 bear 

 anteriorlv 1 similar bristle at the ventral angle, and another above at the 

 middle of the apical suture. Tarsal joints in ratio 3:2:2:2:5. Mid leg : 

 the first tarsal joint is about ^ longer than the 2nd. Hind leg : coxa as long 

 as femur, and both J longer tlian the tibia, which bears posteriorly 5-6 spinose 

 and 3-4 thinner bristles. Tarsal joints in ratio 42 : 27 : 23 : 15 : 36. In all 

 five joints the postero-ventral edge is broadened out and the thin chitin deeply 

 fraved, giving the wiiole tarsus a feathered appe irance. 



Abdomeji. — Tergites 1-4 are medianly salient and shortl3' notched 

 posteriorly. Tergi'e 5 is entire, but there is a clear nnchitinized line from 

 the middle ot the hind marj^in, reaching anteriorly to about |. Tergite 6 is 

 deeply angularly emarginate posteriorly, and nearly divided into two quadri- 

 lateral sclerites, which are connected only by a narrow, almost linear, part of 

 the membrane of the segment. Spiracle moderate, suboval, and somewhat 

 angled antero-ventrally. Eiich sclerite bears 10-20 bristles. The setigerons 

 process (stylet) is much longer (5 : 3) than broad. It is bluntly and broadly 

 truncate, and bears three of the usual four hairs in a transverse apical row ; 

 the fourth is placed on the ventral edge. Ovipositor: measured along tiie 

 ventral edue the abdomen and the ovipositor are of equal length. The 

 Atli :!.ternite vomeriform in profile, its elongate apex reaching the tip of 

 the stylet, or just beyond. 



Length (body) 1*8 mm., alar expanse 3'3 mm. Length of ovipositor '8 mm.

Note. — The light colour of the material on which this description 

 is based may be due, in part, to fading in alcohol, in which the speci- 

 •nens have been for nearly six years. The specific name refers to the 

 fringed appearance of the hind tarsus.

In June of last year Mr. Hugh Main obtained from a sand-pit near 

 Shanklin, I.W., the pseudochrysalis of a Meloid beetle, which in the 

 autumn produced Meloe brrcicoUis. Being myself at Slianklin in April,
