498 TIPULID^E. 



short pubescence. Thorax of male from yellowish grey to rather 

 dark brownish yellow ; a rather broad brown median line, with a 

 row of about nine or ten small dark brown spots on each side of 

 it ; a narrow median line is present on the concolorous scutellum, 

 which is furnished with moderately long golden yellow hairs on 

 the posterior margin ; posterior corners of dorsutn with a few 

 similar yellow hairs and a few are placed in front of the scu- 

 tellum ; a less distinct grey stripe on each side of the median one, 

 beginning some distance behind the shoulder and interrupted at 

 the suture, behind which it takes the form of a spot and a pointed 

 elongated stripe which attains the posterior margin ; on the rest 

 of the dorsurn and towards and on the sides (which are con- 

 colorous) are small spots and marks irregularly placed ; metanotum 

 rather more grey than yellow, with traces of a dark median line. 

 In the female, on each side of the narrow median thoracic stripe 

 is a close series of irregularly placed small brown spots, two or 

 three abreast, reaching from the anterior margin to the suture ; 

 there is also a patch of similar spots towards each side, in front 

 of the wing. Abdomen yellowish or brownish yellow, the segments 

 clearly emarginated, with short yellow hairs at the sides ; a narrow 

 black stripe often runs along each side of the dorsuin ; belly 

 yellowish. Genitalia of male consisting of an upper plate, a pair 

 of thick brown claspers marked with small brown spots and 

 bearing golden-yellow hairs, terminating each in a bifid yellow 

 claw ; there is also a pair of internal spine-like yellow organs. 

 In the female the abdomen is darker brown, the ovipositor reddish 

 yellow. Legs uniformly yellow, with distinct yellow pubescence ; 

 claws black. Wings yellowish grey. Auxiliary vein ending a little 

 before tip of 1st longitudinal vein, both being distinctly beyond 

 the middle of the wing; the 2nd vein originates much before 

 middle of wing, forking in a peculiar manner just below tip of 

 1st vein ; the upper branch apparently springs at a right angle 

 from the lower one (which latter is in a straight line with the 

 prsefurca), thus having the appearance of a cross-vein, then turns 

 suddenly outward, running parallel with the lower branch ; prae- 

 furca longer than upper branch, but distinctly shorter than lower 

 one ; marginal cross-vein very oblique, uniting the 1st vein (at a 

 little before its tip) with the angle made by the upper branch of 

 the 2nd vein ; basal portion of 3rd vein obliquely placed, straight 

 in itself, appearing almost as a cross-vein, nearly twice as long as 

 anterior cross-vein, which latter is also very abnormally placed, 

 being distinctly beyond the discal cell ; discal cell cylindro-conical ; 

 anterior branch of 4th vein forked half-way between the discal 

 cell and wing-margin, the branches parallel, as are all the veins, 

 practically, with the exception of the branches of the 2nd vein, 

 which distinctly diverge at their extremities ; discal cell rather 

 more than half as long as the 3rd and 4th posterior cells, both of 

 which are equal in length ; posterior cross-vein placed at the first 

 third of the discal cell. In colouring the anterior margin of the 

 wing is more or less broadly brown, but the pattern varies in detail ;
