9G GLOSSTNA FTTSCA.— DESCPJPTrON. 



pit, and frontal margins narrowly, shinimei'ing whitish yellow; 

 ocellar spot not, or scarcely darker than frontal stripe ; ocelli 

 large, anterior ocellus the largest. Bases of the vertical bristles 

 united by a more or less conspicuous brown band. Antennse buff; 

 second joint on inside, and distal half or two-thirds of third joint 

 brown ; second joint sometimes entirely brown. Arista buff, 

 second joint dark-brown at base beneath. Palpi buff, upper 

 surface grayish brown, and rather more than apical quarter 

 brown ; the row of short erect black bristles along upper margin 

 very conspicuous.* 



Thorax. — Series of markings on dorsum, as descx'ibed for 

 Gl. palpalis, much reduced and but little conspicuous ; most 

 distinct are the two narrow ad-median stripes in front of the 

 suture, the narrow curved stripe outside these on each side, 

 sometimes with pi'olongation to anterior margin of thorax, and 

 two faint blotches enclosed by the curved stripe, one in front 

 of and one behind the transverse suture ; the small spot on the 

 suture, between the ad-median and the curved stripe on each side 

 more or less distinct ; spot on inner margin of humeral callus 

 usually very faint. Scutellum grayish-brown ; margin and 

 impressed median line buff. 



Abdomen. — The longer harr at the base of the second segment 

 golden-yellow in the middle, dark-brown or black at the sides ; 

 third, fourth, and fifth segments very short ; a pale median stripe 

 wanting, or scarcely visible if at all, but posterior angles and 

 (usually) more or less of extreme hind margiuvS of the third to 

 the sixth segments inclusive yellowish, so that the colour of these 

 segments is obviously due to dark transverse bands, as in the 

 case of species previously described ; seventh segment and 

 hypopygium of ^ clothed with grayish-yellow du.st. 



Legs. — Front femora sometimes more or less infuscated on 

 inner side ; middle femora with a brownish blotch on under side 

 near tip ; solitaiy bristle on upper side of middle femora near the 

 tip, stout and conspicuous ; front tibiie sometimes with dark 

 brown blotch on inside in middle, representing ring sometimes 

 .seen on middle and hind tibiee ; extreme tips of fi'ont and hind 

 tibiae and extreme base of first joint • of front and hind tarsi 

 reddish-brown on under side ; front and hind tibije towaids the 

 tips and first three joiiits of front and hind tarsi clothed beneath 



* In Walker's type (a 9 ) the bristles on the margin of the buccal 

 cavity below tlie vibrissal angle are golden-yellow instead of black ; a trace 

 of this is sometimes seen in other specimens also. .■
