biowiiisli liiiul til)ii\! covered witli uniform dark browu 

 pubescence, the pale rin^ being on the integument only ; 

 in nivttcincla the sette, as well as the integument, are pale. 

 G. Joniiusa, Hutton, is represented in tiie writer's collection 

 by a male; it is a very diHerent Hy, with the tibial ring ill- 

 defined, broad, and orange-} cllow in colour. 



Tricyphona novce-:ela?idi(e, sp. n. 



Oeneral coloration obscure yellowish brown ; mesouotal 

 pra^scutum with four narrow dark brown strip s; wings 

 with a brown tinge, the stigma a little darker ; cell /^2 lo"g- 

 petiolate ; cell H^ short-petiolate ; cell 1st M^ closed ; cell 

 Ml sessile or very short-petiolate. 



Male. — Length 6 mm.; wing 8G mm. 



Rostrum and palpi dark brown. Antennae IG-segmented, 

 the scapal segments pale brown ; flagellum black ; Hagellar 

 segments oval. Head dark brown with a sparse bloom, 

 leaving blotches of the ground-colour exposed. 



Mesouotal prjescutum liglit yellowish brown with four 

 conspicuous dark brown stripes, the intermediate pair 

 separated from one another by a line of the ground-colour 

 that is nearly one-half the width of either stripe ; scutum 

 brown, indistinctly greyish medially ; scutellura and post- 

 notum pale brown with an indistinct j)ruiuosity. Pleura 

 brown with a sparse, microscopic, appressed pubescence that 

 appears like a pruinosity ; a narrow, dark brown, dorsal stripe 

 extending from the propleura to ventrad of the wing-root, 

 lialteres pale, the base of the stem yellow, the knobs infus- 

 cated. ]jfgs with the coxre obscure yellow^, infuscated 

 basally ; trochanters obscure yellow; femora pale brown, 

 the tips scarcely darkened ; tibiae and metatarsi pale brown, 

 the tips narrowly darker brown ; remainder of the tarsi 

 dark brown. Wings with a brown tinge ; cells C and iic 

 more satuiated ; stigma darker brown, but its limits 111- 

 ilefined ; veins dark brown. Venation : Sc2 before the 

 origin of Rs a distance approximately as long as cell \st Mg ; 

 Rs strongly arcuated at origin ; R^j^z elongate, the outer 

 deflection of R.2 a little more tlian its own length from the 

 tip of Ri+2) without macrotrichire ; R^^^ a little shorter than 

 r-m ; r-m on Ri+5 immediately beyond its origin ; cell M^ 

 short-petiolate or sessile, in in this case being exactly at the 

 fork of J/]+3; ?« about one-third the outer deflection of M^ ; 

 basal deflection of Cmj about one-fourth its length beyond 

 the fork of M ; A/3+ C'mj a little more than one-half the outer 

 deflection of M3.
