SPONGILLA-FLIES — PARFIN AND GURNEY 507 



H. S. Parish collected in December 1912 in Bartica, which is 40 

 miles up the Equessibo River, as evident from the account of his 

 itinerary and the records of his crane-fly collections, quoted by 

 Alexander. (Trans. Amer. Ent. Soc, vol. 40, pp. 223-255, 1914.) 



This is one of two species of Climacia, the other being himaculata 

 Banks, with the same type locality data. The two are readily 

 distinguishable by the occm-rence of an elongate radiomedial streak 

 in basalis in contrast to a tranverse one in himaculata. 



C. basalis closely resembles nota from Venezuela, from which it is 

 separated on the basis of the longer, more crescent-shaped radio- 

 medial streak, the anal streaking and the more elongate latero- 

 ventral halves of the ninth tergite in basalis. The forewing of basalis 

 is also similar to that of chapini, from the United States, but differs 

 in the shorter and slightly broader basal radiomedial streak (which 

 extends from about Rs+MA to slightly beyond 1st r in basalis, 

 but from the junction of R and MP in chapini), the small or absent 

 antepterostigmal spot, the longer and narrower lateroventral halves 

 of the ninth tergite of the female in basalis.

Female (holotype): Head with vertex shining, blackish brown, 

 with color extending to a small point between antennal sockets; 

 face yellowish brown; palpi yellowish; basal two antennal segments 

 pale yellowish; legs pale yellowish; pronotum brownish yellow, with 

 irregular brownish streaking and faint median dorsal streak, meso- 

 notum and metanotum yellow dorsally, pleura yellowish; abdomen 

 yellowish brown. 



FoREWiNC (pi. 2, fig. 6): Length approximately 3.9 mm., width 

 about 1.4 mm.; membrane yellowish with two distinctive large 

 transverse dark brown spots, the first larger, the basal radiomedial 

 streak running transversely across wing, beginning at about Rl 

 where it is broadest, and extending posteriorly to Cu2, where it is 

 considerably narrower, the second (the antepterostigmal) spot, of 

 the same general shape as the radiomedial streak, but beginning at 

 costal margin, where it is broadest, and narrowing considerably below 

 Rl to just before Rs; pterostigma yellowish behind antepterostigmal 

 spot; venation yellowish except for brownish outer gradates and 1st 

 and 2d r; Rs forking into R2 + 3 and R4 + 5 basad of point of coales- 

 cence of Sc and Rl ; MPl + 2 with first fork at a slight angle; Cul with 

 three branches to margin in right wing, four in left; 1st r in radio- 

 medial streak, 2d r just before point of coalescence of Sc and Rl,
