notuni riitluT ilarkor ycllowisli. I'U-iiriv. lifc'lit yellow ish, a dark spot under the l)iisc 

 of the hidloros, above the himl coxa; a clearer-deBned, though smaller, spot on 

 tlie propleiini- in the vicinity of the anterior spiracle; sternum light orunge-yeilow. 

 Ualtcros, stem short, knob large; pale yellow. Legs, pale yellow; only the two 

 terminal tarsal scgmenls slightly darker. Fore legs very widely .separated from the 

 middle legs as in the Anlochiiii. Wings: light yellowish; veins brown, (hose in the 

 costal region rather brighter-colored, stigma very indistinct. Venation: (See (ig. 

 c): Se short ending before the fork of Hs; what seems to be a branch of R;+i arises 

 from U:+j; I regard it as cross-vein r, although it is not complete and is very oblique 

 in position (such as in I'aratropcza). If this is regarded as a vein, III, then the radial 

 cross-vein is absent and the genus would run down into tlie Eriojilenni; I know 

 of no genus, at present, that can receive it. 



Abdomen: light yellow: on the sides of the 6th segment rather dark brown, and 

 here with a conspicuous widened cnlargment (possibly not normal). Ilypopy- 

 gium: (See fig. k, ka), 8th tergite short, narrower than either the 7lh or 9lli; 9t!i (a) 

 tcrgile convex on the caudal margin, with a deep median notch. Pleural pieces 

 (b) rather narrow, cylindrical, with the appendages at the end or on the ventral 

 face; the outer angle of the pleura produced into a blunt knob (c); apical append- 

 ages two, the dorsal one (<1), fleshy, inserted near the apex of the sclerite; the ventral 

 one (e) arising from the ventral side, far down near the base of the pleura; the base 

 strongly swollen, the tip chitinized bearing on the inner face, a strong tooth, swollen 

 at the base and projecting inward; the tip, slender, bent inward. What seems to 

 be the guard of the penis (f) is elongated, slender, not swollen, but pseudo-seg- 

 mented near the tip. 



Ilolotype: cf , Igarape-assu, I'ara, Brazil. Jan. 30, 191i. (II. S. I'arisli, cull.)

Tlie reference of this curioii.s .sj)cde.s to Tciicliolahis i.s provis- 

 ional, only. It seems to nic as though it niiglit he coiisidered'one 

 of the primitive forms of the genus. I take pleasure in naming 

 this in.sect after its discoverer, 'Sir. H. S. Parish, the well-known 

 collector and traveller.

The folhnving si>ecies is the second American form to be made 

 known. The two species may be separated by the following key. 



1. Thoracic pleura; without silvery band; legs pale yellow; tip of femora, base and 

 tip of tibia black; wings hyaline, extreme base dark yellow. (Southwest. 



U.S.) arizonensis Coquillett' 



Thoracic plcurje with a broad silvery-blue band; legs dark blown, uniform, wings 

 suffused with darker. (Guatemala, Cent. Am.) argeulcopleura, sp. n.
