This species bears a striking resemblance to Spilogader fulva 

 Bigot, a species recorded under another gcneiic name on a sub- 

 sequent page of this paper and which occurred along with the 

 tj^pe seiies. 



I know of no closely allied North American species, the gloss}^ 

 fulvous thorax and abdomen readily separating it from any species 

 known to me. 



Phaonia fuscicauda sp. n. 



Male. — Yellowish testaceous, slightly sliiiiiug. Head yellow, occiput with 

 more than the upper half gray, pruinescent; third anteiinal joint Ijrown except 

 at base. Dorsum of thorax slightly gray pruinescent and with four indistinct, 

 brown vittae, the submedian pair with dark sutTusioii between them so that 

 they appear almost like a broad median vitta. Abdomen with a medio- 

 dorsal row of fuscous spots, the one on third segment most distinct, apex of 

 third segment and whole of fourth fuscous, the large bristles on the last two 

 segments with the base of each surrounded b}^ a fuscous dot. Legs yellowish 

 testaceous, tarsi slightly darkened. Wings clear, cross-veins conspicuously, 

 but not very broadly, infuscated. Calyptra whitish. Halteres yellow. 



Eyes conspicuously hairy, separated at narrowest part of frons by a dis- 

 tance equal to width of anterior ocellus; antennae reaching almost to mouth 

 margin, third joint narrow, slightly dilated at apex, over two and one-half times 

 as long as second; arista plumose, the longest hairs equal in length to width of 

 third antennal joint; parafacials in {)rofile narrower than third antonnal joint; 

 cheek slightly less than one-fourth as high as eye, marginal bristles irregular, 

 moderately strong, none upwardly curved, a double series of hairs above 

 bristles; proboscis very stout. Thorax with two to three pairs of widely 

 placed presutural acrostichals and about eight series of hairs on same area; 

 postsutural dorso-centrals foin-; sterno-i)leurals three; hj-popleura bare; poste- 

 rior spiracle large, subtriangular. Abdomen broadly ovate; fifth sternite with 

 a broad wedge-shaped excision. Fore tibia unarmed at middle; mid femur 

 with nine to ten long hair-like bristles from base to beyond middle on postero- 

 dorsal surface; mid tibia with two to three posterior bristles; hind femur with 

 a complete series of rather short bristles on antero-ventral surface and another 

 on basal half of postero-ventral; hind tiljia with one to three antero-ventral, 

 and two antero-dorsal bristles, calcar not very long; outer cross-vein at about 

 its own length from inner; last section of veins 3 and 4 slightly di\ergent at 

 apices, that of the latter about three times as long as preceding section.
