48 A REVISION OF THE NEARCTIC SCIOMYZIDAE 



band. Although described from Mexico, I have seen a male from 

 Texas in the U. S. National Museum collection (det. Coquillett), 

 which seems to be correctly determined. It is probable that 

 Loew's species is synonymous. It was described from a male 

 from Texas. 



c?, 9 • Similar to nana. Wings hyaline with fuscous stigma and marginal 

 cell and fuscous transverse bars as follows: four in submarginal cell beyond 

 frst vein, one in first posterior c: '11 each side of small cross-vein, and one beyond; 

 two in discal cell, and one along fourth vein in second posterior. Cross-veins 

 also clouded, and there are other faint indications of bars basad of the small 

 cross-vein. Abdominal segments with broad brown bands which are inter- 

 rupted laterally by a continuous narrow gray stripe; the ventral lobes of 

 such segments narrowly gray. 



Melina (Graphomyzina) guttata Coquillett 



1901. Sciomyza guttata Coquillett, Proc. U. S. Nat. Mus., xxiii, 615. 



The wings in this species are intensely Ijrown, with numerous,, 

 small, quadrate, evenly arranged diluted spots, suggesting Tetan- 

 ocera ambigua Loew. 



9 . Similar to maculata but orbital spot at antennae velvety black ; occiput 

 with a horizontal brown post-orbital stripe; mesonotum finely irrorated 

 with brown, not vittate; humeri and notopleura immaculate. A distinct 

 black or brown stripe beneath humeri to root of wings and another, velvety 

 brown spot between wings and halteres. Scutellum with large brown discal 

 area. Halteres with dark spot on knobs. Abdomen gray with brown irro- 

 rations, becoming dense and coalescing at bases of segments, and also form- 

 ing a more or less complete, broad median stripe. Legs with brown apices 

 to middle and hind femora, and tibiae; two basal joints of middle and hind 

 tarsi white; two apical ones black. Wings intensely fuscous with numerous 

 small quadrate diluted spots arranged in two series between the veins, but 

 only in two isolated groups of two or three in submarginal cell. Costal 

 margin and apex broadly fuscous. 



Originally described from a female from Texas. Type in the 

 United States National Museum (no. 5502), from which the 

 above description is drawn. 



Melina (Graphomyzina) maculata new species (PL I, fig. 14.) 



This species seems to be similar to the European Melina 

 (Di taenia) schoenherri Fallen. The series shows some variation 

 in the color of the fore legs, which may be entirely black or at 

 most knees and tarsi pale. 



cf. Brown to tawny; frons anteriorly, antennae basally, face, checks, 

 palpi, halteres, fore coxae, middle and hind tibiae and tarsi, pale. Wings
