oped, directed strongly outward and a little forward. Three 

 proclinate fi^onto-orbitals, the hind one directed more outward 

 and representing the ordinary reclinate pair, a very small one 

 between the front two and some microchaetae outside. Front- 

 alia extended into narrow divergent prongs behind, the ocellar 

 area occupying half their length. Ocellars present. jM-oclinate. 

 Parafacialia rather broad, averaging about one-third width of 

 clypeus, with row of downwardly-directed bristles along fronc 

 edge, this row paralleled on lower half by a short row behind it 

 near lower end of eye. Cheeks almost as wide as eye-length, 

 nearly as wide as vibrissal axis. Occiput broadly bulged be- 

 hind eyes. Occiput and cheeks sparsely clothed with short 

 bristles. 



Two sternopleurals, three postsuturals. Four marginal pairs 

 of scutellars, the apical pair slightly longest. No costal spine, 

 third vein bristled about half its length, other veins bare. 

 Apical cell narrow, attenuate on distal third, open, ending in 

 v.ing-tip, the foiu'th vein onlv gently sinuate, the third vein 

 curved strongly backward distally. Hind crossvein straight, 

 nearer to small crossvein than to cubitus. Tegulae smaller 

 than average. Legs short, front tarsi but little wider than 

 others. 



Abdomen of four segments, the last two segments a little 

 longer than the first two ; without macrochaetae, with only 

 bristly hairs which are a little longer and more erect on anal 

 segment. 



Chiricahuia cavicola new species. 



One female, in small cave in rock clififs of South Fork Cave 

 Creek. Chiricahua Mts., Arizona, .S500 feet, August .4, 1917 

 (Townsend). Holotype, No. 21580. U. S. N. M., TD. 5130. 



Length of body, 5 mm.: of wing, 4.5 mm. Lemon-yellow; the ab- 

 domen, mesoscutum, scutellum, tibiae and tarsi brown ; the pleurae, 

 antennae and palpi light rufous. Frontalia brownish-rufous. Ptilinal 

 suture conspicuously brown. Wing veins yellow, a small slight cloud 

 at stigma ; hind crossvein conspicuously clouded, also second, third 

 and fourth veins evenly so on apical fifth of wing. Tegulae watery- 

 white. In some lights the abdomen and scutellum appear yellov.- and 

 the mesoscutum polished black. 



This strange fly appears to belong in or near the Melano- 

 phorinae, and may be parasitic in son.ie cave-frequenting host.
