apex. Palpi ; first segment subquadrate, second with a length fully three times 

 the diameter, the third a little longer, more slender, the fourth nearly twice 

 the length of the third. Mesonotum yellowish brown, sparsely haired. Scu- 

 tellum, postscutellum and abdomen a nearly uniform fuscous yellowish, the 

 halteres somewhat lighter. Coxae and femora yellowish white, tibiae yellowish, 

 tarsi fuscous yellowish, darker apically ; claws moderately slender, unidentate, 

 the pulvilli short, with a length over twice the diameter and apically a pectinate 

 spur; dorsal plate long, triangularly emarginate, the lobes broad, obliquely 

 truncate and sparsely setose. 



Female. — Length 2 mm. Antennae extending to the second abdominal 

 segment, sparsely haired, fuscous yellowish; 14 subsessile segments, the fifth 

 with a length 2J/2 times the diameter, the circumfili extending to the basal 

 fourth ; terminal segment reduced, subconical. Palpi ; first segment with a 

 length three times its width, second a little longer, broader, the third J^'2 

 longer than the second, the fourth nearly twice the length of the third, dilated 

 apically. Face and mouth-parts fuscous yellowish. Mesonotum fuscous yel- 

 lowish. Scutellum yellowish, postscutellum fuscous yellowish. Abdomen mostly 

 light fuscous yellowish, the ovipositor apically fuscous, its lobes yellowish. 

 Halteres, coxae and femora basally yellowish transparent. Ovipositor nearly 

 as long as the body, the lobes triarticulate. The basal segment irregularly 

 quadrate, the second suboval and nearly fused with the third, which latter 

 tapers to a narrowly rounded apex. Type Cecid 02381. 



Camptomyia tsugae new species. 



This large midge was reared in March from yellowish orange 

 larvae found under the bark of hemlock, Tsnga canadensis, bored by 

 the spotted hemlock borer, MelanopJiila fiilvoguttata Harr., and for- 

 warded to this office by Herman W. Merkel, of New York. The 

 female, when at rest, carries the antennae slightly curved and nearly 

 at right angles to the support, the slender ovipositor being recurved 

 over the back. A gravid female contained about 40 eggs, each ap- 

 proximately .12 mm. long, narrowly lanceolate and so arranged within 

 the body as to give, by transmitted light, a " herring-bone " effect. 



Larva. — Length about 6 mm., yellowish orange, with a slender, distinct 

 breastbone. Head stout, the margins rather heavily chitinized, the antennae 

 biarticulate, stout, moderately long. Skin smooth, the posterior extremity bi- 

 lobed, each lobe with a dorsal, slightly recurved, chitinous process. 



Male. — Length 3.5 mm. Antennae 5^ longer than the body, thickly haired, 

 fuscous yellowish, the stems whitish transparent ; 27 segments, the fifth with 

 a stem J4 longer than the cylindric basal enlargement, which latter has a 

 length ^ greater than its diameter ; distal whorl of setae long, stout. Penulti- 

 mate segment reduced, subsessile, the terminal segment narrowly oval. Palpi : 

 first segment subrectangular, the second a little longer, stouter, the third }i
