 along margin of eyes. 



Prothoracic lobes elliptical, well separated, clothed with flat scales, black, 

 with violaceous and bronzy reflection ; a row of setae along margin. Mesono- 

 tum clothed with ellipticd, flat dark-brown scales with a bronzy-blue reflec- 

 tion; scales on anterior margin whitish, those below lateral angles dull gray 

 with bluish reflection, setae over roots of wings dark brown. Scutellum trilo- 

 bate, with vestiture similar to and continuous with that of mesonotum, each 

 lobe with a small tuft of black bristles. Postnotum elliptical, prominent, dark 

 brown, a group of small setae near posterior margin. Pleurae dark brown, coxce 

 luteous, clothed with elliptical, flat silvery-white scales. 



Abdomen subcylindrieal, truncate apically and with many long, dark brown 

 terminal setae; dorsal vestiture black with a slight metallic reflection; venter 

 yellowish white, colors separated at sides in a straight line. 



Wings moderate, hyaline; petiole of second marginal cell one-third as long as 

 its cell, that of second posterior cell as long as its cell ; basal cross- vein distant 

 less than its own length from anterior cross- vein; scales of veins ligulate, 

 black, with blue reflection on costa, denser and slightly broader on second to 

 fourth veins outwardly. Halteres whitish with black knobs. 



Legs moderate, slender, black with bronzy and blue reflection, the femora 

 basally whitish beneath; tibia and tarsi with a strong bronzy luster beneath;

 white on outer side. Claw formula, 0.0-0.0-0.0. 



Length: Body about 3 mm.; wing 2.8 mm. 



The specimens of the larva are in too poor condition to describe. ' 



The larvae live in the water between the leaves of epiphytic Bromeliaeeae and 

 in similar situations. Mr. Busck got them in the " leaf -comer of a parasitic 

 pineapple-plant high up on a tall tree," and again in the leaf-sheaths of a 

 young palm. He also captured several specimens that came to bite in the 

 daytime.

 Obioinal Descetption of Wteomtia telestica: 



The larva is allied to W. ochrura D. & K., described above. It was sent to us by 

 Mr. Urlch from Trinidad, bred from Bromelia water. The adults were named 

 " Dendromyia guasiluteoventralis Theob." by Mr. Coquillett. 



The following is an abstract of the table : 



1. Anal processes equally developed 3 



3. Lateral comb of the eighth segment of many teeth in a long line 4 



4. Comb of a long row of single teeth, nowhere doubled 5 



5. Tube with coarse single hairs, all pale 6 



6. Air tube 5X1; spines of comb scales longer than the base telestica 



Descbiption op Male and Laeva of Wyeomyia telestica (Female Unknown) : 



Male. — Proboscis moderate, swollen apically, vestiture black with a bronzy 

 and blue reflection; beneath with a pale-brassy luster, silvery towards base; 

 labellae smaU, rounded, with fine outstanding setae. Palpi short, flattened, 

 slender, one-seventh as long as proboscis, bronzy black. Antennae moderate, 

 joints slender, subequal, rugose, coarsely pilose, black, the joints with small
