Genus Dendromyia. 313 
such a marked difference, and having been received from a fresh 
locality, I took them for a distinct species. Dr. Lutz now sends 
me two ¢’s of the longirostris, and this enables me to see that 
the two species are the same. The name T'rinidadensis must, 
therefore, sink as a synonym. A photograph of the wing of 
the ? is given on page 312. 

Genus 42. DENDROMYIA. nov. gen. 
(Plate XV.) 
Allied to Wyeomyia, but differs in that the scutellum has 
smaller flat scales much rounded apically, and the wings have 
long, broad, dense Taeniorhynchus-like scales, some ending 
asymmetrically. The head is covered with flat scales; basal 
joints of antennae scaly. Mesothorax with large spindle-shaped 
scales ; prothoracic lobes with flat ones ; fork-cells long. Proboscis 
of moderate length, swollen apically. It differs from Phoniomyia 
in the much shorter proboscis and more densely scaled wings 
(vide Plate XV.). Five species are known. 
DENDROMYIA ULOCOMA. n. sp. 
Head covered with flat dark brown scales. Thorax shiny 
ochraceous brown, with spindle-shaped bronzy-brown scales ; 
prothoracic lobes with the same. Abdomen ochraceous-brown, 
covered with dusky-black scales, unbanded and unspotted ; venter 
pale ochraceous. Legs and proboscis brown, unbanded. 
9. Head dark brown, covered with flat dark scales, a few 
paler ones round the eyes, two black bristles projecting between 
the eyes, and a few dark shorter ones over them ; antennae, palpi, 
proboscis, and clypeus dark brown, the antennae with the basal 
- and second joints with small dark scales. 
Thorax bright shiny ochraceous brown, covered with rather 
large spindle-shaped dusky scales ; prothoracic lobes with similar 
coloured flat scales; scutellum paler ochraceous, with similar 
scales to the mesothorax ; metanotum deeper brown, with brown 
chaetae; pleurae bright ochraceous, with numerous flat white 
scales.
