(5 ) Female palpi less than half the length of the 
proboscis. Male palpi considerably shorter than the 
proboscis. Bristles on the mesonotum unusually 
long. Genus io. — Dasymyia 
( b .) Head with a few narrow-curved scales either on 
the vertex or the nape or forming a central line, and 
broad spatulate scales over the rest of its surface. 
Scutellum with spatulate or with narrow-curved and 
spatulate scales. 
(i.) Head with smoothly-laid flat scales except 
on the nape when there are a few narrow-curved. • 
Mid lobe of scutellum with small flat scales lateral 
lobes with narrow-curved ones. Genus n.—P hagomyia. 
(2.) Head with spatulate scales and a few narrow- 
curved on the nape. Scutellum with spatulate scales 
on the mid lobe and narrow-curved ones on the 
lateral lobes. Genus 12.—Catageiomyia 
(3.) Head with flat scales except on the nape 
where there are some narrow-curved ones. Scutellum 
with fusiform scales on the mid lobe and flat ones 
on the lateral lobes. Genus 13.—Polyleptiomyia. 
(4.) Head with spatulate scales and a few narrow- 
curved ones on the vertex. Scutellum with spatulate 
scales only. Genus 14.—Scutomyia. 
(5.) Head with scattered narrow-curved scales on 
the nape a central line of similar scales and spatulate 
scales over the rest of its surface. Scutellum with 
the central lobe clad with fusiform scales in the 
middle line and small scales on either side of this and 
lanceolate scales on the lateral lobes. Genus 15.—Hulecoeteomyia. 
(6.) Head with a median line of narrow curved 
scales and spatulate scales over the rest of its surface. 
Scutellum with spatulate scales on the median lobe 
and narrow-curved ones on the lateral lobes... .Genus 16.—Macleaya. 
( c .) Head with spatulate scales only or with spatulate 
scales and a few narrow-curved ones confined to the 
middle line. Scutellum with narrow-curved scales only. 
* Note.— The term normal used in connection with cross-veins of wing means such a condition as i 
found in the cross-veins of a culex which in the vast number of mosquitoes is the usual position. The mi 
cross vein is in line with the median and the commencement of the posterior cross-vein is always on th 
side of the median nearer the base of the wing.
