1932 ] A New Species of Chironomus from Jamaica 71 
brown, banded with yellow; coxae blackish; femora brown 
with subapical yellow ring; tibiae predominately yellow, a 
narrow brown subbasal ring and a second narrow brown 
ring half way between mid-point and apex; tarsi brown 
with yellow bands, basal segment brown with wide central 
yellow band, remaining segments brown with yellow apical 
ring, these rings often extending beyond joint and involving 
base of following segment. Fore metatarsi, less than one 
and one-half times length of fore tibiae (18-14). Wings 
with nine black spots ; the five large spots at middle form- 
ing two false fasciae, two of the remaining spots at apex 
(one on either side of media) , the other two at base. Distal 
fascia, located half way between cross-vein and apex; con- 
sisting of large squarish spot below apical portion of vein 
(Cui), the second spot directly above in cell (R 4+5 ), the 
fascia completed centrally by distal portion of large rectan- 
gular spot in cell (Mi). Proximal fascia, immediately be- 
yond cross-vein, consisting of squarish spot involving junc- 
tion of veins (Cui) and (Cu 2 ) and extending to posterior 
margin of wing, the second spot directly above in basal 
portion of cell (R 4+5 ), completed centrally by proximal por- 
tion of large rectangular spot in cell (M 4 ). The basal spot 
in anal area usually circular, the other triangular in outline. 
Hypopygium with side piece terminating in sickle-shaped 
appendage, densely clothed with numerous long hairs. A 
long dorsal spine, ventrally curved. 
Female. — Similar to the male in coloration.

Faded specimens may sometimes resemble C. varipennis 
but the two species are easily separated on the basis of 
structural characters found in the male gentalia.
