1932] A New Species of Chironomus from Jamaica

A NEW SPECIES OF CHIRONOMUS FROM JAMAICA 
(CHIRONOMIDiE) 
By Bertram I. Gerry 
Department of Agriculture, Boston, Mass. 
While examining some chironomid material, collected in 
Jamaica by W. S. Brooks and donated to the Museum of 
Comparative Zoology at Harvard University, my attention 
was drawn to several specimens which appeared to be rep- 
resentatives of Chironomus varipennis Coquillett, with a 
somewhat modified wing spotting. 
Since the original description of C. varipennis is rather 
meager, and neither the male genitalia figured nor the ratio 
between fore tibia and fore metatarsus mentioned; one 
must rely, almost entirely, upon the wing characters in 
identifying this species. 
Malloch (1915) attempted to add to the original descrip- 
tion but since the specimens in his possession, apparently, 
were badly mutilated, he succeeded in contributing but a 
single salient fact, namely, that the fore tarsi were much 
elongated — the basal segment being twice as long as the 
fore tibia. 
Fortunately, I succeeded in finding in the Harvard col- 
lection additional material (collected by Professor Nathan 
Banks at Falls Church, Virginia), which coincided with 
the original description of C. varipennis from the stand- 
point of wing venation, and with Malloch’s statement that, 
in this species, the fore metatarsus is twice as long as the 
fore tibia. 
This, I believe, definitely establishes C. varipennis which 
I have redescribed in this paper. The material from Ja- 
maica, which differs from C. varipennis in respect to body 
and leg markings; wing spotting, ratio between fore tibia 
and fore metatarsus, and structural characters of the male 
genitalia, I hereby submit as a new species.
