extensive study of the mosquitoes breeding in this region, 
since in my opinion such observations would very probably 
be repaid by finding many interesting species. 
Anopheles albimanus Wiedemann. From one to four 
adults of this species were collected each morning on the in- 
side of the wall netting and cloth ceiling of the camp. They 
probably gained entry through numerous small holes and 
rips in the netting. Cursory examinations of several of 
the nearby pools and streams were made but no larvae of 
this or other species of Anopheles were found. 
Anopheles punctimacula Dyar and Knab. Two females of 
this species were captured on the ceiling inside the camp. 
Culex bonne\x Dyar and Knab. Adults of this species 
were bred from the larvae present in considerable numbers 
in a ground pool (in which the end of a tree trunk was ly- 
ing). The finding of this species in Panama increases our 
knowledge of its distribution since it previously has been 
reported only from Dutch Guiana where it is a common 
species and breeds in artificial receptacles, tree holes and 
ground pools. 
Culex corniger Theobald. Larvae of this species were 
numerous in several small ground pools. 
Culex coronator Dyar and Knab. Numerous larvae were 
present in a ground pool surrounding the base of a large 
stump in the cleared area. 
Culex declarator Dyar and Knab. This species was breed- 
ing in profusion in water in a natural hollow in a log in the 
clearing. 
Culex inflictus Theobald. Breeding in old tin cans where 
it occurred both alone and in association with Joblotia dig- 
itata. The larvae were also found in a hollow in a log in 
company with Hsemagogus lucifer. 
Aedes angustivittatus Dyar and Knab. Represented by 
three females that were captured while biting man at the 
edge of the forest. 
Aedes quadrivittatus (Coquillett) . Several females were 
captured near the camp while in the act of biting man. They
