ANOPHELES TARSIMACULATA Goeldi 



Two specimens were attracted to my tent at Tabernilla by the light. 

 These specimens appear to have flown at least three hundred yards 

 from the nearest possible breeding place, which was in the swamp 

 back of the residence hill at Tabernilla. Their flight, however, was 

 aided by the shelter of intervening trees and houses. 



ANOPHELES EISENI Coquillett 



This large white-kneed Anoplicles was bred from larvae taken in 

 water in hollow trees and in bamboo-joints near Tabernilla. It was 

 also bred from a palm leaf, lying on the ground and filled with rain- 

 water, on the banks of the upper Chagres River. Other Anopheles 

 larvae, taken in water in the leaf corners of Spanish bayonet near 

 Tabernilla, were not bred, but possibly belonged to this species.^ 

 The supposed Anopheles larvae, reported to have been found in the 

 leaf-corners of the banana, are probably all larvae of small flies be- 

 longing to the genus Corethrella. The small, triangular, often red- 

 dish, larvae have a certain resemblance to those of Anopheles and 

 were sent me from sanitary inspectors as such on two occasions. 

 They are very abundant on the Zone and are sometimes found in 

 bananas as well as in tree-holes and bamboo- joints, feeding in part at 

 least on young mosquito larvae. 



The possibility of Anopheles breeding between the leaf-stalks of 

 the banana might at times be of importance in the practical work 

 against mosquitoes and has at least in one instance caused extra work 

 and expense for the Sanitary Department on the Zone ; but I have 

 personally never found Anopheles larvae in these plants, though I 

 made it a point to investigate them, whenever an opportunity pre- 

 sented itself. 



It would be of advantage in the practical mosquito work on the 

 Canal Zone to ascertain whether this tree-hole-inhabiting Anopheles 

 is capable of transmitting malaria. Its circumscribed breeding places 

 necessarily limit its abundance, and the species can therefore at most 

 not be a very important factor in the spread of the disease. The 



^Anopheles bellator D. & K. was bred from the leaf corners of Spanish 

 bayonet in Trinidad, and this species may have to be added to the list. The 

 present larvae were not bred ; no adults of bellator were captured. As this is 

 going to press, Mr. Jennings has sent in an example of Anoplicles lutzii Theob. 

 (not Cruz), which he bred from larvae in the water in Tillandsia leaves. If 

 this should prove to be a malaria-carrying Anoplicles. the removal of epiphytic 

 plants from trees in the vicinity of habitations would lie imperative.
