MOSQUITO FAUNA OF PANAMA BUSCK 73 



This species looks very much like and has identically the habits 

 of Wyeomyia psciidopccteii D. & K., bred from similar flowers in 

 Trinidad and Santo Domingo. As in this species, the eggs, which 

 are black, smooth, and elliptical, are laid singly, but in large 

 numbers, in the uppermost, just-opening, and yet dry flower 

 sheath, where they await a rain for their development. 



WYEOMYIA LEUCOPISTHEPUS Dyar and Knab 



Bred from Tillandsia on branches of a tree near Tabernilla. 



WYEOMYIA CODIOCAMPA Dyar and Knab 



Adults of this species were repeatedly taken in the bamboo woods 

 near Tabernilla, where they came to bite. Only two larvae were 

 taken, both in the bamboo traps. These were the most extraordinary- 

 looking mosquito larva;, which have come under my observation, 

 and resemble more young caterpillars than dipterous larvae ; they are 

 short, fat and rotund, and covered with many long black spines in 

 closely set clusters. The movement of the body is therefore short 

 and slow, and they remain for long periods under water, quietly 

 feeding in the decomposed vegetable matter on the bottom. 



WYEOMYIA MACROTUS Dyar and Knab 



The larvae of this species were found, together with those of 

 PJionioniyia scotinoinus, in Tillandsia on trees along Bogueron 

 River. Only a few specimens survived the upsetting accident on 

 my way home. They have a very long, thin tube and lie on their 

 backs, with the tube downward for long periods at a time. The 

 species was also bred from bromelia water near Tabernilla. The 

 pupae of this species have very remarkable long, thread-like breath- 

 ing tubes, quite dififerent from the short, stout tubes normally found 

 in mosquito pupae. The length of these tubes keeps the pupa well 

 under the surface of the water w^hen it takes air, and this may likely 

 be of value to the species in the limited and often crowded surface 

 area of its habitat. 



WYEOMYIA HOSAUTUS Dyar and Knab 

 Bred from bamboo near Tabernilla. 



WYEOMYIA MELANOCEPHALA Dyar and Knab 



Bred from a single larva taken, together with Cnlcx and Ano- 

 pheles larvae, in a nearly quiet pool of a slow-running, cold, clear 

 brook in the mountains back of Empire.
