MOSQUITO FAUNA OF PANAMA BUSCK JJ 



but these hatched nevertheless successfully, together with the non- 

 submerged eggs, during the afternoon of the same day. The young 

 larvse were white, with black mouth-parts and black lateral hairs 

 pointing forward on the anterior half of the body. They remained 

 under water for several hours, eating of the vegetable matter at the 

 bottom of the jar to which they had been transferred. The next 

 morning the larvse had doubled in size, and on the third day they 

 attained their full size ; they came regularly, though not very fre- 

 quently, to the surface to breathe. When feeding on the bottom 

 they would lie in the soft residue of vegetable matter in different 

 positions, sometimes on their back, sometimes with the back up, or 

 on the side. The first adult from this lot issued May 14. 



The adults of this and other species of Johlotia are conspicuous 

 objects in the bamboo woods, when they approach to bite, gracefully 

 floating their long white-tipped middle and hind legs. 



JOBLOTIA MOGILASIA Dyar and Knab 



Bred with the two preceding species from bamboo near Tabernilla. 

 While the larva and adult in a general way look much like the two 

 other species, the pupa of this species is easily distinguished from 

 the somber, dark pupa of the others ; it is bright yellow, prettily 

 marked with black cross-bands on the back of the abdominal seg- 

 ments.
