194 ENTOMOLOGICAL NEWS [May. 'll 



Larval Case: Length 21-27 mm., and of almost uniform diameter; 

 thatched outside with short flat pieces of dried grass, closely applied, 

 and overlapped or shingled longitudinally. 



Described from four males bred (May, 1910) from larvae 

 and numerous cases collected at Biloxi, Mississippi. Types are 

 deposited in the U. S. National Museum and in my own col- 

 lection. 



The female is wingless and grub-like as in the related spe- 

 cies ; a single female was bred but was not secured in condi- 

 tion for detailed description. Like confederata, this insect 

 passes the winter as a larva, apparently always in the last lar- 

 val stage, and feeds for a short time in early spring, suspend- 

 ing its case to some tree, fence, or twig for final transforma- 

 tion. Though apparently by choice a grass-feeder in swampy 

 places, the spring-time food is often the petals of flowers, and 

 several larvae were found devouring the tender yellow petals 

 of pitcher plants {Sarracenia sledgei). Though of less ex- 

 panse, this is a much more robust insect than the well-known 

 E. confederata G. & R. and its larval case is proportionately 

 larger. I take pleasure in dedicating this interesting species to 

 Prof. S. M. Tracy, whose hospitality and knowledge of the 

 district and its flora added greatly to the pleasure and profit of 

 my stay at Biloxi. 



Cases of Phoresie.

The cases where insects are transported by other insects 

 are comparatively few. Among the mites, there are long 

 series of forms in which it is the rule that the mite is in some 

 of its stages transported by insects. The well-known case of 

 the triungulins of Meloidae, being carried by bees, is found in 

 all text-books. But there is a considerable number of records 

 of other insects being transported by larger insects. Some 

 years ago Mrs. Slosson sent me some Chrysopids from Mt. 

 Washington that had, clinging to their wings, some small flies.
