A Bromeliad-Inhabiting Crane-fly (Tipulidae, Dipt.) 



By CHAS. P. ALEXANDER, Ithaca, N. Y.* 

 To the rather long list of inhabitants of the Neotropical epi- 

 phytic, water-bearing Bromeliaceous plants, (as given by Dr. 

 Calvert in ENTOMOLOGICAL NEWS, Nov., 1911, pp. 402-411), 

 there should be added the family Tipulidae. I have recently re- 

 ceived specimens of a Costa Rican Mongoma that were bred 

 from Bromeliads by Sr. C. Picado. I am indebted to Mr. Fred- 

 erick Knab, of the U. S. National Museum, for the privilege 

 of examining these specimens.
