76 INSECUTOR INSCITLt MENSTRUUS 



kind of an ocellate spot in my form again points to a relationship with ocel- 

 latus, which is also supported by the examination of the male genitalia. 



Thus we might expect our Culex chalcocorystes to have a larva simi- 

 lar to ocellatus, and as the larva under discussion fits these conditions I 

 am convinced that we are dealing with the larva of this species. 



TTius it appears that there is a small group of closely related species 

 of Culex, united by characters of the larvae as well as of the male geni- 

 talia and other peculiarities of the adults, a group in which we find every 

 degree of shortening of the male palpi. . If more support were needed 

 for the view of Dyar and Knab that the length of the palpi is entirely 

 insignificant systematically, this group would furnish it. Or shall we take 

 Culex ocellatus to be a culicine and latisquama an aedine mosquito, 

 because the palpi of the former are three-fourths, the latter only half the 

 length of the proboscis ? Or would one establish a new subfamily for 

 these two species ? 



Before closing I desire to express my sincere thanks to all my Ameri- 

 can friends, especially to Dr. L. O. Howard and Mr. Frederick Knab, 

 who helped me to obtain, during my rather brief stay, not only a knowl- 

 edge of the methods of the Bureau of Entomology and the wonderful 

 progress in sanitation in Cuba and Panama, but also introduced me into 

 the systematic study of the Culicidae, so that I am enabled to give the 

 above descriptions of new species. 



SOME BROMELIADICOLOUS BLATTID.^ FROM 

 MEXICO AND CENTRAL AMERICA 



By A. N. CAUDELL 



Tlie following species of Blattidae were taken in epiphytic BromeHa- 

 ceae in Cordoba, Mexico, 1908, by F. Knab, and in Panama by 

 A. H. Jennings. But two of the nine determined species here listed 

 are included by Seiior C. Picado in his recent comprehensive treatise 

 on the fauna of these plants. To the few species of Tettigonidae 

 recorded by Picado should be added the wingless Copiphoriine, Decti- 

 nomima jenningsi Caud., described in 1910 from specimens taken in 

 Bromelias by Mr. Jennings. 



The number of species of insects to be found in Bromeliads is prob- 

 ably greater than published records would indicate. Especially is this
