SOME BROMEUADICOLOUS BLATTIDyt 77 



probable if transient visitors are included, such as some of the recorded 

 species very surely are. Many of the recorded forms are, on the other 

 hand, truly bromeliadicolous. As typical examples of true bromeliadi- 

 colous insects may be mentioned the dragon fly, Mecistogaster modestus, 

 the brachypterous roach, Homalopteryx scotti, and various species of 

 Diptera, especially mosquitoes. 



Of the Blattidae herein treated one species at least, Audreia hromeli- 

 arum, n. sp., is perfectly at home in the Bromelias. The collector, Mr. 

 Jennings, found these roaches would dive boldly into the water when 

 disturbed. Most roaches found inhabiting these plants are apterous, 

 brachypterous, or of a compact structure, forms apparently well adapted 

 to an aquatic or subaquatic existence. One of the species herein de- 

 scribed, however, Latindia armata, n. sp., has large elytra, seemingly but 

 poorly fitted for such surroundings. 



Aside from the systematic interest of containing three species sup- 

 posedly new to science, the present lot of roaches is remarkable for the 

 small proportion of the species before recorded as bromeliadicolous. 



Ischnoptera occidentalis Saussure. 



One female, Cordoba, Mexico, April 28, 1 908, F. Knab. 



Blattella nahua Saussure and Zehntner. 



Three males, three females, Cordoba, Mexico, March 19 to April 28, 

 1908. F. Knab. 



Blattella sp. 



Four males, Cordoba, Mexico, April 5, 1908, F. Knab. 



Nyctibora brunnea Thunberg. 



One female (nymph), Porto Bello, Panama, A. H. Jennings. 

 Audreia marginata, new species. * 



One female, Porto Bello, Panama, A. H. Jennings. 



Apparently most nearly related to Audreia carinulata Saussure but is 

 structurally quite different, especially the armature of the legs. The mid- 

 dle and hind metatarsi of A. carinulata are distinctly spined beneath, 

 while in marginata they are unarmed, at least those of the middle legs, 

 those of the hind legs being missing from the unique tj^e specimen. 



Size medium, form moderately convex. Head slightly exposed. Pro- 

 notum a little broader than long, anteriorly elliptical, posterior roundly
