264 HYMENOPTEKA. 



- 1. Theronia montezuma. 



Theronia montezuma, Cresson, Proc. Acad. Phil. 1873, p. 395 ( <$ ? )\ 



Hab. Mexico, Orizaba, Cordova (Sumichrast), Mirador x (Dr. Sartorius). 



Said to be a common Mexican species. 



2. Theronia Hneata. (Tab. XI. fig. 4.) 



Pimpla lineata, R Smith, Descr. of New Species of Hymen, p. 230 (1879) \ 



Hab. Guatemala, San Geronimo, Zapote, Panajachel 5000 feet ; Costa Rica, Irazu 1 

 6000 to 7000 feet (Rogers) ; Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 



Allied to the preceding species, but differing in having the antennae nearly as long as 

 the body (these in T. montezuma being described as " more than one half the length of 

 the body "), by the petiole not having " two longitudinal lines, divergent at the base 

 and confluent at the tip," and by the abdominal segments being lined with black at the 

 base. Face obscurely punctured, the vertex sometimes obscure black in the middle ; 

 tips of the mandibles black. Mesonotum sometimes punctured ; its sutures scarcely 

 indicated ; there are three black longitudinal lines on its surface, and sometimes it is 

 black along the edge of the pronotum. Scutellum covered with blackish erect hair ; 

 its basal fovea black. Metathorax shining, impunctate, its transverse keel well defined. 

 Petiole longer than the second segment, depressed along the sides above, so that the 

 central part is raised ; and in the centre of the latter is a longitudinal depression ; apex 

 of the second segment raised into a transverse border. Ovipositor about one half of 

 the length of the abdomen. Areolet oblique, the lateral nervures united above or 

 nearly so. Antennae stout, microscopically pilose ; scape yellowish beneath. 



The species varies a little in size. 



^~ 3. Theronia tolteca. 



Theronia tolteca, Cresson, Proc. Acad. Phil. 1873, p. 396 {$ $ ) \ 



Cryptus ferrugineus, P. Smith, Descr. of New Species of Hymen, p. 231 (1879) 2 . 



Hab. Mexico, Orizaba 1 (Sumichrast), Valladolid in Yucatan ( Gaumer) ; Nicaeagua, 

 Chontales (Janson) ; Costa Rica, Cache 2 (Rogers) ; Panama, Volcan de Chiriqui 2000 to 

 3000 feet (Champion). 



4. Theronia chiriqnensis. (Tab. XI. fig. 6.) 



Hab. Panama, Volcan de Chiriqui 2000 to 6000 feet (Champion). 



In coloration identical with T. tolteca (i. e. uniformly ferruginous above, the pleurae 

 and the base of the four anterior legs inclining to yellow, the flagellum and the hind 

 tarsi black), but, if anything, longer and stouter, and differing also as follows : — The 

 ovipositor is shorter, being scarcely longer than the petiole; the metanotum has,.
