ABZARIA. 201 



bluntly carinate ; postpetiole strongly punctured, more than double as wide as high. 

 Gastrocceli obsolete. Areolet 5-angled, the lateral nervures converging and nearly 

 touching above. Head not buccate. Metathoracic spiracles large, acutely oval. 



The form of the petiole, it being broader than high, places this genus in the 

 " Ichneumones platyuri " of Wesmael, but it is very distinct from any of the genera 

 of that group.

Long. 13 millim. 



Hah. Mexico, Orizaba {BilimeJc). 



Head narrower than the mesothorax, retreating behind the eyes, which are margined, 

 the margin being especially developed on the inner side ; ocelli raised ; clypeus almost 

 transverse at the apex ; labrum with a long fringe of hair ; clypeal fovea? large, deep ; 

 face punctured. The head is black behind and on the vertex, except at the eyes; the 

 rest entirely yellow, except the mandibles at the base and apex, where they are piceous- 

 black. Antennae stout, opaque, covered with a microscopic down ; the joints closely 

 joined together. Thorax smooth, shining, impunctate, sparsely covered with scattered 

 down. The yellow line on the pronotum is broadest in the middle, and does not extend 

 the entire length ; the two lines on the mesonotum are shorter and thinner; the marks 

 on the mesopleurae are large, the upper one somewhat triangular, situated immediately 

 below the tubercles under the tegulae (these being also yellow) and smaller^ than the 

 other, which is in the centre near the sternum ; the mark on the metapleura is oval and 

 shorter than the smallest on the mesopleura. The pleurae are sparsely impressed with 

 large punctures. Scutellum large, flattish. Metanotum coarsely and rugosely reticulated ; 

 the apex semiperpendicular ; the areae distinct ; petiolate area wide ; supramedian area 

 much wider than long, smooth, shining, impunctate, except at the extreme apex,, where 

 it is rugose ; tubercles blunt ; there is a yellow mark on either side at the base and a 

 larger one on either side of the apex close to the top. Abdomen covered all over with 

 large, clearly separated punctures. The legs are entirely yellow, except the knees, a 

 line above the hind femora, the hind trochanters, and a large mark at the base and a 

 smaller one at the apex on the inner side of the posterior coxae, all black. 



Subfam. CRYPTINJE. 



This extensive group is very numerously represented, especially by species of the 

 genus Mesostenus, in the Neotropical Eegion . I question if it can be separated from the 

 " Ichneumonides" by any one character ; but generally the " Cryptides" are to be known 

 from them by the ovipositor projecting to a greater or less extent, by there usually being
