146 HYMENOPTERA. 



which is not mentioned by Cresson) being black with a ferruginous tinge ; the costa is 

 also blackish ; the areolet as in /. phwdra ; there are no tubercles on the metanotum ; 

 the abdomen is longitudinally aciculate; the middle of the postpetiole is more dis- 

 tinctly separated from the sides; the pubescence is denser on the pleurae; and is altogether 

 a broader and stouter insect. The body is entirely ferruginous. 



21. Ichneumon phaedra. 



Ferrugineus ; facie orbitisque oculorum flavis ; flagello antennarum, linea ad basim seutelli, metanoto abdomi- 



nisque segmento 3° nigris ; alis fulvo-byalinis. 

 Long. 17 millim. 



Hab. Guatemala, Purula (Champion). 



Body covered with a close fuscous pubescence, which is longest on the thorax. Head 

 slightly, the mesonotum more strongly and closely punctured ; pleurae obscurely striated. 

 Scutellum a little broader than long, the sides carinate in front, the apex rounded 

 and prominent; postscutellum distinct, broader than long, rounded at either side, 

 smooth, shining, scarcely punctured. Metathoracic areas distinct, all clearly defined ; 

 lateral tubercles blunt. Petiole smooth, shining, impunctate, except for one or two 

 punctures along the sides, which are indistinctly keeled. Postscutellum closely 

 punctured like the thorax. Abdomen closely and strongly punctured ; the base of the 

 anterior segments longitudinally striated ; all the segments constricted at the base. 

 Wing nervures blackish ; costa and stigma obscure testaceous, the latter darker at the 

 apex ; areolet triangular above. The antennae are not much longer than the abdomen. 



22. Ichneumon sycophantus. (Tab. VII. fig. 8.) 



Ferrugineus ; facie orbitisque oculorum flavis, flagello antennarum, lineis ad basim seutelli, metathorace abdo- 



minisque segmentis l°-5 m nigris, alis fulvo-byalinis, stigmate fusco. 3 •

This species differs from I. phaedra as follows : — The middle of the postscutellum is 

 not punctured (the sides in I. phwdra being punctured), but finely striated ; the gastro- 

 cceli are larger ; the base of the petiole, and a transverse band on the second, third, 

 fourth, and fifth segments are black ; the surface of the metathorax is rougher, thereby 

 rendering the areae less clearly defined, and the lateral tubercles are, if anything, larger ; 

 the coxae are more coarsely punctured ; the lateral nervures of the areolet do not touch 

 above ; and the stigma is fuscous, not testaceous. 



28. Ichneumon subfumatus. 



Testaceus ; antennarum apice nigro, medio flavo, basi fusea ; alis fere fumatis, stigmate sordide testaceo. $ . 

 Long. 15 millim.
