recurrent and the second transverse cubital nervures ; the 

 latter is received shortly beyond the middle of the areolet. 

 Abdomen smooth, shining, impunctate ; the fifth and 

 sixth segments broadly black ; the gastrocceli shallow, not 

 very distinct, finely aciculated. The ventral segments 

 are pallid-yellow in the middle. 



Ichneumon brouni, sp. nov. 



Long. 7 mm. c^. 



A very similar species to I.falsus, but is smaller ; the 

 sternum is black ; the hinder coxae are without any 

 black ; the petiole is smooth, not shagreened ; the gastrocceli 

 are deeper and more clearly defined ; and the recurrent 

 nervure is broadly curved, while in /. falsus it is slightly 

 angled in the middle and emits there a short branch. 



Antennae black, the scape yellow beneath ; the apical 

 joints of the flagellum dilated on lower side. Head pale- 

 yellow ; the occiput, and the vertex and front broadly in 

 the centre, black ; the tips of the mandibles black ; 

 the face sparsely pilose ; the clypeus with longish pale, 

 the vertex thickly covered with black hair ; shagreened ; 

 the hollowed front smooth and shining. Thorax black ; 

 a broad line of equal width on the pronotum, two 

 lines on the mesonotum, scutellum, post-scutellum, the 

 median segment, the lower edge of the pronotum, 

 a short line opposite the tegulse, the scutellar keels at the 

 base, the scutellum, post-scutellum, two large marks on 

 the apex of the median segment, the tubercles, the lower 

 half of the mesopleurae, and a line on the lower side of 

 the propleurse, lemon-yellow. The mesonotum has the 

 punctures somewhat close together, those on the scutellum 

 are larger and more widely separated ; the median seg- 

 ment has only a few minute punctures at the base. The 

 propleurse have the punctures shallow and widely
