behind, subrugulose ; 2 longitudinal carinse spring from the middle 

 of the base, and diverge to the declivity, from whence they are 

 nearly parallel to the apex, the enclosed space is cancellated ; 

 2 lateral carinse, connected with the preceding by transverse 

 branches, form a system of areation as complete as in most 

 Ichneumons : hinder angles of the metathorax obtusely prominent. 

 Wings subfumato-hyaline, ciliated ; squamulte rufous ; stigma and 

 nervures fuscous ; outer side of the 2d cubital areolet decolorous. 

 Legs rufous, including all the coxae ; tarsi somewhat obscure. 

 First abdominal segment hardly longer than its apical breadth, 

 margined, bicarinated, rugulose in the middle, more deeply striated 

 at the sides, the extreme base smooth, excavated ; posterior angles 

 depressed ; in the middle of the hind margin is a smooth tubercle, 

 with a deep triangular fovea on each side, including the suture, 

 and therefore common to segments 1 — 2 ; 2nd and following 

 segments very smooth ; 2 — 3 connate, and together much longer 

 than 1 ; 4 short ; 5 — 6 annuliform. Ventral valve not surpassing 

 the anus. Terebra as long as the body. 3' somewhat smaller ; 

 antennae longer, 40-jointed ; 1st segment narrower. ^ $ . Length, 

 2 — 2J ; wings, 4 — 4J lin. 



My specimen was taken in Leicestershire ; Bignell 

 found one in S. Devon, and several more, including the 

 S , have been collected by Capron near Guildford.

Prsecedenti proxime affinis, minor, gracilior. ? . Ater, niti- 

 dissimus, ventre maximam partem pallide piceo, pedibus cum coxis 

 rufis, coxis posticis nonnunqiiam basi fuscis ; etiam femoribus 

 4 posterioribus supra vel apice, tibiisque posticis apice cum tarsis 

 fuscescentibus. Antennae feminae 27 — 33-articulatae. Metathorax 

 ut in praecedente, sed Isevior, cariuis mediis propius distantibus, 

 area inclusa angustiore, profundius cancellata. Alte praecedentis. 

 Abdominis segmentum Imum apicis latitudine nonnihil longius, 

 utrinque marginatum, bicai'inatum, ubique concinne striatum, 

 tuberculis prominulis ; caetera laevia, nitidissima. Terebi-a corpore 

 paulo longior. ^. Antennae 38- articulatae ; tibis posticae praeter 

 basin fuscescentes. 



More slender, and smaller than the last species, with longer 

 hind legs and terebra. 5 . Deep black, very shining, belly almost 

 entirely pale piceous ; legs rufous, together with the coxae ; hind 

 coxae sometimes fuscous at the base ; 4 posterior femora more or 

 less fuscescent above or at the apex ; hind tibiae at the apex, and 

 tarsi, fuscescent. Antennae J 27 — 33-jointed. Wings and meta-
