Might be an iGhneimon, but for its exserted ovipositor. Allied to 

 Pliygadeuon desertor, Gr., from which it differs in the number of white 

 joints of the antennae, the coloration of the legs, the sculpture of the 

 metathorax, etc. 



One specimen from the London district. 



The following strange piece of synonomy among the IchneimonidcB 

 deserves mention, if only for the purpose of inviting criticism. Of its 

 truth I have thoroughly convinced myself, although unwillingly. 



$ Ichneumon crassipes, Gr., i, 622. 

 ^ Ichn. latrator, Gr., i, 572 {excl. ? ). 



$ Var. with short wings, Brachyj)terus means ^ Gr., i, 675 ; 

 Ste. Mand. vii, pi. 40, fig. 2 ; Pterocormus means, Forst., 

 Mon. Pez., 24. 



The original description of JBrachypterus means was drawn up by 

 Gravenhorst from a single specimen sent him by the Eev. F. W. Hope 

 from Netley, in Shropshire. A similar form does not seem to have 

 occurred on the Continent ; but I fortunately possess four, taken long 

 ago somewhere in the Midland Counties, — I believe at Bridgenorth. 

 They agree ad amussim with I. crassipes, even in the sculpture of the 

 metathorax, the most certain proof of identity. My specimens of /. 

 crassipes are undoubtedly rightly named, havin^ passed through several 

 examinations, including one by the late Mr. Desvignes. 



Genus Aptesis, Forst., Mon. Pezom., 34. 



The insect named Fezomachus hemifterus by Gravenhorst (ii, 874) 

 was described from a single German specimen, now lost. Upon the 

 strength of that description only, it is placed in Forster's genus Aptesis ; 

 he rightly remarking that it cannot be assigned to any other. It cannot 

 be assigned even to Aptesis, unless the following character of the genus 

 be modified, " das erste Segment punktirt, nicht langsrunzlig," for the 

 first segment of A. hemiptera is most distinctly wrinkled longitudinally. 

 One of the new species here to be described exhibits the same rugosity, 

 and it is only by claiming for them the same pri\ilege as for hemiptera 

 that I can allow myself to refer them to this genus. 



Aptesis geaviceps, n. sp. 

 A. nigra, capite maximo, antennis piceis, hasi testaceis, alho semi- 

 annulatis ; ahdomine picescente, segmentis V apice, 2^" disco, plus minus
