37ti Mr. Bridgman's additions to T. A. Marshall's 



metathorax without area?. First three segments of abdomen 

 punctate, interstices reticulate ; apex of 3rd free from punctures ; 

 base of 4th punctate, the remainder reticulate ; 1st segment a little 

 longer than wide, sides almost parallel ; 2nd transverse. Legs 

 moderate. Wings without an areolet ; transverse anal nervure 

 divided a little below the middle. 



Black ; a yellow mark in middle of the face, an oblong mark in 

 front of wings, a streak below, sides and extreme apex of scutellum 

 yellow. Legs red ; coxte, base of trochanters, apex of hind tibiae 

 and hind tarsi black ; apical joint of front and middle tarsi 

 fuscous. Tegulae and base of wings yellow ; stigma fuscous, 

 extreme base slightly paler, Female. Length, 7"5 mm. 



One female taken by Mr. G. C. Champion at Avie- 

 more. This Bassus appears to be undescribed ; the 

 colour of the scutellum and coxa?, as well as the sculp- 

 ture of the base of the abdomen, is distinct from any I 

 can find described. 



Ephialtes ruficollis, Desvig. 

 Desvig., Mus. Cat. Brit. Ichn., 88, 11. 



The Bev. T. A. Marshall has placed this insect in his 

 catalogue as a sj'nonym of Thalessa clavata, ¥., but this 

 is a mistake ; it is a true Ephialtes. I have a male and 

 female bred by Mr. C. G. Barrett many years ago. The 

 transverse ordinary nervure is interstitial, and the trans- 

 verse anal almost opposite and divided in the middle ; 

 the male has a narrow testaceous band at the base of 

 the 2nd and 3rd segments. 



If Thalessa clavata is included in the catalogue on the 

 strength of Desvignes' insect, then it must be removed 

 from the British list. 



Pimpla nigricans, Thorn. 



Thorn., Opusc. Ent., 754, 28, f ? . 



Mr. Champion has taken, at Box Hill, a Pimpla which 

 I believe to be this species. Thomson says it differs 

 from P. detrita, Holm., in having the tubercles black, 

 and the 5th joint of the tarsi not longer than the 3rd ; 

 besides these points the 1st segment of the abdomen is 

 a little shorter and the aculeus a little longer.
