longer than the 1st (this latter about twice as long as wide) ; 5th 

 rather longer than wide ; metanotum scarcely higher than the 

 mesonotum, and nearly as long ; the transverse ridge of the meta- 

 notum about half-way down the slanting part, very distinct, and in 

 form resembles a VVj at others runs ahnost straight across. First 

 segment of abdomen without projecting spiracles ; sides of post- 

 petiole rather romided and gradually increasing in width, sub- 

 pyriform ; abdomen densely pubescent, pubescence rather more 

 scattered on the apical segments ; aculeus about as long or a little 

 longer than the 1st segment. 



Black; basal half of the antennae, thorax, three first segments of 

 the abdomen, and legs red. Female. 



Var. Like the above, but inner orbits broadly obscure red. 

 Female; length, 5 mm. 



This species comes between 33 and 34 of Foerster's 

 table of Pezomachus. 



This species has been sent to me by Dr. Capron, who 

 took it in the neighbom'hood of Shiere. Another speci- 

 men was sent to me by Mr. Fitch ; this he received from 

 Mr. J. E. Fletcher, and I have taken it myself; and the 

 variety I took at Mousehold, near Norwich, in 1882. 



Pezomachus vulnerans, Fst. 



Mon. d. Gat. Fez., 157, 102, ? . 



Mr. T. E. Billups has taken four females of this 

 species at Headley and Eeigate. 



Pezomachus immaturus, Fst. 

 Mon. d. Gat. Fez. 193, 150, ? . 



I have seen a female which agrees exactly with the 

 description of the above insect, taken by Mr. Billups at 

 Headley. 



Pezomachus vagantiformis, n. s. 



This insect comes next to P. vulnerans in Forster's 

 table, and might be added as " thorax bicoloured" before 

 " thorax red." In general appearance it reminds one 

 of P. vagans, and most probably would have been in- 

 cluded by Gravenhorst in that species. 



Niger, pro- et mesothorace, segmento prime pedibusque rufis. 



Head somewhat narrow behind the eyes ; 1st joint of flagellum 

 scarcely longer than the 2ud, about four times as long as wide ;
