SPHEGID.E. I3S 



strongly and somewliat closely punctured ; ^ with tbo 

 anterior legs yellow, except a black line posteriorly, cal- 

 caria black, metatarsi dilated, with a black central band, 

 second and third joints of the tarsi slightly dilated, with 

 their lateral angles black, fourth and fifth black, anterior 

 legs in the ? black, the tibire in front, and the basal joints 

 of their simple tarsi yellowish white, calcaria white, or 

 dusky, intermediate and posterior legs black, the base of 

 the tibiaj and tarsi, and in the c? the front of the interme- 

 diate tibise, pale yellowish ; tibi» distinctly spinose. 



L. 7-8 mm. 



Local, but abundant and widely distributed in the South ; 

 not recorded from Scotland and Ireland. 



C. varius, ie/j. {spinlpedus, Shuck.). — The c? of this 

 species may be at once known from that of the preceding 

 by the simple, not scutate, anterior metatarsi, which have a 

 central transverse black band, and by the pale anterior 

 calcaria; the ?, however, is so closely allied to pahnipes 

 that there is, so far as I know, no very certain character 

 whereby to distinguish it ; the front tarsi are, however, 

 rather narrow, and the metatarsus has its sides parallel, 

 whereas in palmipes its outer margin is slighth' curved at 

 the base, the scutellum has nearly always a central yellow 

 spot, the spines of the mesopleurfe are less developed, and 

 the crenatures of the propodeum deeper. 



L. 7-8 mm. 



Apparently more widely distributed than the preceding, 

 but I have rarely met with it myself. 



C. anxius, Wesm. (exiguus, Shuck.). — Easily distin- 

 guished from either of the preceding, which have tlio 

 mesopleura3 spinose, by the entirely pale anterior metatarsi 

 and the pale tubercles of the S, and the shining smooth 

 basal area of the propodeum in both sexes, which is sur- 

 rounded by much deeper and more clearly defined crennte 

 sulcatures, especially along the base ; the extreme apex of 

 the abdomen is red in both sexes ; the intermediate tibiaa
