CRABRO LUTEIPALPIS. 12? 



side at the apex of the first segment; the third and fourth seg- 

 ments with an ovate macula on each side; the apical margin 

 of the sixth segment yellow, the extreme apex ferruginous. 



The only sex which I have seen is the male ; it was captured 

 by Mr. Dossetor, in Cline Wood, near Swansea. It is undoubt- 

 edly the C. signatus of Wesmael, and I believe also of Panzer ; 

 it is very much like C. dimidiatus ; but the unarmed tibiae, and 

 the spine on the femora beneath, at their base, readily distinguish 

 it. The description of the female is from Panzer and Wesmael. 



C. Div. 3. Abdomen subsessile. Ocelli in an equilateral triangle. 



* Antenna and tarsi simple. Base of the metathorax stri- 

 ated. (Sp. 5-9.)

dibulis flavis aut piceis ; tibiis duabus anticis subtus flavis ;
