Crabro is a group of fossorial insects varying so much in 

 structure, that MM. St. Fargeau and Brulle have formed 

 them into 1 1 geneva, the EngUsh types of which I shall subjoin, 

 referring to the Srd vol. of the Ann. de la Soc. Ent. for their 

 characters. Mr. Shuckard has given a very able synoptic 

 table, as well as elaborate descriptions of the species, a list of 

 which will be found in the Guide. I wish to observe that the 

 pellucid spots on the spoon of the masculine fore-legs are co- 

 vered with a membrane, and it will be seen by the dissections 

 of the trophi that there are ample grounds for establishing the 

 genus Wiopalum. These insects are often found upon um- 

 bellatse, and some of them undergo their metamorphoses in 

 decayed trees. Latreille says that C. cribrarius provides for 

 its larvae with a Pyralis (Tortrix) that lives upon the oak : 

 other females nourish them with Diptera.

12^. varus Curt. — comptus aS^. Farg.? v. 3. |j. 705. 8. 

 Male black, minutely punctured and hairy: aiiteniise 13-jointed, with the 

 Srd and 4th joints dentate, scape yellow beneath, clypeus and inner mai'- 

 gin of eyes silvery ; crown convex : metathorax rugose : abdomen witli 

 5 yellow spots on each side, the 1st pair, which is the largest, being on 

 the 2nd segment ; those on the 6th are united : legs black, anterior thighs 

 with a )'ellow streak beneath in the anterior, the otiiers with a spot at the 

 apex ; tibice black, intermediate slender and crooked, the others yellow 

 outside ; tarsi yellow, hinder brown, apical joint blackish ; length 3 lines. 

 I took a male at Horning in Norfolk the 24th of June, and 



Mr. Shuckard has 2 from Scotland. The small size and 



crooked slender and black intermediate tibiae, distinguish it 



from C. Xyhirgus.
