Crabro inininius Pack. 



The % of this species has the fore femora aud mesosternuru clothed 

 with long, white hair, thus differing from the other species of the 

 group, Avith the exception of pictipes, which is larger, has the cly- 

 peus and scape entirely yellow and the base of the middle segment 

 excavated. In S minimus the base of the middle segment is as 

 described by Packard, having a row of minute foss?e. 



An examination of types shows the pi'onotum to be angular at 

 the sides, notwithstanding Packard's statement to the contrary. 



Crabro iiiiiciis Pattou. 



This species forms a group differing from group insolens by the 

 middle segment having a distinct enclosure above ; by the epimerum 

 mesothoracis being strongly ridged, an unusual character for species 

 of this section of Crabro, and by abdomen, which is said to be clav- 

 ate. The abdomen is missing from the unique type kindly loaned 

 by Mr. Patton. The hind legs robust, their tibise strongly clavate 

 and strongly serrated externally. Recurrent vein received by the 

 marginal cell in the middle. Pronotum sharply ridged, with a small 

 tooth laterally. 



This may be the 9 of group planipes, of which the males only 

 are known. 



In my paper the following errors, typographical and otherwise, 

 occur which should be corrected : 



Page 129, line 5, for includes read include; line 10, for peninsular read peninsula. 



" 153, line 35, for 1 read 7. 



" 159, line 19, for longitudial read longitudinal. 



" 163. line 9, for munficola read monticolits. 



" 167, line 14 (from bottom), for form read fore. 



" 178, line 16 (from bottom), for is read are. 



" 180. line 21, for and read or. 



" 181, line 12 (from bottom), for anterio read antero. 



" 196, line 25, for nigror read nigrior. 



" 196, line 14 (from bottom), for nigror read nigrior. 



" 212, line 9 (from bottom), for stirpicola read stirpicoliis. 



" 218. line 20 (from bottom), for nii/ror, read nigrior. 



" 220, line 20, for denticnJatus read pauper.

" 222, lines 5 and 12 (from bottom), for tibiai read tarei. 



" 225, lines 28 and 29, for metatliorax read middle segment. 



Througbout my paper the termination of the Latin adjective after such nouns 

 as epimerum aud episternum should be e instead of is.
