Folio. Continnation of Errata from Vol. III. 



SHI'' last line but one, ybr Aira precox (Early Hair-grass) read Carex dioica mas 

 (Common Separate-headed Carex). I regret that in their journey from Cam- 

 bridge the labels were displaced, which led to a transposition of the names. 



389 Agriotypus armatus. Mr. Wailes in a letter says, " I took a specimen on the 

 shore of Derwentwater (amongst the small stones so characteristic of lakes 

 amongst the older strata,) in April last. It is a female." 



395 The characters of $ and ? added to the iigures of the antennffi in the Plate, 

 have been accidentally transposed, and the signs in the description, lines 14 and 

 17, have been made to correspond, to prevent further mistakes. 



419^ Nomada Dalii was taken at Charmouth, Dorset, May 12, and not in the New Forest. 



439 line 34, after centre add and produced behind like a scuteUum which is sometimes. 



472^ line 25 for sublunulate one read sublunulate spot. 



VOL. IV. 



129'' line 4 from the bottom, ybr Llandidus read Llandidno. 



202'' ybr Betonica officinalis, &c. read Prunella vulgaris (Self-heal). 

 ib. last line but 4. for Dundingston read Duddingston. 



357 Anthophora Haworthana. Since this species was published I have received 

 a pair from Dr. Howitt, who takes the sexes near Nottingham : the female is 

 so similar to that of A. retusa, that the only difference I can discover is in the 

 colour of the spurs to the tibia;, which a,Te ferruginous, and not dusky or black 

 as in J. retusa. 



448 Lasioylossnm tricingulum. I find that I possess the female of this curious insect. 



616 tine 25, after crossing, add with a tooth at the extremity of the inner margin. 



632'' last line but one, /or Queckit read Quekett. 



652 line ^2, for clavigerum read clavicerum. 



712*" line 'il for Dorchester read Doncaster. 



732 Agrion ruhellum Van. Lin. : the var. figured is A. avratiliacus of Jlons. de 

 Selys-Lougchamps.
