not for what reason Gray's name is deposed in favour of rnficollis, 

 Rambur, to which it is long anterior. 



H. MACULiFERA, p. 203, 3:=C. macuUpennis, Gray, 5 . 



H. SINENSIS, p. 203, 4=Chauliodes sinensis. Walker. As this name 

 is already employed in Chauliodes, I propose to change it to Bow- 

 ringi. 



H. GUTTiFERUS, p. 204, 5=Chauliodes guttiferus. Walker. No locality 

 is given, but examples have been since received from Australia. 



H. DUEITATUS, p. 204, 6=Chauliodes californicus, Walker, 5- 



H. iNDECisus, p. 204, 7=Chauliodes rastricornis, Rambur, §. 



H. ANTicus, p. 205, 8=Chauliodes sinensis. Walker, 5 . 



H. DivERSUs, p. 205, 9=Chauliodes diversus, Walker. 



H. PRASiNUS, p. 206, 10. I cannot imagine what fatality induced 

 Mr. Walker to place this insect (described as Chloroperla prasina by 

 Newman) among the Sialidcp, with which it has nothing in common. 

 It is somewhat allied to Eusthenia of Westwood ; and I recently pro- 

 posed for it the generic term Stenoperla ; vide ' Trans. Ent. Soc' 

 ser. 3. vol. v. p. 354. 



H. TESTACEUS, p. 206, ll=:CorydaUs testacea, Rambur. 



II. HiEROGLVPHicus, p. 206, \2=Corydalis hieroglyphica, Rambur. 

 This and testaceus are very closely allied, although coming from such 

 opposite localities. 



H. ALBiPENNis, p. 206, \3=:Corydalis albipennis. Walker. 



H. cosTALis, p. 207, \4=Corydalis costalis, Walker. This species is 

 ill-placed in Corydalis, and does not agree well with Chauliodes, on 

 account of the numerous transverse veinlets. It seems to vary much 

 in the markings, probably according to the degree of maturity attained 

 by the individuals. The, as yet, not rediscovered Hemerobius grandis, 

 of Thunberg, from Japan, should be somewhat allied. 



Genus Corydalis, p. 208. 



C. CORNUTA, p. 208, 1. The example from Columbia=C. armata, 

 Hagen {cornuta, Rambur) ; the two other specimens are the true 

 cornuta. 



Genus Eaphidia, p. 209. 



I leave the exact determination of the species of this genus for 

 a future occasion, when I shall have worked them oi^t for my 

 ' Monograph of the British PJanipennia.'' The species are very
