LIST OF NEUROPTEEA IN BEITISH MUSEUM. 271 



is distinct from P. mimica, though evidently very closely allied. I 

 have an example which agrees exactly with Guerin's description, and 

 which I had originally placed as possibly a sexual form or variety of 

 P. mimica. 



H. ccELiVAGUS, p. 279, 7 = Psychopsis coelivagus, Walker. 



H. HiRTUS, p. 280, S = Megalomus hirtus, L. 



H. LONGicoLLis, p. 281, l2 = Berotha longicollis, Walker. 



H. suBANTicus, p. 282, \3 = Micromiis subanticus, Walker. 



H. OBSCURUS, p. 282, 14 = H. hamuli, L. 



H. POSTICUS, p. 283, \5 = Micromus posticus, W&lkev. c?- Abdominis 

 segmento ultimo ventrali in laminam latam obtusam producto, appen- 

 dicibus spiniformibus. 

 This is probably the same as 3£. insipidus, Hageu. I possess 

 four examples from New Tork.

Under the name of H. nervosus, tvro European species are con- 

 founded ; they considerably resemble each other, save in the anal 

 appendices, v^'hich are strikingly dissimilar. I reserve details 

 for my work on the British JELemerobiidaB, but in the meantime 

 diagnose the special characters as under : — 



H. NERVOSUS, Fab. et auct. Appendices anales fere regulariter curvatae. 

 Tclab. in Europa continent, vulgatissimus, in Anglia aliquanto rarus. 

 I have seen but few British examples. It is probably the species 

 intended by all continental authors. Tor the other I use the name 



H. SUBNEBULOSUS, Stephens. Appendices anales elongatse, latje, rectse ; 

 apicibus truncatis, dilatatis, infra spina elongata, curvata, ad apicem 

 extus unidentata instructis. 

 nab. in Anglia vulgatissimus. 



I have not seen a continental example of this, nor is it known 

 as such by Dr. Hagen. 



The types o^ stibnehulosus (in part), humuli, fuscus, and nervostis 

 of Stephens's "Illustrations" are this species, which is exceedingly 

 abundant in Britain, and very variable.
