into Psocus as restricted by Kolbe, others would fall into Amphigerontia, 

 Kolbe (one even presenting the condition seen in A. hifasciata, Latr.) ; 

 and the form of the posterior marginal cellule is also very variable. 



Psocus bipunctafus, L., was once found by Meyer-Diir in numbers 

 under a stone in Switzerland, not in company with ants. It is possible 

 there may be no real connection between the ants and iV. rhenanus ; 

 but, at any rate, the latter were not molested by the former. Stone- 

 turning will probably become a practice with Entomologists in search 

 of rare and new forms of Psocidce. 



Peeipsocus alboguttatus, Dalman, & P. pupillatus (Dale), "Walker. 



Two perfectly distinct European (and even British) species are 

 confused under these names, the names themselves, in their original 

 signification, representing one and the same species. 



Some time ago I felt certain we had two species in England, and 

 communicated the materials to Herr Kolbe, who agreed with me. 

 Latterly, in the " Entomologische Nachrichten," viii, pp. 211 — 212, he 

 separated them as P. alboguttatus and pupillatus, but in error, and his 

 alboguttatus stands in need of a new name. I briefly characterize the 

 two species, with notes, &c. 



1. P. ALBOGUTTATUS, Dalman (pupillatus [Dale], Walker ; Hagen ; I 

 Kolbe : alboguttatus, McLach., olim, part. ; Spangberg : stria- 

 tulus, Steph., part., sec. collect., fiec Fab.). 

 Much, smaller than the succeeding species, the anterior wings only expanding to 



5 — 63 mm. The head and thorax darker 

 brown (nearly black in life). Anterior 

 wings very dark grey (nearly black in life) ; 

 in nearly all the cellules and areas the dark 

 (/round is represented by a papillate spot 

 surrounded by tohite ; a double sub-apical series of lohite spots. 



Has been taken in England by the late Mr. Dale and by myself; 

 I found it commonly on the 4th July, 1873, near Weybridge, by beating 

 bushes of Calluna that overhung a high bank. Switzerland : I found 

 an example in the Foret de Pfyn, Canton Valais, on the 10th July, 

 1882, amongst Pinus sylvestris. Ehenish Prussia. Sweden ; accord- 

 ing to Dalman and Spangberg. Madeira ; Wollaston. 



This is undoubtedly Dalman's alboguttatus, as is proved by the 

 following words in his diagnosis : " alse nigrae, maculis discalibus ma- 

 joribus albis G, puncto nigro inscriptis, vel sub-ocellatis ; intra mar- 

 ginom apicalem puncta 10 minora alba, duplici serie ordinata." It is 

 also pupillatus (Dale), Walker, as represented by the single specimen
