210 [September, 



on the Continent, bnt not recorded from Eiii^land. The following 

 will be, accordingly, only a sort of " interim report," in which I shall 

 mention a few of Herr Konow's determinations of my captnres, and 

 add such stray notes as occur to me on particular species. 



1. Tenthredopsis litterata, Geoff. (= Thomsoni, Knw.). — The females of this 

 species (see Cameron, Mon., iv, p. 153) figure in collections under a variety of names, 

 cordata, microcephala,femoralis, &c. They differ widely in colour, but may be 

 known in all cases by the very large hypopygium. Mr. Cameron says he has never 

 seen its real male, that which he had assigned to it in liis first volume being really 

 the male of Coqueberti (= ignolilis. Cam.). I have taken, however, several speci- 

 mens of the true litterata {S) both in Surrey and in Warwickshii-e. It is very 

 unlike any of the forms of its ? , its colour being a pale orange-red with whitish 

 and dusky markings on the head and thorax ; and it differs from all other British 

 species in having the last ventral segment widely emarginate at the apex. 



2. Tenthredopsis nassata, L. — Plerr Konow identifies a ? taken by me this year 

 at Byfleet (Surrey) as nassata, L., var. tutea, F. (= rufata, Knw.). Mr. Cameron 

 (vol. iv, p. 157) says, " neither among my Continental nor British species can I find 

 a specimen which I can identify as nassata, Knw." This species, then, is apparently 

 new to our list. 



3. The nassata of Cameron (vol. i) is named by Konow Raddatzi, n. sp. Of 

 this T have taken several specimens, vvhicli includes Konow's three varieties, inornata, 

 sagmaria, and dorsata. 



•t. Tenthredopsis spreta, Lep. (= obsctira, Knw.). — This species also appears to 

 be " new to Britain." I have taken a (J in Surrey and a ? hi Warwickshire. 



5. Tenthredopsis Coqueberti, Klg. (= ignobilis. Cam.). — This is perhaps the 

 commonest species in Surrey. I have taken it abundantly h\ several localities. 



6. Tenthredopsis campestris, L. (= scutellaris, Pz.). — Konow notes a $ in my 

 collection taken at Virginia Water, " = fidviceps, Steph. !" 



7. Allanttis distinguendus, de Stein. — I have taken this pretty species at Vir- 

 ginia Water. It is new to our list, and indeed has only very recently been discovered. 



8. Dolertis ariceps, Thoms. — I have taken this species both in Surrey and in 

 Warwicksliire. Mr. Cameron seems not to know it as a British insect. It is like a 

 small pratensis, L. {=^ fulviventris, Cam.), but with distinctly shorter antennse. 



9. Dolerus Thomsoni, "Kiwr. (= brevispina, Thoms., non Zadd.). — I have a ? 

 from the neighbourhood of Woking. According to Konow this species is Cameron's 

 anticus ; but to this Mr. Cameron demurs (Mon., iv, p. 164-), considering his species 

 to be the true anticus, Klg., and not Thomsoni. If he is right, we must have both 

 species (anticus and Thomsoni) in England, and the latter will be an addition to 

 our list. 



10. Genus Loderus, Knw. — This genus has been separated from Dolerus to 

 embrace the species with " oblong" eyes. I have taken this year, in this neighbour- 

 hood, all the three British species belonging to it, viz., palmatus, Klg., vestigialis, 

 Klg., and p/'a^oruw. Fall. The last of these is only previously recorded as British 

 in Mr. Cameron's second volume (p. 220) from a capture by Mr. E. Saunders at 

 Chobham.
