Analysis of Thomson’s “ Opuscula Entomologica,” Fascc.i and iii—Since the 
completion of his very able work on Scandinavian Coleoptera, C. G. Thomson has 
commenced the publication of a series of papers on Swedish insects of several 
orders, under the title of Opuscula Entomologica. Except that they are confined 
to the Scandinavian fauna, these much resemble in their scope Mulsant’s well known 
“Opuscules.” Two fasciculi have already appeared, consisting together of 304 
pages, and containing fifteen papers ; the first fasciculus bears the date of 1869, the 
second of 1870. As the contents of these fasciculi are of the greatest interest to 
British entomologists, a short account of them will doubtless be acceptable to the 
readers of this Magazine. 
The first paper is on the genera of Swedish bees ; 27 genera are characterized, 
of which several appear to be new, but as no authors names are attached to any 
of them, I can give no further particulars. The second paper is on the Coriwe of 
Sweden ; 24 species are described, of which six are new; no reference is made to 
any of Messrs. Douglas and Scott’s species, and it is probable that some, at any 
rate, will prove to be identical with these. The third paper describes the six 
Swedish species of the genus Celiorys; four appear to be identical with British 
species. Next comes a paper describing the Swedish species of Iassus ; 72 species 
are described, three being considered new. The fifth paper describes the genera 
and species of Swedish Vesparie, both the social and solitary wasps being included 
under this name. No less than 22 species of Odynerus are described, and of this 
number the author appears to consider eight as previously undescribed. The sixth 
paper is also devoted to the Hymenoptera, and describes the species of Epeolus, 
Nomada, and Sphecodes. Of the first, two new species are described; and of 
Nomada six, and of Sphecodes four, novelties are brought forward. The seventh 
paper describes the genera and species of the Linneean genus Chrysis; six genera 
and 28 species are treated of, the new species in this case are two in number, and 
belong to the modern genus Clirysis. Then comesa paper for the dipterist, describ- 
ing the Swedish species of Pipunculus, 25 species (three new) are given. The 
ninth paper enumerates species ef Coleoptera new to the Swedish fauna: these are 
Bembidium Clarkiit, Haliplus transversus (n. sp., near fluviatilis) ; Ilybius enescens, 
hitherto confounded with guttiger, Gyll.; Anacena carinata, n. sp. (=variabilis 
milt); Philonthus lucens, Heterothops nidicola, n. sp., Stenus glabellus, n. sp., 
separated from carbonarius, Gyll., Cyphea curtula, Atheta incognita, A. vilis, A. 
atomaria, A. palleola, A. canescens, A. ischnocera, n.sp., A. glabella, n. sp., A. levana, 
Tachinus proximus, Choleva cisteloides, Trichopteryx fucicola, Cis puncticollis, un. sp., 
Trachys pygmea, Orthopleura sanguinicollis, Dasytes rugipennis, Dircea 4-guttata, 
and Bagéus angustulus, n. sp. The tenth paper describes the Swedish species of 
Andrena, thirty-nine in number, whereof six are new. The eleventh paper treats 
of Swedish Crabronida, four novelties in the genus Crabro being described. The 
next article is a monograph of the Swedish species of Lygeus; these are 57 in 
number, of which Thomson considers five new. The thirteenth paper is devoted 
to Hymenoptera, and describesthe genera and species of Swedish ‘ Rofsteklar’ (fossorial 
Hymenoptera) : two new species of Pompilus, two of Pemphredon, and one of Tachytes 
are brought forward. Then come descriptions of the Swedish Bombi and Apathi, 
the former 21 in number (one new), the second five. The fifteenth aud last paper 
is a revision of the genera and species of Swedish Tenthredinide ; among their 
number several novelties are enumerated.
