Hymenoptera.—In reference to Hymenoptera, this consti- 
tutes the fourth group in Olassen’s and Povelsen’s arrange- 
ment, but they only mention three species, and I have only 
observed four, and five are all that are stated in Paijkull’s 
appendix. 
Olassen’s and Povelsen’s three species are as follows :— 
1. Tenthredo aculeo crasso. 
2. Ichneumon errator Linnei. 
3. Apis hirsuta nigra thoracis cingulo flavo et ano albo. 
(Apis terrestris Linnzi.) 
These three species, the Sawfly, the Ichneumon, and the 
Humble bee, are all recorded in Paijkull’s appendix, 
namely :— 
1. Tenthredo pratensis, Sawfly. 
2. Ichneumon ovulorum errator, and 
3. Apis terrestris, Humble bee. 
and two other species of Ichneumon as well. 
4, Ichneumon sarcitorius. 
5. = manifestator. 
Two species are thus added to the list in the course of 
52 years, from 1772—1824. And I can do no more than con- 
firm the record of the above-named kinds, as I only obtained 
three specimens of Ichneumonide at Engey, Hatuafjord, and 
Thingvellir, consisting of Ichneumon albicinctus, 9 and, and 
Pimpla sodalis, and Bombus hortorum, the ouly species of bee 
that I found in Iceland, and that is not particularly plentiful. 
I took it at Reykjavik, and managed to secure eleven speci- 
mens at Thingvellir, and subsequently two more at Eske- 
fjord, the only place on the E. coast where I observed it, and 
situate in nearly the same latitude as Reykjavik; Eskefjord 
being 65:5 N. lat. and 14:1 W. long.; Reykjavik being 64°8 
N. lat. and 22°55 W. long. North of these two places on the 
E. and W. coast, respectively, I have not seen the insect. 
To revert to Staudinger, he has set down specifically no 
fewer than 52 kinds of the 61 Hymenoptera, which he men- 
tions as constituting one-fifth of the insects found in the 
island.
