In this paper Stal publishes his identifications of the Fabrician 
lUiynchota from the types preserved in tlie museums at Copen- 
hagen and Kiel. The portion published in 1868 includes the 
Heteroptera.

This paper contains synopses of the genera of Tetyrida, Aso- 
pida, Pentatomida, Acanthosomatida, Alydida, and Coreida, re- 
presented in America, of the genera of Discocephalida, Pla- 
coscelidida, Smiliida, and Darnida, and of the Asiatic and Aus- 
tralian genera of Pentatomida. 
It is to be regretted that in this, as in other synoptical papers 
published by him, Stal does not in any way indicate those 
genera which are newly characterized; hence none but those 
specially engaged in the study of the Rhynchota can ascertain, 
without much trouble, what are to be regarded as new genera. 
The Recorder fears that he has failed in some instances ; but life 
is too short to be wasted upon such investigations, which the in- 
sertion of a few asterisks or similar marks by the author might 
render quite unnecessary. Both in this and, especially, in the 
preceding paper no types are indicated for a great many of the 
proposed genera ; in the Recorder's opinion a genus can no more 
exist without species, than a species without individuals, and all 
genera under which no species are described or cited ought to 
be expunged from our lists.

General Notes. 
Douglas and Scott piiblivsh (Ent. M. Mag. v.) a list of species of this order 
taken in Palestine and Syria by Cambridge. The list includes 46 species of 
Heteroptera and 2 of Homoptera. Of the former 14 are described as new, 
and 3 of these as the types of new genera. 
Boisduval (Ent. Hortic. pp. 217-338) describes the general characters of 
this group, and the habits of those forms which commonly occur in gardens. 
He treats in considerable detail of the Aphididfe and Coccidae. He includes 
Thrips in this order (I c. pp. 231-235). 
Frauenfeld (Verb, zool.-bot. Ges. in Wien, xviii. p. 293) gives a list of 10 
species of Heteroptera collected by him on the Nicobar Islands.
