8. IT. Scudder — Miocene Insect-Fauna of Q^ningen. 117 



I have examined with some care his large collection of fossil insects 

 from GEuingen, larger, perhaps, than any outside of Zurich, for it 

 consists of about 3500 specimens, of which fully one-half may be 

 made use of to advantage. Fx'om the better specimens I have 

 separated over four hundred species; and as not a few unpublished 

 forms occur among them, I have thought that a summary acconnt 

 of the collection, with a notice of a very few of the forms, might 

 prove interesting to others, especially as I can add some statements 

 regarding species determined and named by Heer, but not yet 

 published, certain species named by him being accessible, as ah'eady 

 stated, in the Museum at Cambridge, and a few in my own small 

 collection. Altogether I have examined about 4000 specimens. 



The 428 species which I have separated in Mr. Lacoe's collection 

 are divided among the orders as shown in the following table, in 

 which they are placed beside Heer's enumeration of the species 

 which had passed through his hands, and each reduced to per- 

 centages for better comparison : — 



From this table it appears that the relative number of species in the 

 different orders is almost strictly identical in the two enumerations, 

 and enables one to assert with much assurance that in number of 

 species the Coleoptera of (Eningen are vastly preponderant, including 

 about two-thirds of all ; and that first the Hemiptera, and next the 

 Hymenoptera follow, the Diptera lagging somewhat behind, with 

 a feeble and not very differing i-epresentation of Neuroptera and 

 Orthoptera. 



Among the Orthoptera by far the most abundant insect is Heer's 

 Decticus speciosus, of which, including reverses, I have seen sixty- 

 four specimens, all tegmina, and in one case accompanied by a part 

 of the hind wings. There is one specimen (No. 6861) which may 

 be another species, very much smaller than the others, which vary 

 from 43 to 60 mm. in length, while this is only 30 ram. long., and 

 yet is a female. Females appear to be more frequently preserved 

 than males, for of such as can be distinguished, the basal area being 

 sufficiently preserved, there are 26 males to 15 females. It is not 

 very well figured by Heer in his woodcut, since the pale flecks are 

 not round, or only occasionally so, being rather short oblique bars ;
