the wing of Rh. falcaria Scudd. from Florissant (Proc. Acad. Amer. 
Philos. Soc. XXXII. p. 206). 
1 specimen. Silstrup (poss. Min. Museum). 
Rhamphidia sp. 
An impression of remains of wings and legs of a cranefly from 
diatom-earth is at hand. The wings are somewhat shorter than those 
of the above named Rhamphidia species, only 10 mm. long. The 
venation of the wing is difficult to observe, the Diatom-earth proper 
not yielding as good impressions as cement-stone. I have f. inst. not 
been able to find any cross-veins preserved, but the preserved veins 
agree so completely with those of R. thybotica that I do not hesitate 
to refer this find to the same genus, though for want of typical 
characters I desist from naming the species. 
1 specimen. Silstrup (poss. Min. Museum). The specimen is the 
one indicated bÿ Mörch as »Termes«. 
Nematocera Polyneura spp. indet. 
In cement-stone procured from Silstrup 2 single cranefly’s wings 
further are at hand, one 19, the other 25 mm. long. The state of 
preservation, however, is so bad that a reference to a genus is im¬ 
practicable. 
Brachyeera Schizophormæ sp. indet. 
A fly’s wing, found in cement-stone at Struer and 10. 5 mm. long, 
in all its characters agrees with the large group of the Schizophorinæ 
to which group it accordingly is referred. Further reference, is, 
however, impracticable, as only the wing is preserved.
