Grenier (Ann. Soc. Ent. Er. 4” serie, tome iv. pp. 137-140) 
has some observations on the traces of eyes in beetles reputed 
blind. Having found indications of eyes in AnophthalmuSj he 
examined the other blind beetles, and found in Aphmnops an 
excessively minute surface marking the position of the visual 
organ. In Leptoderm, Adelops^ &c., no trace of an eye can be 
detected ; but in Glyptomerm cavicola there is a very small one, 
presenting no facets, but distinguishable by its pale colour. He 
suggests that in many cases the internal portions of the organs 
of vision may be sufficiently developed to enable these insects 
to perceive the faint rays of light that may find their way into 
the caverns; in others, however, it has been found that the 
visual nerves are either wanting or rudimentaiy, indicating that 
the sense of sight can hardly be exercised by these. Further 
observations on tlie anatomy of this part of the nervous system 
in the blind beetles inhabiting dark caverns and ants^ nests are 
very desirable. 
Stierlin (Berl. entom. Zeitschr. 1864, p. 143) remarks that 
the Coleopterous fauna of Sicily presents but a small number of 
peculiar species, certainly fewer than that of Corsica and Sardinia. 
It presents the closest agreement with that of southern Italy, next 
with Sardinia, Corsica, and the south of France, and also with 
the opposite coast of Africa. It differs widely from the fauna 
of Greece, Dalmatia, and Spain; but many of Die species of the 
mountainous districts occur also in the Pyrenees. The species 
common to Sicily and central Europe generally present some 
differences of size, form, sculpture, or colour. 
Baudi (Berl. ent. Zeitschr. 1864, pp. 195-233) gives a list of 
303 species of Colcoptera belonging to the families noted below, 
found bj^ Truqui in Cyprus and Asia Minor. The numbers in 
the different families are as follows : — CicmdelidcRj 5; Car abides , 
179; Dytiscides, 18; GyrtnideSy 6; Palpicornta, ^0 •, ^ilphaleSy 
12 ; Trichopterygia, 6 ; P>capliidiVia, 2 ; Histeridm, 46. Several 
of the species are described as new, and one of them as the type 
of a new genus {Cymbionotum in Carabidie). Of the known 
species many varieties are described, and the text and notes 
contain remarks on synonymy by the author and by Schaum.
