Moschler discusses the systematic position of the genus of zyg- 
enid moths, Triprocris. At the meeting of the Washington 
Entomological Society for Feb, 11, Mr. Schwarz said that among 
the many forms of secondary sexual characters in the Coleop- 
tera, some would likely be found to be analogous in function to 
those in the Lepidoptera. He referred more particularly to the 
tufts of hair in the mentum of Trogosita, and those on the ven- 
tral segments of the male of Dermestes. Differences in the ves- 
titure of the sexes are known to occur, e. g., Hoplia, where the 
male has scales and the females only hairs; but in this case it is 
hardly possible that we have to do with odoriferous organs.

MARKINGS or Antmats.—Eimer has advanced the view that 
the markings on animals are primitively longitudinal stripes, 
r 
ontogeny of many animals. Dr. W. Haacke controverts this 
view from the study of an Australian fish, Welotes scotus. The 
adult fish is marked by eight longitudinal black bands; young 
specimens have in addition a row of clear transverse bands, which 
disappear when the fish attains to maturity.— Journ. Roy. Mier.

nine survey steamer Jnvestigator. They belong to the genera 
ma 
Amathia, Ethusa, Eucephaloides (n. gen. allied to Collodes Stimp- 
son) and Lyreidus, of which the last named (Z. channert) is espe- 
cially interesting on account of the rudimentary condition of the 
es. 
These organs are unequally reduced, the cornea of the left — 
being of the normal form and extent, but opaque and devoid of 
all traces of facets, as in Munidopsis, Orophorhynchus, Nephrop- 
and other blind forms of the deep sea, while,that of the right 
Is entirely aborted, its place being only indicated by a small 
Smooth spot marked out by the transparence of a lead-colored 
Pigment similar to that which is seen through the integument 
around the base of the left eye. This interesting brachyuran, 
which 1S at once distinguished from the Japanese and American ae
