Phengodini.—The American NATURALIST for September, p.

observed in Phengodes laticollis Horn., by G. F. Atkinson. From 
the descriptions of the form of the female, its mode of life, and 
also of the egg, is but a counterpart of all these stages observed 
in Zarhipis. Indeed, without more definite and microscopic 
details, the descriptions of these stages in Phengodes would do 
quite as well for Zarhipis, showing how close these genera are. 
On page 855 the description of the egg of Phengodes appears, 
and it applies so well to that of Zarhipis as to make me think 
yellowish; size, 4 mm. diameter. They are not much unlike 
small slugs’ eggs. As the sexes are so much unlike in form, 
Mr. Atkinson, on page 855, says, “ The luminosity in this case 
is of sexual significance, attracting the males at night.” This is

in habit. The composition of the powerfully-diffused pes

both correct, that Zarhipis possesses the double habit of simply
