laterally, it was well-rounded, broadest just 

 above the little-flattened base, with low. 

 longitudinal, raised ribs connected by deli- 

 cate, transverse ridges. The longitudinal 

 ribs were sixteen in number, of which four 

 pairs, each consisting of two ribs uniting 

 near the summit at a sharp angle, enclosed 

 within the four loops thus formed from one 

 to three shorter ribs. Diameter, 1.27 mm. 

 Nine days after deposition the egg began to 

 hatch, one rainy forenoon, having become 

 darker and finally of a brassy color, the shell 

 being transparent between the rib.s. The 

 larva intermittently gnawed an opening at 

 the micropyle, then started a second hole 

 which at length coalesced with the first one. 

 Although the aperture thus formed was large 

 enough, the larva did not emerge but began 

 two moi'e openings on the side of the egg- 

 shell. The shell had become shrunken and 

 distorted, meanwhile. I watched the progress 

 of hatching, or rather, lack of progress, for 

 two days, at intervals. The caterpillar's 

 method of work was to eat for ten minutes 



and then to rest for forty-five, and when I 

 made investigations during an unusually 

 long rest, I found that the larva had died. 



At Prospect Hill, Waltham. Mass., June 

 10, 1S94, I enclosed a suspicious acting T. 

 Jimenalis alive in a small pasteboard box in 

 which she soon laid a single egg, the hatch- 

 ing of which I did not witness, however. 

 This female also had been fluttering about 

 seedling white-oaks in an inquisitive way.

Notes. — A new monthly journal of ento- 

 mology has appeared in Tokyo, Japan, under 

 the title Konchu Gaku Zasshi, or Journal of 

 Insect Science. The fii'st number was issued 

 in October last and is wholly in Japanese 

 excepting an English title and tlie statement 

 that the plate represents insects injurious to 

 rice and mulberry.

Scudder's Brief Guide to the Com- 

 moner Butterflies. 



By Samuel H. Scudder. xi + 206 pp. 



i2mo. $1.25. 



An introduction, for the voting student, to 

 the names and something of the relationship 

 and lives of oiu" commoner butterflies. The 

 author has selected for treatment the butter- 

 flies, less than one hundred in number, which 

 would be almost surely met with by an in- 

 dustrious collector in a course of a year's or 

 two year's work in our Noi-thern States east 

 of the Great Plains, and in Canada. While 

 all the apparatus necessary to identif^' these 

 butterflies, in their earlier as well as perfect 

 stage, is supplied, it is far from the author's 

 purpose to treat them as if they were so man^' 

 mere postage-stamps to be classified and ai'- 

 ranged in a cabinet. He has accordingly 

 added to the descriptions of the different spe- 

 cies, their most obvious stages, some of the 

 curious facts concerning their periodicity and 

 their habits of life. 



Scudder's The Life of a Butterfly. 

 A Chapter in Natural History for 

 the General Reader. 



ByS.\MUEi, H Scudder. 1S6 pp. i6mo. 

 $1.00. 



In this book the author has tried to preseni 

 in untechnical language the story of the life 

 of one of our most conspicuous American 

 butterflies. At the same time, bv introduc- 

 ing into the account of its anatomv, devel- 

 opment, distribution, enemies, and seasonal 

 changes some comparisons with the more or 

 less dissimilar structure and life of other but- 

 terflies, and particularly of our native forms, 

 he has endeavored to give, in some fashion 

 and in brief space, a general account of the 

 lives of the whole tribe. Bv using a single 

 butterfly as a special text, one may discourse 

 at pleasure of many : and in the limited field 

 which our native butterflies cover, this meth- 

 od has a certain advantage from its simplicitv 

 and directness.
