Coleoptera and Hemiptera as came readily to hand, while of the 

 Diptera, Hymenoptera and Neuroptera, I took scarcely any, 

 although large numbers of each of those orders were seen. 



Of the diurnal Lepidoptera, or butterflies, over 600 specimens, 

 representing 85 species, were taken in the eleven days spent in 

 the vicinity of Orizaba. During that time it rained two whole 

 and seven half days, so that the facilities for collecting them were 

 none of the best. Of these but eight are found in Indiana, 

 namely, Papilo turnus; three species oi Pyrameis, two of which, 

 atalanta and cardui, are cosmopolitan; the handsome Callidryas 

 eubule, which is very rare in this SlsXe; Jiuionia coenia, also a rare 

 species with us; Terias lisa and Ancyloxypha mimitor, the latter 

 being, there as here, the smallest and one of the most abundant 

 of the Hesperidae. 



During one forenoon I took 168 specimens, over forty species 

 from a single field near the outskirts of the city. It was filled 

 with brilliant flowers, and the margin, where occasional clumps 

 of bright red flowers grew, was a favorite lurking place for many 

 of the larger and rarer kinds. One of the most striking species, 

 on account of its size as well as its so-called ' ' protective mimicry, ' ' 

 was a large and handsome Callidryas light yellow above and of 

 a greenish hue beneath, which, when resting with folded wings, 

 could scarcely be distinguished from a leaf so closely did the 

 color and the prominent veins on the underside resemble those 

 of a leaf

ELEMENTARY ENTOMOLOGY. 



LEPIDOPTERA-HETEROCERA (Moths). 



By Prof John B, Smith, New Brunswick, N. J. 



Following the Sphingidae in our catalogues and lists come the 

 Sesiidae. They were originally included with the clear winged 

 Sphinges on superficial characters, and, though long since sepa- 

 rated from them, are yet, as a rule, placed next to them. In 

 fact, except for the superficial resemblance, there is nothing war- 

 ranting any close association of the two families. So far as I am 

 aware the larvae of the Sesiidae are borers, living in roots, stems 

 and trunks of vines, shrubs and trees, sometimes maturing two
