74 FIELD AND FOREST. 



Larva about two inches in length, head reddish yellow, wiLh a tri- 

 angular black spot in the centre and two black spots on each side ; 

 mouth parts black. Color, greenish tinged with blue, and veined 

 with lines of white radiating from the spiracles, which together with 

 lateral lines, are also white ; under side whitish, tinged with green. 



On the ninth ring there are two spots just under the dorsal stripe, 

 showing larger and more plainly before the last moult ; last pair of spir- 

 acles larger than others. 



Pupa about 1.37 inch in length, each end terminating in a point; 

 that from the head projecting in front so as to form a kind of horn. 

 An appendage, supposed to be the sucking tube, extends, free, from 

 the end of the wing-case nearly half an inch beyond the tail. Color, 

 greenish-white at first, as if covered with a bloom, and with two rows 

 of black dots (four on each ring J upon the back. The color, however, 

 changes, becoming darker as the insect matures. 



Mantis Carolina. — One morning in January we were much inter- 

 ested in watching the hatching of the eggs in an egg-cluster of Matitis 

 Carolina, commonly known in the Southern States as rear-horses. 

 The cluster of eggs, as deposited by the female, were placed in the 

 fall, in a wardian case filled with ferns, in the rooms of the Entomo- 

 logical Cabinet, at the Department of Agriculture, and the early 

 hatching was doubtless due to the uniformly warm temperature of the 

 room. 



Our attention was first attracted one morning by a number of small 

 yellowish points above the ridged portion of the egg-clusters, when sud- 

 denly, to our suprise and delight, one by one the little points seemed 

 to rise or glide out of the crevices, so to speak, in which they had lain, 

 without any motion of their own ; in fact, as they tapered down to a 

 point, regularly, from the head, it seemed as though the cell walls had 

 been suddenly compressed, and had forced them out. Fairly hatched, 

 and lying helpless on a projecting ridge of the sash, we had a fine 

 view of them through the magnifying glass, which -clearly revealed 

 their large triangular heads and bead-black eyes, and their slender 

 legs, which were pressed close to the side of the body. The whole 

 was enclosed in a delicate membrane, hardly visible even with the 

 magnifier, and altogether they seemed more like the pup^e of some 

 species of flies we have seen, than juvenile "rear-horses." 



A moment of helpless inactivity, and then all those six little legs
