. Annual report of the Commissioner of Agriculture ... Agriculture -- New York (State). ?L. pratensis, Fourth Stage. Fourth Instar.—Body, larger; elongate-ovate; broad and long. Lateral margins narrowest behind the head, gradually widening to the third segment of the abdomen, then abruptly to the anus. Integument microscopically hairy. Abdomen, pyri- form. Head, small; quadrangular, lateral margins rather sharply converg- ing at apex. Eyes compound. Hairs regularly placed as in previous instars. Prothorax, equal to the head in length; sub-rectangular; lateral margins only slightly divergent; hind margin somewhat wider than the transverse diameter of the head through the eyes. Mesothorax, about one-half longer than the prothorax; slightly wider than the metathorax; lateral angles projecting nearly to the second abdominal seg- ment. Metathorax, somewhat longer and narrower than the preceding seg- ment; hind margin at the lateral angles reaching the middle of the second abdominal segment. Appendages.—??Antenna, strong; joint I is about one-half the length of joint IV; joint III is four-fifths the length of joint II, which is the longest member. Legs, long and slender; femora of about the usual proportional length; femora III about one-fifth longer than femora I; tibiae I about one-half the length of tibiae III, which are about one-third longer than tibiae II. The tarsi are as usual. Hairs on the body are placed as usual, but are somewhat smaller. Color, green throughout; wing pads often lighter yellow; top of head, tips of wings and median abdominal spot Fifth Instar.— Body, larger; elongate-oval; lateral margins nar- rowest behind the eyes, gently curved to caudal margins. Meso- thorax and abdomen of about the same width. Hairs less noticeable than before.
