 bristly, barbuled coarsely, black, a few 

 longer hairs posteriorly. Later there is a

Stage IV. Lobes of head shining black, 

 clypeus pale yellowish ; width i.i mm. Body 

 blackish brown, not so dark as usual, no 

 marks except a very faint paler straight dor- 

 sal and a lateral line (below ii) . Warts shin-

 Hair as before with the addition of two very 

 long slender white hairs from joint 13. Later 

 the pale marks around warts iii are faintly 

 reddish. 



Stage V. Head pale brownish, a black 

 shade on each lobe in front, mouth brown, 

 eyes large, black; width 1.55 mm. Body 

 black, the warts shining, large with stiff 

 black hairs, a pair of long (12 mm.) white 

 ones posteriorly. No distinct marks; a faint 

 whitish dash below wart iii, fine pale dorsal 

 and subdorsal (below ii) lines; lateral area 

 paler than the dorsal, the bases of warts iii 

 to V slightly reddish. 



Stage VI. Head >,hining black, bases of 

 antennae and line above mouth whitish; 

 width 2.2 mm. Body all black, velvety; 

 warts shining, the bases of ii to iv faintly 

 reddish under a lens, no marks visible to the

 the basal rings of the warts dull luteous, 

 warts shining, no other marks. Hair very

 head are brownish and later the antennae 

 and line above the mouth becomes pinkish. 



The larvae hibernate in this stage. The 

 growth is slow. The eggs hatched toward 

 the end of June, the last molt took place 

 between August 24th and September 12th in 

 different larvae and hibernation began soon 

 afterward. 



Food plants various low plants. 



PINK LOCUST.\RIANS. 



A SPECIMEN of .Ainblycoyypha obloiigifolia 

 of a vinous color was sent nie in 18S6 by 

 Mrs. Sidney L Smith who took it Aug. 9, at 

 Woods' Holl. It was dead when it reached 

 me but had been kept alive some time. All 

 the green parts including both tegmina and 

 wings were tinted of a uniform color except 

 that the thickened green flecks of the normal ' 

 tegmina and the lateral carinae of the pro- 

 notum were fuscous. So too were the eyes, 

 but the antennae, except the extreme base, 

 were luteous like the ordinary form. The 

 specimen was a ? and the color extended to 

 the ovipositor of course, the denticles of 

 which were fuliginous. 



Two other specimens ((J ? ) of the same 

 species were also taken at the same place bv 

 Mr. Richard Rathbun and Prof. A. E. Verrill 

 on Aug. 29, 18S6, and were examined while 

 still living. Tlie ? is of a pale coral red 

 verging on magenta, the abdomen a shade 

 paler, while the $ is of an orange red. The 

 tegmina of the $ are of a very clear color 

 with scarcely a single fleck of brown while 

 those of the J are much dotted (for Ambly- 

 corypha) with brown and longitudinally 

 flecked with yellow, while the stridulating 

 field is almost entirely dull brown, and an 

 obscure patch of the same color more distinct 

 on one side than the other appears near the 

 middle of the outer half of the tegmina near 

 the upper margin. In both the palpi are of 

 the color of the body, but the eyes are green 

 and the antennae of the normal luteous. 

 The lateral carinae of the pronotum are 

 luteous in the ?, fuscous in the J.
