Afnhlychila. Such Orthoptera as they are able to seize, they eat with the 

 greatest avidity, but it is very rarely that they are able to catch any but 

 the slow moving walking-sticks^ They also devour a great many ants. 

 They never feed on effete or decayed matter. 



A dozen or more, when confined in a small space, will rarely injure 

 one another, but are readily kept captive, eating any fresh animal food 

 and even thriving on fresh meat. Their appetite is by no means small 1 

 They never heed an observer or collector till touched. 



The males in the great majority of cases are larger than the females 

 and may be readily distinguished by the sharp-pointed trochanters of the 

 hind cox?e. 



DESCRIPTION OF THE PREPARATORY STAGES OF 

 PHYCIODES HARRISII, SCUDDER.

I received, 25th June, from Mr. C. P. Whitney, New Milford, N. H., a 

 cluster of about 50 eggs of this species, laid on the under side of a leaf 

 of Dipiopappus umbellatus, date of deposition not stated. The larvse 

 hatched 28th June. The food plant not being obtainable by me, I gave 

 them leaves of Chelone glabra, on which phaeton feeds, but so long as 

 the least bit of the dry leaf of Dipiopappus on which J:hey hatched 

 remained, the larvae declined the Chelone, and then after starving many 

 hours they attacked it vigorously. But, meantime, for want of proper 

 food, several died. They manifested alarm just as do the larvae of nycteis 

 and phaeton, by a jerking motion of the body from side to side, the last 

 segments being fixed to the leaf, and all the larvae jerking together. This 

 is contrary to the habit of tharos so far as observed, nor have I seen it in 

 other species. On 2nd July the first moult was passed, and the larvae 

 now utterly refused Chelone, although gnawing the edges of a bit of white 

 paper in their hunger. I gave them Aster and on this they fed readily to 

 the last, eating any species indifferently. On 7th July they were passing 

 second moult, and on 12th and 13th, the third moult. Shortly after this
