to fresh food-plants they evinced a decided tendency to creep 

 under the curled-up edges of withered leaves. Feeding and 

 movement gradually ceased completely, and they remained 

 clinging motionless to the leaves. When disturbed, they rolled 

 up, like a watch-spring, moved about a little and then resumed 

 their dormant attitude again. It was also observed that as the 

 leaves withered, the larvae dropped off and, if possible, attached 

 themselves to the stems. In the breeding-cages, they adhered 

 to the edges of the plant-pot. In the field, they fell to the 

 ground among the dead leaves, and under these they passed the 

 winter in a dormant condition. In color, they match exactly 

 that of their environment of dead leaves, but a large number 

 seemed to retain their original leaf-green tint. In the beginning 

 of September, the larvae had apparently contracted a little and 

 now measured only 7.00 mm. long by 1.50 mm. broad. This 

 apparent shrinking was probably associated with insufficient 

 moisture under breeding conditions. 



The over- wintering larvae first begin to show signs of activity 

 in March when the Trautvetteria sends up its fresh shoots. The 

 growth of the larvas then proceeds quite rapidly until the larvae 

 pupate in the middle of May. 



In many respects, the details of the larval life-history agree 

 with those of the species glahrata of the closely allied genus 

 Liogma, as described in the admirable paper of Dr. Mueggenberg 

 published in 1901. Mr. Alexander {loc. cit., p. 106) quotes this 

 author as having found the larva feeding on the moss Hypnum 

 squarrosum Brch. and Schp. in the wet, grassy spots of woods 

 in the environs of Berlin. According to Mueggenberg, the larva 

 moults several times, probably at least eight, which Alexander 

 says is the number determined for Phalacrocera by Bengtsson. 

 As to the exact number of moults of the larva of C. sple?idens, 

 the author is unable at prsent to make a definite statement. With 

 tolerable certainty, it can be stated that close observation revealed 

 only one moult as occurring before hibernation and two after, the 

 last being the casting of the larval skin previous to pupation. 

 In the penultimate stage, the larva measures 15.00 mm. and the 

 full-grown larva 17.00 mm. The duration of the various larval 

 stadia, except that of the first, cannot be stated with any 

 degree of accuracy, but it is hoped that it will be possible to 

 decide this, as well as the number of larval moults, later.
