180 THE ENTOMOLOGIST'S RECORD. 



escaped, showing perhaps my negligent care of them, in consequence,,. 

 probably, of which only one finally matured. They did not progress 

 nearly as rapidly as their brethren under maternal care. I considered 

 this to be largely due to the food supplied them, not being in a properly 

 damp nest, was not always so satisfactory as was desirable, and also to 

 the fact that they had to find it, not always so easy as it looked when 

 the larvffi were small. I concluded that the young earwigs could very 

 well find their own living if at large and without maternal care, but 

 would be handicapped as to always finding food when they wanted it, 

 but that probably want of all defence against enemies would be their 

 most serious deficiency if left to themselves. 



It was observed in a particular case in which there were two nests 

 of about the same age in one jar, that the young earwigs, if they 

 wandered from the nests, which they often do in the second and 

 third instars, would, on being disturbed, make for either nest, and 

 were apparently equally welcome though it was not their own. I 

 have, for instance, turned one nest out, and a goodly number would 

 soon find the other where their entry was in no way resented or 

 specially noticed. 



The six curious circles found in both the living earwigs and in the 

 cast skin, and whose nature puzzled me, appear to be the chitinous 

 margins of glandular masses in the intestinal wall, some little way 

 above the anus, and are cast with the intestinal lining at each moult.- 

 In mounting m balsam the rest of the intestinal lining becomes 

 invisible, by other procedure this difficulty was obviated, and an ex- 

 amination of such specimens showed the lining membrane. 



With hardly any preparation the glands in the intestine were seen 

 to be bounded on the intestinal wall by the rings, and to have a 

 thickness rather less than their width, and each is richlj' permeated- 

 by tracheae and tracheoles. The six glands are disposed in two sets of 

 three, one in advance of the other. The anterior set has one gland 

 mid-ventral and two lateral. The posterior set alternate with these, 

 one mid-dorsal and two lateral, but ventral to the forward lateral pair. 

 My experiments on regeneration of antennte, etc., were so far 

 vitiated by confusion with injuries inflicted by the earwigs themselves 

 that I am not satisfied that any of my results are trustworthy. I 

 fancy that the experiments encouraged mutual injuries, but these were 

 most abundant, affecting almost every example in the brood, in the 

 case of one set of larva, where I was quite unable to suggest any cause, 

 except perchance more than usual original sin in that particular 

 sample. 



New Subspecies of Caligo.

Calif/o teucer subsp.70a.srt, J. & K. 



Forewing as in typical teucer, except that the slaty-greenish area 

 between veins 1 and 2 in the basal area is paler and the transverse 

 yellow band more pronounced. Hindwing with the whole of the basal 

 half of the wing brilliant shot peacock blue. Marginal half deep black 

 with very pronounced white fringe from vein 7 to vein 2. 



Habitat. — Upper Amazon, San Joas, Solimces. 



Type in coll. Joicey.
