252 Miscellaneous. 



digitiform processes are found, the longest of which are about as 

 long as twice the diameter of the proboscis at this point ; the re- 

 maining third gradually contracts, and is thickly studded with half- 

 rings of small papillae, which seem to mark indistinctly the seg- 

 ments of the organ. Total length of the proboscis, when extended, 

 about three times that of the claspers. Total length 12-14 millims. 

 Habitat, "Woodbury, New Jersey. 



I name the above species in honour of Mr. D. S. Holman, actuary 

 of the Franklin Institute, in recognition of the services he has ren- 

 dered in devising methods for stud)'ing living objects, both large 

 and small, under the microscope, and to whom I am also indebted 

 for the specimens from which the above description has been taken. 



The detection of a member of the genus in this country is very 

 interesting, but less so than the detection of Pauropus Huocleyi, Lub- 

 bock, in the vicinity of Philadelphia, without any difference, as far 

 as Sir John Lubbock's excellent plates of English specimens would 

 enable one to judge, that would make it even a variety, although re- 

 moved by more than 3000 miles of ocean from its congeners. It 

 has been suggested, however, that, inasmuch as Philadelphia is an 

 old English settlement, Pauropus may have been introduced ; but 

 in. the case of Chirocephahis such an explanation is less open to 

 acceptance. — Proc. Acad. Nat. Sci. Philad., April 29, 1879. 



Note on the Adoption of an Ant-Queen. 



Mr. McCook reported the following case of the adoption of a fer- 

 tile queen of Crematoyaster lineolata, a small black ant, by a colony 

 of the same species. The queen was taken in Eairmount Park, 

 April 16, and on May 14 following was introduced to workers of a 

 nest taken the same day. The queen was alone within an artificial 

 glass formicary; and several workers were introduced. One of these 

 soon found the queen, exhibited much excitement, but no hostility, 

 and immediately ran to her sister workers, all of whom were pre- 

 sently clustered upon the queen. As other workers were gradually 

 introduced they joined their comrades until the body of the queen 

 (who is much larger than the workers) was nearly covered, with 

 them. They appeared to be holding on by their mandibles to the 

 delicate hairs upon the female's body, and continually moved their 

 antennae caressingly. This sort of attention continued until the 

 queen, escorted by workers, disappeared in one of the galleries. 

 She was entirely adopted, and thereafter was often seen moving 

 freely, or attended by guards, about the nest, at times engaged in 

 attending the larva? and nymphs which had been introduced with 

 the workers of the strange colony. The workers were fresh from 

 their own natural home ; and the queen had been in an artificial 

 home for a month. As among ants the workers of different nests 

 are usually hostile to each other, this adoption of an alien queen is 

 an example of the strong instinct which controls for preservation of 

 the species. — Proc. Acad. Nat. Sci. Philad., April 1, 1879.
