county, state or country, altitude if not readily and exactly as- 

 certainable from a geographical hand-book, date including year 

 (and the month should never be indicated by Arabic numerals, 

 for an American abbreviates October 9, by 10-9, and an Eng- 

 lishmen, 9-10, not that these are unfailing national characters), 

 and the name of the collector as a clue to the specimen's his- 

 tory. 



Some insects will require additional information, as to the 

 plant or the nature of the soil, or the species of animal on which 

 they were taken. 



No specimen intended for preservation should be ticketed 

 with a number only and all the information separately recorded 

 under that number in a book. The chances are in favor of 

 book and specimen following different paths in the maze of 

 life whereby the specimen soon passes into the limbo of forgot- 

 ten things.

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



MOSQUITOES FED BY ANTS. The Javanese ant, Cremastogasler diffor- 

 mis Smith, excavates its nests in ends of dead branches. When these 

 nests are placed in unfavorable places they become filled with rain- 

 water, and are abandoned by the ants. In this water the mosquito, 

 Harpagomyia splendens de Meijere, lays its eggs, and is not known 

 to occur elsewhere than in association with this Cremastogaster. 

 Breeding the ants and the mosquitoes together, E. Jacobson found that 

 the mosquitoes spent much time on an upright rod supporting the ants' 

 nests, rocking their bodies gently to and fro, until an ant ran along 

 the rod between a mosquito's legs. The ant was then caressed and 

 produced a drop of liquid between its wide-opened jaws, which was 

 sucked up by the probosis of the mosquito. The operation is figured 

 by some photographs and drawings on three plates (Tijdschrift voor 

 Entomologie. liv, pp. 158-161, taf. 11-13, 1911). In a description of 

 the larva and pupa of this Culicid, following Jacobson's paper, Prof, 

 de Meijere points out, as of special interest, that, although the adult 

 Harpagomyia possesses neither mandibles nor maxillae, rudiments of 

 these mouth parts are present in the pupa.
