described by Fallen under tliis name, and accepted by Tliomson 

 (Opusc. Ent., iv, 418, 1). Ph. uJmi, D. and S., I. c, is, on the contrary, 

 very scarce in Sweden, and lives specially on dry hills, among CaUuna 

 and Galium, and on brambles, etc. ; it seems to me, therefore, not 

 correct to name it Ph. ulmi, but it must be called Ph. varipes, Boh. 

 (Ent. ant. sodra Sverige, p. 107).

APTEROUS MALES IN THE COCCIDM. 



BY JULES LICHTENSTEIN (of Montpellier). 



Dr. Le Baron, in his First Report for the State of Illinois in 

 America, page 88, says : 



" Nature, in the universality of her providence, takes them (the 

 motionless female Cocci) in her charge, and ministers to their 

 necessities, and no unloved or unfruitful virgin is permitted to 

 languish in the halls of the Coccidce.'''' 



This was said of the Pine-leaf scale-louse, and E-iley, in the Insects 

 of Missouri, Fifth Eeport, 1873, p. 73, gives also a very full and 

 interesting account of another Scale-louse, ^^ Mytilaspis pomicorticis,'' 

 in which the natural history and complete biology of the aerian 

 Coccidce are well elucidated. Since then. Prof. Signoret in his mono- 

 graph has described a quantity of males, among which I. had the good 

 luck of finding some new ones, but all winged. 



Now there is a very common large Coccidian (noxious in our 

 country), which lives underground, sucking the roots of grain-plants, 

 such as Avena, Triticnm, Hordeum, &c., kno^Yn long ago, and it most 

 likely is that already described (if it can be called a description) by Fa- 

 bricius, under the name Coccus phalaridis, which " habitat ad qraminium 

 radices;'' and after that it was more accurately examined by Boyer 

 de Fonscolombe (Ann. Soc. Ent. Fr., 1834); Barensprung, Journ. Zool. 

 and Palseont. 1848 ; Targioni Tozzetti, 1867 ; and Signoret, 1874 ; 

 although the last seems not to have had in view the same species, but 

 an allied one (Aclerda). 



Of course the females only are noticed by all these authors, as 

 " a large mealy-bug, exuding a white cotton-hke secretion, which 

 forms a bag around and behind in whicli the eggs are deposited." 



It is rather a large insect for the family to which it belongs ; its 

 length is about G millimetres by 21 to 3 wide, of an oval form, with 

 6-iointed antennte and well-formed legs, tohich the animal preserves 

 until death.
