LEPIDOSAPHES versus MYTILASPIS. 



BY MRS. C. H. FERNALD, AMHERST, MASS. 



The genus Lepidosaphes was established by Dr. Shinier, in the 

 Transactions of the American Entomological Society, Vol. I., p. 372, 

 Jan., 1868, with one species (conchiforjnis =u/iHi, Linn., 1758). 

 Although the generic description is not all that could be desired, 

 it is certainly more satisfactory than the descriptions of many genera of 

 insects in this and other orders which have been accepted without 

 question. 



The generic name Mytilaspis was first pubhshed, without a word of 

 description, by Signoret, in his Catalogue of the Coccida^ in the Annales 

 de la Societe Entomologique de France (4), Vol. VIII., p. 841 (1868). 

 This paper was presented to the Society at the Seance of March 25th, 

 but was not published till later in the year. A description of this genus 

 was given by Signoret in the above-named work for 1S70, page 91. This 

 article was presented to the Society at the same time as the catalogue. 



The genus Mytilaspis was evidently first proposed by Targioni- 

 Tozzetti, in his Coccidarum Catalogus, which was published in the 

 Atti della Societa Italiana di Scienze Naturali, Vol. XL, the title page of 

 which bears the date of 1S68, but the volume was published in four parts, 

 and the paper covers of these parts bear the following dates : Part L, 

 June, 1868; Part II., October, 1868; Part III., February, 1869; Part 

 IV., April, 1869. Targioni's Introduzione alia seconda Memoria per gli 

 studj sulle Cocciniglie and his Coccidarum Catalogus were both published 

 in the third part of this work, and these papers should therefore date from 

 1869 rather than from 186S, the date usually given them. 



In his Cocciniglie degU Agrumi in Italia, p. 22 (1891), Targioni gives 

 the characters of Mytilaspis, and refers to his Studi sulle Cocciniglie 

 (1867) and also to the above-named works. The name Mytilaspis, 

 however, does not occur in his Studi, and therefore was not published by 

 Targioni earlier than February, 1869. 



Signoret speaks of having received Targioni's Catalogue in Ann. Soc. 

 Ent. Fr. (4), Vol. IX., p. 113 (1869), but as it was not published at that 

 time, we must conclude that he received a manuscript copy. 



Under the circumstances it seems proper to use the generic name 

 Lepidosaphes as Kirkaldy has done in his late paper on the Coccidiv> in 

 Fauna Hawaiiensis, although, of course, we are sorry to give up the 

 familiar name Mytilaspis,
