TABULATION OP TttE SUB-GENEItA INCLtJDED IN APATELA, ETC. 295 



B. Genus: Cmniophora, Snell. (1872) = Bisulcia, Chapn. 



(1893).— Type : C. WjicUri. 

 1.— C lu/ustri, Linn. 

 This genus appears to me to be valid on structural characters, and 

 this name acceptable as a proper restriction of Pnli/mLvis, Hb. (1818), 

 which latter has then as type : Pohpmta, Ltinn., " Syst. Phal.," 180. 

 Sel(ul<niia, Fabr., " Ent. Noc," 188. Ridem, Hb., "Noc," 20, 

 vi(h' the Verzcichui^s, 205 ; but I have not been able to come to a final 

 conclusion, and it is possible that the type poh/mita is untenable, Avhen 

 the present genus will have to be called Pohpuixi)^. But from the 

 larva the genus must be referred to the Ai/rotidac, the set^e being 

 single and tubercles not being converted into many-haired warts ; 

 HetcnnnorpJia raendeorephala, usually referred here, must also be 

 removed from the ApateUdae. The generic characters of ligustri are 

 the retreating inner edge of primaries, the mixture of flattened scales 

 on the thorax, and the peculiar arrangement of the vestiture, together 

 with the dorsal tufts on abdomen. The character of the vestiture 

 seems to ally the moth to the North American genus, Cfvjtonix. 



Larval Genera and Sub=genera in Apatela. 



By A. RADCLIFFE GROTE, M.A. 



The following classification of the adult larvae of Apatda is drawn 

 up from memoranda furnished by Dr. Dyar, and verified by me, so far 

 as my material allows ; (E) stands for the European, (A) for the 

 American species. Where no name follows the section no name has 

 been proposed. As a rule, I consider such naming unnecessary, and 

 that the species may be associated under the preceding sub-generic 

 title. 



Gen. \.— Apatda, Hiibn., 1806 (1811). Type: A. accris. 



Secondary hairs abundant, tending to obscure the warts. [The 

 larva of Irjmrina has black hair pencils in young stage on first and 

 third abdominal ("long black hairs on the anterior trapezoidals," 

 Chapman), as the North American vul})ina, and on the same segments as 

 amcricana. No larva has been yet found in America which can be 

 classed in the same section with aceris. Mr. Tutt's statement, Ent. 

 Rec, vii., 59, that ainrricana is " really congeneric with aceris " is, in 

 any close sense, inaccurate] . 



1. No black pencils or tufts : 



a. Hairs parted into interlacing pencils : aceris {K) = Apatda. 



b. Hairs fluffy ; black pencils in young : Icporina (E), 



rulpina {A) = Acrnnicta. 



2. With black dorsal pencils on definite segments : amcricana 



(A), dacti/liiia (A), lepmcidina (pnpuli) (A), fdina (A), 

 an undetermined species {A) — Me(/acrnu>/cta. 

 Gen. II. — Hi/bnwa, Hiibn., 1818. — Type: 7/. strii/osa. 

 Hairs all weak, Avarts reduced in size, secondary hairs often nearly 

 wanting, and warts sometimes single haired. 



1. Hairs not single on dorsal warts (i.-iv.) : 

 § Not green at maturity : 



a. Fleshy humps on segments 5, 12 : psi (E), tridens (E) 

 = Triaena.
