TWO NOTES ON TINEID MOTHS.

Description of the Larva of Ethmia longimaculella Cham- 

 bers. — This larva was received at the National Museum from Dr. 

 James Fletcher, Ottawa, Canada, with a memorandum stating that it 

 was bred on Lithosperma officinale. 



La'va. Head rounded, bilobed, flattened before, rather thick, dull black 

 throughout, the seta; coarse and pale ; width 2 mm. Body cylindrical, uniform, 

 rather stout, feet normal, skin smooth. General color purplish black with a few 

 transverse white bands. Cervical shield large, bright orange colored, bisected by a 

 yellowish line, tubercles concolorous. Neck white ; sides of joint 2 behind the spi- 

 racle white ; white bands in the intersegments of joints 3-4, 4-5, 9-10 and lo-ii, 

 the two anterior ones rather narrow dorsally, strongly widened below the spiracle, 

 the two posterior nearly uniform in width, none passing to the venter. Tubercles 

 small, black, normal, iv and v united, vii with a dark plate bearing numerous seise. 

 Feet all ringed with black. ^'^"''^''^^ '^'"'"(j'-^oP '\Ji£h 



A Case of Synonymy. — My colleague, Mr. August Busck, de- 

 scribed a new genus and species of Tineids as Dorata virgatella (Proc. 

 Ent. Soc. Wash., VI, 123, 1904), from Arizona, placing the genus 

 in the CEcophoridse. Having occasion to look over Lord Walsing- 

 ham's description of Pterolonche Uneata (Insect Life, I, 284, 1889), 

 I was at once struck by the similarity to Mr. Busck' s species, and a 

 comparison convinces me that they are the same. The very peculiar 

 $ genitalia of vii-gatella agree well with Lord Walsingham's descrip- 

 tion of those oi Uneata. Lord Walsingham placed the species in Zel- 

 ler's genus Pterolonche in the Yponomeutidse. Unfortunately I have 

 no specimens of this genus, but it appears not improbable that Mr. 

 Busck' s genus Dorata will prove a good one. Unless the contrary be 

 shown when specimens are at hand, the forms will be listed thus : 



Dorata Busck. 



lineata Walsingham. 



vii-gatclIa Busck. 

 inornatella Busck. 



The genus falls in the CEcophoridas rather than the Yponomeutid?e 

 by Meyrick's tables, as Mr. Busck states.
