Habitat: Ray, Ariz., 4400 feet altitude, H. S. Barber, collector 



Foodplant: Agave palmeri. 



Type: Cat. No. 19290, U. S. N. M. 



I am pleased to dedicate this interesting and pretty species 

 to Mr. Barber who, on January 4, 1914, cut a tall dry flower 

 stalk of the Agave in Arizona and brought it to Washington, where 

 more than a hundred moths issued from it about the middle of 

 March. The Iarva3 are glassy white with light brown head and 

 dark brown mouth parts; they are, as is tyoical of the genus, en- 

 tirely apodal, without any trace of thora* legs or abdominal 

 prolegs; length 12-14 mm.; before pupation .ley bore out to the 

 surface of the stalk, leaving only a thin silk lined circular lid, 

 which is pushed out by the pupa at emergence; the pupal shell 

 is thin and flimsy and remains protruding from the exit hole. 



The genus Prodoxus Riley has been incorrectly sunk as a syn- 

 onym of Tegeticula Zeller ( == Pronuba Riley) in the Biologia. The 

 two genera are abundantly distinct in all stages; the larva of 

 Tegeticula has thoracic legs, that of Prodoxus is apodal; the pupa 

 of the former is strongly and characteristically spined, while that 

 of Prodoxus is smooth, and the remarkably developed "Maxillary 

 tentacle" in Tegeticula is represented in Prodoxus only by a 

 slight protuberance. 



RHABDOBLATTA BRUNNEONIGRA, A NEW COCKROACH FROM 



CHINA. 



BY A. N. CAUDELL, Bureau of Entomology. 



Among a few miscellaneous Orthoptera from China recently 

 received for determination from N. Gist Gee of Soochow was 

 a large roach which, according to Shelford's keys, belongs to the 

 genus Rhabdoblatta. The species is apparently a new one and 

 the following description is therefore presented. 



Rhabdoblatta brunneonigra n. sp. 



A brownish black roach nearly one and one-half inches in length ex- 

 hibiting the following characters : Head projecting somewhat from beneath 

 the pronotum; eyes large and separated by a distance as great as twice the 

 greatest width of the basal segment of the antenna?; ocelli large and as 

 widely separated as the eyes; antenna; shorter than the body, the basal 

 segment large and over twice as long as broad, the second slightly smaller 

 and scarcely longer than broad, the succeeding ones gradually diminishing 

 in diameter, those of the basal third or so transverse, beyond growing more 

 elongate, those towards the apex slightly more than twice as long as broad. 

 Pronotum about twice as broad as the head, the widest part slightly in 

 advance of the middle, anteriorly very broadly rounded and posteriorly 

 obtuse angulate, the disk with a pair of somewhat obscure shallow de- 

 pressions on each side of the middle. Legs moderately stout, all the
