MISCELLANEOUS NOTES. 



Tibicen inauditus. — This cicada was described and figured in the 

 Journal of the N. Y. Entomological Society for December, 1917, 

 from the type and two other males collected west of Vega, Oldham 

 County, Texas, July 15, 1917. Miss Mildred McGill has sent me a 

 fourth male collected in the same county at Tascosa, Texas, June 25, 

 1918.— W. T. Davis. 



Dorcasta obtusa. — This beetle is described by Henry W. Bates in 

 Biologia Centrali-Americana, Coleoptera, V, p. 372, from Cerro de 

 Plumas, Mexico (Hoge), and Mirandilla, Guatemala (Champion). 

 The insect is figured on Tab. 23 (Coleoptera), fig. 1. On May I', 

 1912, the writer collected a single example of this species at South 

 Bay, Lake Okeechobee, Florida, which appears to be the first speci- 

 men known from the United States, and, according to Mr. Leng's 

 recollection of an unnamed specimen in the Gundlach collection in 

 Havana, occurs also in Cuba. In Mexico, Central America, and 

 South America there are a number of other species belonging to the 

 genus. — Wm. T. Davis. 



The Males of the Roach, Pycnoscelus surinamensis. — In his excel- 

 lent paper on the Blattidse of North America Mr. Morgan Hebard 

 has this to say concerning desirable field work and the Surinam cock- 

 roach as found in North America : " To find if this insect is parthe- 

 nogenetic in America ; nearly four hundred females have been re- 

 corded from this continent, but no males." On page 196 he states 

 further: " In addition to the large series from the United States, we 

 have examined nearly two hundred specimens of this species, chiefly 

 from the West Indies and Mexico, without finding a single male, 

 adult or immature, from the American continent." He further quotes 

 from Brunner, who had males from the East Indies, but " states that 

 not a single male was present in his series of over forty specimens 

 from tropical America."
