SCENOPINIDAE OF THE WORLD 215 



146. Metatrichia bulbosa (Osten Sacken) 



Figure 140 

 Scenopinus bulbosus Osten Sacken, 1877, p. 275. 



This is the most widespread North American species in the family 

 Scenopinidae. 



It is a robust species covered with flat scale-Hke hairs. 



Length: Male body 4-4.5 mm., wing 3-3.3 mm.; female body 

 3.5-5.3 mm., wing 3.2-4 mm. 



Type-locality: Missouri, in July (C. V. Riley). 



Type: (MCZ) 1057. 



I have examined specimens from the following localities : California ; 

 Isla San Jose and Pulpito (anchorage), Gulf of California, Mexico; 

 Texas; New Mexico; Washington; Idaho; Nevada; Kansas; Nebraska 

 (Scotts Bluff); Illinois; South Carolina; District of Columbia (Wash- 

 ington) ; Virginia (Mt. Vernon) ; West Virginia (Lost River State 

 Park) ; Pennsylvania; New Jersey; New York (Babylon, Long Island) ; 

 Connecticut; Massachusetts (Hollister) ; Vermont (Rupert Mt.) ; 

 and Delaware. One specimen from Nogales, Arizona, was taken 

 from a tunnel in a rose cane. No other clues as to their habits or 

 habitat are known. 



147. Metatrichia lophrysoma (Speiser), new combination 



Figure 141 

 Pseudomphrale lophrysoma Speiser, 1920, p. 216. 



The type of this species is presumed lost; a search of the material 

 from the Stettin Collection now housed in (PAS) failed to produce 

 it. However, two specimens exist in (AMNH) from the Belgian 

 Congo which agree closely with Speiser's description and have been 

 illustrated. This is the largest of all the Scenopinids examined by me. 



Length: Female body 7-7.5 mm., wing 5.5 mm. 



Type-locality: Willowmore, [Republic of] South Africa; November 

 1907 (H. Brauns). 



Type: deposited in Stettiner Museum (lost). 



Specimens seen: 299, Banana, Belgian Congo, 6° S. 12°20' E.; 

 July 1915 (Lang and Chapin) (AMNH). 



148. Metatrichia robusta Krober 



Figure 142 



Metatrichia robusta Krober, 1913, p. 180. 



The type of this species has been lost but I was fortunate to find a 

 number of specimens of both the male and female for figuring and 

 description. The female has not previously been described.
