252 PROCEEDINGS OF THE ACADEMY OF [July, 



We wish to express our cordial thanks to the curators of the 

 collections of the Museum of Comparative Zoology, United States 

 National Museum, American Museum of Natural History, and Field 

 Museum of Natural History for the loan of material. We are 

 particularly indebted to Dr. Samuel Henshaw, of the Museum of 

 Comparative Zoology, for permitting us to have for comparison and 

 study the types from the Scudder Collection, without which we would 

 have been unable to undertake the present work. 



Netrosoma fusiforme Scudder. 



1897. Aetrosoma fusiformis Scudder, Proc. U. S. Nat. Mus., XX, p. 17, 



PI. II, fig. 2. [Monclova {nee Montelovez-), Coahuila {nee Chihuahua'), 



Mexico.] 

 1908. Netrosoma fusiforme Brunei-, Biol. Cent.-Amer., Orth., II, p. 300. 



(Same material.) 

 19i0. N[etroso7na\ uniformis Kirby, Syn. Cat. Orth., Ill, p. 486. (Lapsus 



calami.) 

 Monclova, Coahuila, XI, 23, 1909, (F. C. Bishopp), Ic^, 2 9 , [U. S. N. M.]. 



These strikingly beautiful examples are in no way different from 

 paratypes now before us. 



Netrosoma nigropleura Scudder. 



1897. Netrosoma nigropleura Scudder, Proc. U. S. Nat. Mus., XX, p. 18, 



PL II, fig. 3. [Lerdo, Durango, Mexico.] 

 1908. Netrosoma nigropleurum Bruner, Biol. Cent.-Amer., Orth., II, p. 300. 



(Same material.) 

 Jaral, Coahuila, XI, 1 to 3, 1909, (J. Friesser), 1 9 , [Field Mus. Nat. Hist.]. 



The size contrast between the sexes of the present species is even 

 greater than in N. fusiforme. The female is also very different from 

 the male type, in the Hebard Collection, in being almost solid rood's 

 brown in general coloration, the two darker bands of the caudal 

 femora being only very faintly indicated dorsad. As in the male, 

 the caudal tibiae are pompeian red, this weaker externally proximad. 

 The measurements of this female are as follows; length of body 20.8, 

 length of pronotum 4.7, greatest (caudal) width of pronotum 6.1, 

 length of caudal femur 11.6, width of caudal femur 3.5 mm. In the 

 male type the length of the caudal femur is 8.8, its width 2.8 mm. 



DichroplUS notatUS Bruner. 



1908. Dichroplus notntus Bruner, Biol. Cent.-Amer., Orth., II, p. 301. 



[cf , 9 ; Arnula, Guerrero, Mexico, 6000 feet.] 

 Cuernavaca, Morelos, 1905, (VV. L. Tower), 1 9, [Tower Cln.]. 



This specimen is slightly larger than a cotypic female in the 

 Hebard Collection, being 19.7 mm. in length, and is more richly 



- This error appears repeatedly in Scudder's revision, due to the incorrect entry 

 of Palmer's assorting number 1221 in the book used by Scudder. 



^ Scudder in some places gives Chihuahua incorrectly as the State, in other 

 places he is more nearly correct, giving "Cohahuila. "
