Hub. Las Vegas, New Mexico, 6400 ft. alt., under rocks with Lasius 

 americarws; first found by Wilmatte P. Oockerell, April 11, 1901. A 

 larger insect than It. Mfiritiina, but closely allied. 



Ripersiella kelloggi Ehrhorn *fc Gkll., sp. n. 



This species was found by Mr. Ehrhorn on roots of bunch grass at 

 Mountain View, California, in December, 1898, but no description has 

 yet been published. It is easily recognized by the characters mentioned 

 above. The length of the last antennal joint is about 30 /i. The mouth 

 parts are ordinary, the labium not elongated. 



Ceroputo Sulc. 



The genus Ceroputo, Sulc. was founded in 1897 for a species found in 

 Bohemia, named (J. pilosclke, Sulc. It has never been recognized as 

 American, but after a study of its characters, I find that the species of 

 the group of Pheudcoccus yucca- are certainly congeneric. The genus is 

 a fairly distinct one by the large size and spiny skin, with a frequent 

 development of waxy lamellae resembling those of Orthezia. The Amer 

 ican forms are Ceroputo yucca- (Peitdococcu yucca*, Coquillett, W. Am. 

 Sci., 1890, p. 44), (J. yucca' mtxicanu* (Dactylopius mexicanvs, Ckll., Ann. 

 Mag. Nat. Hist., ((5) XII, p. 49), C. larberi (Plienacoccu* yucca barleri; 

 Ckll., Ann. Mag. Nat. Hist., (6) XVI, p. 61), V. bakur (Phcnacocruit bahia>, 

 Ehrhorn, Can. Ent., 1900, p. 314), and C. calcitectus (Phenacoccux culci- 

 tectun, Ckll., Ann. Mag. Nat. Hist., (7) VII, p. 334). 



In C. barberiihe last three antennal joints are decidedly longer than 

 in C. yucav. To the above must now be added the following: 



Ceroputo lasiorum sp. n. 



9 . About 4 mm. long, 2 broad, almost white, with a faint greenish 

 tinge, covered with white secretion. The dense secretion covering the 

 dorsum looks like wool, instead of having a chalky appearance as in C. 

 calcitectus; it is also not separable into distinct lamella?, nor are the 

 hindmost lamellae at all prolonged (in calcitectus they form two tails); 

 in young individuals the lateral tufts are distinct. Legs pale reddish- 

 brown; sepia brown in mounted specimens. Boiled in liquor potassce, 

 the ? turns pink, but does not stain the liquid,
