ILth. Las Vegas. New Mexico, (ilOO ft. alt., under rocks with Ldgiuti

 larger insect than A*. iiKiritiiini, but closely allied. 



Ripersiella kelloggi Elirhorn i'^ Ckll., sp. n. 



This species was found by Mr. Ehrliorn 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 antenna! joint is about :')(>//. T!ie moutli 

 parts are ordinary, t!ie labium not elongated. 



Ceroputo Su!c. 



Tlie genus Vcropnio, Sulc. was founded in 1897 for a species found in 

 Boliemia, named ('. pUottdbv, Sulc. It lias never l^een recognized as 

 American, but after a study of its cliaraclers, I find tliat tlie species of 

 the group of Phendcorcus yucnc are certainly congeneric. Tlie genus is 

 a fairly distinct one by tlie large size and spiny skin, witli a frequent 

 development of waxy !amel!;e resembling those of Orthezia. Tlie Amer- 

 ican forms are Ceraputo ijikuuc {Pxendorofciix yucca\ Coquillett, W. Am. 

 Sci., 1890, p. 44), ('. iiiicra' mcricdii lis {Ddrtylopius )ne,vir(iniis, Civ!!., Ann.

In C. bdvberi the last tliree antenna! joints are decidedly longer tlian 

 in C. yucca'. To tlie al)ove must now be added t!ie following; 



Ceroputo lasiorum sp. n. 



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

 tinge, covered witli wliite secretion. The dense secretion covering t!ie 

 dorsum loolvs lilce m'oo!, instead of having a chalky appearance as in C. 

 ralcitertus; it is also not separable info distinct lamellae, nor are the 

 hindmost lamelhe at- all prolonged (in calritectus they form two tails); 

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

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

 the 5 turns pink, but does not stain the liquid.
