NEUEOPTEEA ODONATA CHRYSOPA EXTERNA. 921 



CHEYSOPA EXPLOEATA, Hageu. 

 Chrysopa explorata, HAGEN, Syn., 217, 18. 



Collected in New Mexico by Dr. 0. Loew in 1874. 

 HAB. Mexico and New Mexico. 



CHRYSOPA EXTERNA, Hagen. 

 Chrysopa externa, HAGEN, Syn., 221, 32. Ib., U. S. Geol. Surv. Terr., 1873, 599. 



Some specimens in very bad condition collected in New Mexico by Dr. 

 0. Loew. 



HAB. Washington Territory, New Mexico, Mexico, California. 



CORYDALIS. 



One larva of this genus from the Colorado Chiquito, collected in 1873 

 by H. W. Henshaw. 



The larva differs from those of C. cornuta by a larger prothorax, luteous 

 legs, and the mark of the head. There are now six species known from 

 Texas and New Mexico; of course, it is still impossible to ascertain the spe- 

 cies of the larva from Colorado, but probably it may belong to one of the 

 three Texan species (U. S. Geol. Surv. Terr., 1873, 579, 600). 



NOTE. This specimen was inadvertently attributed to Professor Hay- 

 den's collection in the work quoted above. 



RAPHIDIA. 



The genus Eapliidia belongs to the interesting class of genera which 

 are represented largely in Europe and Asia, are entirely wanting in the 

 fauna of North America east of the Rocky Mountains, but are represented 

 again in California and in the other vast tracts of land west of the Rocky 

 Mountains. I have seen only two specimens, one from Ogden, Utah (C. 

 Thomas), the other from Rio Grande, Colorado, June 13 (collected by this 

 expedition). Both belong to different species, and to EapTiidia proper (not 

 to Inocellia). Both being preserved in alcohol, I am not able to give any 

 better information, the more so as the genus EapMdia contains the most 

 difficult species for determination (U. S. Geol. Surv. Terr., 1873, 600).
