PSYCHE.

The collection of the Mallophaga is 

 the first made from birds of the Gala- 

 pagos Islands. Specimens of bird-lice 

 were taken from 183 bird individuals 

 representing thirty-four out of the sev- 

 enty-nine bird species so far recorded 

 from the Islands. Mallophaga were 

 taken from t\venty-si.x out of the forty- 

 eight bird species and from all of the five 

 bird genera peculiar to the Islands. 

 There is a total of forty-tiiree Mallo- 

 phagous species represented in the col- 

 lection, twenty-five of which I have de- 

 scribed as new. The problem of the 

 occurrence on the Galapagos birds of 

 previously known species of parasites, 

 and the e.xtraordinary distribution of 

 various Mallophagous species on widely 

 dissimilar bird hosts of the islands make 



the study of this unique collection of 

 Mallophaga a most interesting one. 

 Little of value in the way of suggestions 

 as to the affinities of the five bird genera 

 peculiar to the islands, drawn from a 

 study of their parasites, can be got at 

 until a better knowledge of the Mallo- 

 phaga of the birds of the west coast of 

 .South and Central .\merica is had. Up 

 to the present no collections of Mallo- 

 phaga have been studied from the re- 

 gion south of Panama, but such collec- 

 tions are now being made in Bolivia and 

 and Chili, and their examination should 

 offer much of interest in connection with 

 the present Galapagos Island collection. 

 All the specimens here referred to are 

 now in the entomological collections of 

 Stanford Universitv. 



NOTES ON CRYPTICERYA TOWNSENDI CKLL. 



!V I'. D. A. COCKERELL AND GEO. B. KING. 



Cryptictrya towiisendi was described 

 from specimens collected on the Mesca- 

 lero Apache reservation, N. M. At the 

 same time a var. pliicheae was described, 

 from the Mesilla Valley : I am now con- 

 vinced that this is a valid species, and 

 must be called Cry[^ticcrya plucheae. The 

 next find of C. /cniiiise>iJiws.s on Gutier- 

 rezia at Albuquerque, N. M., by the 

 present writer, in Sept., 1897. So far, 

 the species had only occurred sparingly, 

 and on a single species of plant ; but on 

 Aiig. 26, 1900, my wife and I found 

 it in great quantity on Goat Mtn., Raton, 

 N. M.. living on Compositae of five 



dift'erent genera. The food-plants of 

 C. towiisendi at Raton were submitted to 

 Prof. E. L. Greene who determined 

 them as follows : — • Tmvnsendia grandi- 

 flora Nutt., Picradeniaflorilmnda (Gray), 

 Grindelia squarrosa Pursh, Gutierrezia 

 Siirothrae (Y\ixs\\) and Bahia chrysanthem- 

 oides Gray. Specimens collected at Raton 

 Aug. 26, gave birth to young at the end 

 of October. Mr. G. B. King at my re- 

 quest, has kindly made measurements 

 of the antennae and legs, and these, 

 with other observations, are given by him 

 below. IT. D. A. CofkcrfN.]
