PSrCHE. 



[February 1898. 



bend inward over the back, the spines 

 becoming converged and the whole con- 

 cealed by a triangular fold of skin. The 

 presence of this fold is the only essential 

 difference between these tufts of Dorati- 

 fera and our Parasa. The muscular 

 function may be slightly present in 

 Parasa ; it is certainly so in Sisyrosea 

 nasoni, though in this case the horns 

 bend outward. 



The second modification is produced 

 by the lengthening of the horn and the 

 reduction of the stinging spines. I find 

 on the tentacles of the larva sent me by 

 Mr. Olive not only a few setae, but 

 several distinctly formed, though very 

 short stinging spines, as well as a great 

 number of degenerate irregular lumps, 

 representing the mass of the spines. In 



this larva the tentacles are present for 

 all the horns of the lateral row and joint 

 13 as well as for the subdorsals of 3 and 

 12 where they are especially long. 



The subdorsals of 6 to 11 are very 

 short, rudimentary, again much as in 

 our Pai-asa, but their spines are absent, 

 just as on the long horns, which is not 

 the case in our species. 



To summarize: the Australian Eu- 

 cleids belong to the group of the horned 

 Eucleids of Asia, Africa ( ?)* and Amer- 

 ica, but difler in having the spines 

 removed from the horns which have 

 not become eversible. It is a distinct 

 and peculiar specialization of one of the 

 highest types of larvae and possibly 

 I'epresents the most modified Eucleid 

 larva on the earth. 



PACIFIC COAST COLLECTING. — II. 



BY ALBERT PITTS MORSE, WELI.ESLEY, MASS. 



LOCALITIES. 



Yuma_ R. R. hotel; drinking- 

 water detestable. Surroundings chiefly 

 river-flats covered with willow-thickets, 

 and desert. A rocky hill, chaparral, 

 and ranches at a little distance. This 

 place and points in Colorado Desert are 

 likely to be extremely hot. 



India. R. R. hotel. Desert thickly 

 covered with weeds and chaparral ; 

 fruit ranch with artesian well and run- 

 ning water. Mesa and foot of moun- 

 tains 3 to 4 miles distant. A good 

 place, 



Palm Springs. Five miles from 

 station of same name and directly at 

 base of San Jacinto Peak. Inn and 

 fruit ranches. Desert, ranches with 

 fields and orchards, several canyons 

 with wild date-palms, streams, water- 

 falls, etc. An extremely favorable 

 locality. 



Additional places in the Colorado 

 Desert that would probably repay 

 visits are Flowing Well — natural 

 spring, — Salton — 250 ft. below sea-
