The difference in the relative lengths of the third antennal 

 segment, the great difference in the cornicles, and the difference 

 in the lengths of the beaks are sufficient characters in the writer's 

 opinion to warrant a separation of species. 



Aphis ramona new species (Figs. 5, 11, 22, 23.) 



There came to the writer's hands several specimens of a species 

 of Aphis taken by E. O. Essig and S. H. Essig, county horti- 

 cultural inspector of Ventura County, on black sage (Ramona 

 stachyoides, at Nordhoff, Ventura County, August 1911, and at 

 Santa Paula, April 1913. Concerning its habits Essig merely 

 notes, "Attacks black sage, more or less heavily parasitized, at- 

 tended by ants to a large extent." The species does not agree 

 with any known to the writer, nor to Essig or Davis, both of whom 

 examined specimens, consequently it is herewith described 'as a 

 new species, being named Aphis ramona, after the generic name 

 of its only recorded host plant. Cotj^pe specimens are in the 

 private collection of E. O. Essig, in the private collection of the 

 writer, and in the collection of the Universit}^ of California under 

 the serial number EOE 12. The color notes in the following 

 description are taken from those of E. 0. Essig. 



Alale liviparous female. — Prevailing color green and dark-brown, the head 

 being dark-brown, with a distinct tubercle at the apex of the front and small 

 but distinct antennal tubercles (fig. 5). The eyes are red. The antennae 

 (fig. 11) are dusky brown thi-oughout, except the tip of V and all of VI, which 

 are slightly paler. Segment III is the longest segment, the spm- of \T next, 

 followed by IV and V which are subequal, but slightly shorter than the spur of 

 VI and about one-third the length of III. I and II are subequal and about 

 two-thirds the length of the base of VI. The usual primary sensoria are present 

 on V and VI and the accessory on VI. Segment IV has from one to four fairly 

 large, circular, secondary sensoria, placed in a more or less even row along the
