 Kermes Austifii, n. sp. 



$ scale spherical, about 4.5 mm. broad, 4 mm. long, 4 mm. high. 

 (Amongst the material are a number of parasitized specimens, which are 

 much smaller in size.) Dorsum slightly covered with a waxy secretion. 

 Scale not gibbous and segmentation indistinct, indicated by brown dots 

 when seen through a lens. Colour light brown, with several irregular 

 white stripes running parallel with the segments. There is a distinct 

 groove on the caudal portion of the scale, which is distinctly marked with 

 brovvn. Scale more or less pitted. Pits generally marked dark brown or 

 black. Ventral scale is more or less flat and light brown. Keel not 

 very prominent. When boiled in K. H. O. derm is light brown, with 

 several brovvn spots and numerous round glands — orifices, which are 

 larger near the margin. A few short spines near the margin. Antennte very 

 short and stout, indistinctly 6-jointed. Joint 3 longest, 4 and 5 subequal. 



Larva (taken from body of $ ).— Colour pink, twice as long as 

 broad. After boiling in potash, colourless. Antennte and legs yellow. 

 Antennae 6-jointed. Joint 3 longest, then comes 6 with numerous 

 stout bristles and rounded at tip. Joints 2 and 5 subequal. Joints i 

 and 4 about equal. Formula : 36(25)(4i). Caudal tubercles large, with 

 very long setse and three stout spines — one at base of tubercle, one on 

 its inner margin, and one near setae. On the margin of body each 

 segment has a stout spine. Legs stout. Tarsus not twice as long as 

 tibia. Femur nearly as long as tarsus + tibia. Claw slender and curved. 



Hab. — On twigs of Querciis oblongi/olius, Guejito Mountains, eight 

 miles east of Escondido, San Diego Co., Cal. (F. Austin, coll.) 



This species is allied to Kermes gallifonnis, but smaller, with the 

 darker parts of a decided fulvous colour. Prof. Cockerell has examined 

 specimens, and agrees that it appears to be a valid species. 



Lecaniodiaspis rufescens, Ckll. 



This species was sent to me from Los Angeles, Cal. Found on a 

 new food plant, Adenostotnafascicu/attun,
