SUBFAMILY APHINAE 19 
Apterous Summer Vivipara. Dark olive-green to slaty-brown; thickly covered with 
flocculent secretion; appendages dusky with black tips. Body 2-2.5; hind tibia 1.3-1.8; an- 
tenna 1.1-1.2. Appendages siender; diameter of antennal III -03-.04, of hind tibia, .065, of 
hind tarsal II .03. 
Alate Vivipara. Same in color and measurements as apterous vivipara. 
Rostrum obtuse, attaining between 2d and 3d coxae. Hairs on hind tibia over three times 
as long as diameter of tibia; on antenna as long as three times diameter of III. Secondary 
sensoria on antenna round. Fore wing with media usually twice-forked but occasionally 
simple. 
Ovipara. Apterous. Body length 2.3-2.7; antenna 1.3; hind tibia slightly swollen on 
proximal half and bearing scattered sensoria. Otherwise as in apterous vivipara. 
Male. Alate. Almost black; covered with heavy flocculence; appendages, costal margin 
and stigma of fore wing black. Body length 2; antenna 1.50-1.57; hind tibia 1.60. Otherwise 
as in alate vivipara.

Fig. 13. Schizolachnus pini-radiatae 
Collections. On needles of Pinus ponderosa var. scopulorum and P. con- 
torta var. murrayana. Throughout region. Fundatrices April 7 to May 22, 
apterous viviparae May 28 to Oct. 2, alate viviparae May 28 to July 18, oviparae 
Sept. 27 to Nov. 25, males Sept. 27 to Oct. 23; common. 
Type. Possibly U.S.N.M. 
This form differs slightly from metatype specimens taken on Pinus radiata 
as follows: Slightly longer and stronger hairs and more numerous sensoria 
(3-8) on III in alate vivipara of the California examples. These differences do 
not seem sufficiently distinct, considering the small number of alate specimens 
at present available, to justify the erection of a separate species. 
Subtribe Cinarina Borner 
Borner, 1930:125. 
Characters. Usually large hairy forms, brown or greenish to black, often 
with pattern of white secretion. Cornicle usually on hairy cone. Rostrum 
lancelike, segment V distinct. Hind tarsal I trapezoidal in lateral aspect, 
dorsal side fully half as long as ventral side. Fore wing with stigma elongate 
and radial sector straight reaching almost to tip of wing. Ocular tubercle 
usually evident. Action usually rather quick and spiderlike. Living free on 
Coniferae, on needles and bark of limbs and twigs. 
Only one’genus represented in region.
