hind tibia 1.53-1.75-‘‘2.02”; rostrum, obtuse, attaining 2d coxa. Hairs on body inconspicuous 
“blunt to flattened,” sparse. Cauda tapering, bearing 2 pairs of lateral hairs on proximal half

Chief Distinguishing Characters. Length of body (2 or more), length of an- 
tenna (3 or more), length of III (8-10 times rostral IV-+V and twice cornicle 
length) and’number of caudal hairs (2 lateral pairs and 1 dorsal preapical pair).

Siphonophora minor Forbes, 1884:101. 
Capitophorus minor, Hottes and Frison, 1931a:284; Gillette and Palmer, 1934:152. 
Apterous Summer Vivipara. Pale greenish yellow; appendages pale proximally, dusky 
distally. Body length 1.10-1.20; hind tibia .60-.65; hind tarsal II .08; antenna 1.30; rostrum 
attaining 2d coxa. Hairs capitate on body; on antennal II to VI and tibiae hardly more than 
blunt; on body noticeable only on anterior and porterior segments. Cornicle cylindrical, im- 
bricated. Cauda tapering, rather acute at tip, bearing 2 pairs of lateral hairs and a single 
dorsal preapical one.

Fig. 314. Capitophorus minor 
Alate Vivipara. Head and thorax dark; abdomen pale greenish yellow with dusky lateral 
areas and dorsal patch; antenna dusky; cornicle, cauda and legs pale with tarsi and tips of 
tibiae dark. Measurements as in apterous vivipara. 
Ovipara. Apterous. Same as apterous vivipara except proximal two-thirds of hind tibia 
moderately swollen and bearing numerous large sensoria. 
Apterous Male. (Mounted on slide), body immaculate; appendages pale with tarsi and 
tips of tibiae dusky; antenna beyond base of. III black. Body length, 90; hind tibia .55; 
antenna 1.30, III .26, IV .19, V .21, VI .10-+.50, a few minute sensoria along posterior side of 
III, IV and V; cornicle .20. Otherwise as in apterous vivipara. 
Alate Male. Body length .90; hind tibia .75; antenna 1.6, III .37-.47, IV .24-.28, V .28-.32, 
VI .12+.45-.47, sensoria hardly tuberculate, 15-18 on III, 7-8 on IV, 7-8 on V. These males 
were taken in copula with oviparae which exhibit characters of this species. However, these 
males exhibit measurements agreeing with C. fragaefolii. They agree with alate males deter- 
mined as belonging to this species and described by Hottes and Frison (op. cit.). This ob- 
servation seems to throw some doubt on the distinctness of these two species. 
Collections. On leaves and stems of Fragaria sp. Colorado: Fort Collins.

Lectotype. Ill. Nat. Hist. Surv. Collection, Slide No. 3158. 
Chief Distinguishing Characters. Hairs on abdomen of aptera very sparse 
or absent except on posterior segments and short cornicle (.23-.33). 
Capitophorus oestlundi Knowlton 
Capitophorus oestlundi Knowlton, 1927d:235; Gillette and Palmer, 1934:153. 
Apterous Summer Vivipara. Bluish green to apple-green, slightly pruinose; cauda pale to 
dusky; cornicle and appendages pale except tips of tibiae and antenna beyond middle of V and 
tips of III and IV which are blackish. Body length 1.45-1.80; hind tibia .80-1; hind tarsal II 
.11-.13; antenna 2-2.65; rostrum acute, attaining 2d coxa. Hairs spatulate to fan-shaped or 
funnel-shaped, on body .03 long, numerous and conspicuous on all segments; on antenna and 
tibiae blunt to slightly capitate, very drooping and inconspicuous. Ocular tubercle inconspicu- 
ous. Eye prominent. Cornicle slightly clavate, often curved outward, cauda elongate-tapering 
or with slight neck, bearing 3 pairs of simple lateral hairs and 3 spatulate dorsal hairs. 
Alate Vivipara. Same in color and measurements as apterous vivipara except rostrum 
attaining between 2d and 3d coxae and hairs shorter and less expanded at tips.
