Pheitacocciis Co:kerelli, n. sp. 



9 Scale red-brown, resting on a small white cottony sack projecting 

 a little behind the insect's body. Size small ; owing to ks position upon 

 the twigs, an accurate measurement could not be obtained. Cleared and 

 pressed under a cover glass, 2 mm. in diameter, a little narrow behind. 

 Derm colourless, mouth-parts yellowish-brown, antennse and legs slightly 

 tinged with yellow. Anal lobes well developed, rounded, with one long 

 bristle and several short spear-shaped spines and a few thin hairs ; they 

 also show several round gland pits, these due, perhaps, to some of the 

 spines being lost in process of clearing. No spines, pits or hairs on the 

 derm. 



Antennte 9-jointed ; measurements in /x, joints : 



Front leg coxa, 80 ; femur and trochanter, 200 ; tibia, 132 ; tarsus, 72 ; 

 claw, 28. Hab. — On Amfhinc/iier, Steamboat Springs, Colorado. 



Aspidiotus Hoivardi, Ckll. (^var. ancyhis ?), on ash (Fraxijius), 

 Denver, Col., July 28, 1902. The scales on the under side of leaf (along 

 the mid-rib) are very pale, while those on the upper side are 'dark. The 

 leaf on both sides along the mid-rib is faded to a light yellow, due from 

 the infestation. 



These were sent to Prof. Cockerell by Prof. Gillette, of the Agricul- 

 tural Experiment Station, Foit Collins, Col. A single scale on currant 

 twig, which proved to be Eulecanhini quercifex, Fitch. 



Phenacoccus Cockerel I i.,ow service berry (Amelanchier), at Gunnison, 

 Col.; coll. Prof Ball, Sept. 20, '92. In some respects these differ from 

 those secured from Prof. Gillette and described above. They are a little 

 larger; when boiled in liquid potash, they turn to a deep bright claret colour. 

 The females were filled with young larvee, and this might account for the 

 size. The insect is viviparous. 



Pidvinaria innumerabilis, subsp., Betheli, n. subsp. — $ Scale dark 

 brown, ovisac as in innumerabilis, cleared and pressed under cover glass 

 4 mm. in diameter. Derm practically colourless, slightly tinged with 

 yellow. Antennae 8-jointed ; measurements are, in /x :
