122 The West American ScienHst. 



Ashmead). This species is sometimes very destructive to orange 

 trees in the Southern States, and also in the south of Europe. 

 It is the only described species known to me to occur on the Pa- 

 cific Coast, where it also infests orange trees. 



The Cypress Mealy-bug (Dactylopius Ryani, n. sp.). 

 Adult fern ale rounded-oval, or ellipsoidal, posterior end of abdo- 

 men convex; dull salmon-brown, legs and antennae lighter; very 

 sparsely covered with a white, mealy powder not concealing the 

 ground color; white cottony appendages along sides of body 

 very short; the two at the posterior end never more than one- 

 third as long as the body; antennal joints 2, 3 and 8 sub-equal in 

 length, longer than any of the others, the eighth twice as long as 

 the seventh; joint 1 is next in length and is much thicker than 

 either of the others; then 4, 5 and 7 sub-equal in length, joint 

 6 being the shortest, scarcely one-third as long as the eighth; tu- 

 bercle of proboscis one-half as long as the tibia, situated slightly 

 in advance of a line drawn between the front coxae; tarsi one-third 

 as long as tibiae, no tooth on underside of the claw, upper and 

 lower digitules knobbed at the tip; length of body nearly 3 mm. 

 (about one-eighth of an inch). 



Recently hatched female larva elongate-ellipsoidal, posterior 

 end of abdomen truncated and bearing two quite long white cot- 

 tony appendages between which is a pointed projection;, body 

 pale yellow, tip of proboscis-tubercle purplish ;antennae six-jointed, 

 but the first four joints not well defined, the sixth about as long 

 as the first three taken together. 



Egg elongate-ellipsoidal, minutely granulated; pale yellow. 

 The eggs are deposited in a mass of loose white cottony matter 

 which is sometimes twice as long as the body of the female. 



Named in honor of its discoverer. Mr. F. G. Rvan, of Ana- 

 heim, Cal., who reports finding it on Monterey cypress (Cupres- 

 sus macrocarpa), Chinese arbor-vitae (Thuja orientalis), and on 

 Norfolk Island pine (Araucaria excelsa). Later I received speci- 

 mens from Col. F. H. Keith, of the same place. This is the only 

 species of mealy-bug known to me to infest Conifers. 



The Sage Mealy-bug (Dactylopius Crawii, n. sp.). Fe- 

 male elongate-ellipsoidal, posterior end of abdomen slighty con- 

 cave; wholly light yellow; above thickly covered with a white, 

 mealy powder, the margins furnished with about thirty-four white 

 cottony appendages, the two at posterior end of body the long- 

 est, about equalling one-third length of body; antennal joints 2, 

 3 and 8 sub-equal in length and longer than any of the others, 

 the eighth twice as long as the seventh; the fifth is next in 

 length, then the fourth and seventh, the sixth and the first being 

 the shortest, but the difference in length between them and the 

 fourth and seventh is slight; tubercle of proboscis and the tarsi 

 as in Ryani; length of body 4 mm. (about one-sixth of an inch). 



The female brings forth her young alive, and simply secretes 

 a layer of white cottony matter, on which she rests.
