SUPPLEMENT TO PSTCHE. 



[September 1S95. 



Louisiana (exact locality not known) ; sent 

 by Mr. E. M. Ehrhorn. This is a species of 

 neotropical affinities, and must have attacked 

 the New Zealand flax since the introduction 

 of the latter into this country as an orna- 

 mental plant. It cannot be A. fhormii 

 Breme, Avhich has a while scale. In its 

 black exuviae it resembles A. vitis, from 

 which it differs in other respects. Of the 

 New Zealand species it only comes near yl. 

 sop/tome, with its 5 groups of glands and 

 branched plates, but that is different in its 

 lobes. It is very near to A. bowreyiy but 

 that has 4 groups of glands, differs some- 

 what in the tubular glands, and also mark- 

 edly in the shape of the scale. In the scar 

 it leaves it suggests A. personatns, which is 

 otherwise different. It resembles, also, A- 

 yiiccae Ckll. ined, but that has a different 

 scale, and leaves a scar without any black 

 ring. It is also allied to A. obsciiriis, but in 

 the long glands rather resembles A. perseae, 

 from which it differs in the grouped glands. 



Dactylopius aphyllonis, n. sp. — $ 3 mm. 

 long, of the general shape and appearance 

 of Z). citrt\ but without any caudal or lateral 

 tufts. Dorsum covered more or less with 

 mealy white secretion ; color of body when 

 freed from secretion olive-brown, antennae 

 and legs small and pale, inconspicuous. 

 Boiled in caustic soda it gives a blood red 

 color, after the manner of D. iiidicus and 

 D. xualkeri. 



Antennae 7-jointed; 7 much longest, a 

 little longer than 5+6; 5 shortest, 4 and 6 

 equal, next longest; 2 and 3 equal, next 

 longest, then i. Formula 71 (32) (46) 5, 

 Joints with sparse whorls of hairs. Color of 

 antennae very pale yellowish. In some ex- 

 amples, 4 is a little longer than 6, and about 

 as long as 3, which is not quite as long as 

 2; the formula is then 712 (34) 65. 



Legs pale brown, ordinary, femur about 

 as long as tibia; tarsus hardly half as long 

 as tibia. Claw large, stout, blunt, little 

 curved; digitules filiform. Mentum elon- 

 gate, with several short bristles. Posterior 



tubercles obsolete, the place of each indi- 

 cated by a large bristle. Anal i-ing small, 

 with 6 hairs, much smaller than bristle of 

 lobe. 



Hub. Wenatchee. Washington State, dlT 

 Aphylloii fasciciilatiim. Collected by Prof. 

 C. V. Piper. By its antennae and legs, this 

 is clearly not D. trifolii. 



Eriococcus neglectus, n. sp. — $ Enclosed 

 in a somewhat irregular waxy pyriform scale, 

 nearly 3 mm. long, shiny, pale ochreous, not 

 in the least divided into plates. The scales 

 or sacs, when boiled in soda, are seen to 

 be really composed of very closely-felted 

 threads. J oval or subpyriform, pale pink- 

 ish, about li mm. long; when boiled in soda 

 it becomes bright crimson. 



Antennae brown, joints distinct, 6 in num- 

 ber, 3 much longest, rather longer than 4 + 5, 

 which are subequal and shortest, 5 being 

 a Utile the shorter. 6 rather longer than 

 4, but hardly so long as 2. i about as long 

 as 2. Formula 3 (12) 645. In another ex- 

 ample, 2 is clearly shorter than 6. 



Legs small, pale brown. Trochanter with 

 two bristles. Femur moderately swollen, 

 with a short bristle on its inner side. Tibia 

 thick, stouter than tarsus, but about 4 

 shorter. Claw large, very little curved. 

 Tarsal digitules long, filiform. Digitules of 

 claw filiform. Posterior tubercles low and 

 rounded, with several bristles, one longer 

 than the rest; also round gland orifices. 

 Anal ring small, chitinous, without bristles 

 (or bristles easily deciduous.'). Mentum 

 obscurely timerous. Derm colorless. Eggs 

 pale lemon yellow. 



Hab. Las Cruces, N. M., on stems of 

 Atriplex canescens, looking very like the 

 Phoradendron seeds so commonly seen on 

 trees in this vicinity. The plants are thickly 

 infested by them, but I had entirely over- 

 looked them until recently, notwithstanding 

 that I pass within a few feet of them on my 

 way to and from College. The insect is 

 peculiar for its waxy scale, and might form 

 a new subgenus.
