SUPPLEMENT TO PSYCHE. 



[December i^gs- 



Plates hardly visible. Anal orifice about 

 as far from base of median lobes as its 

 longer diameter. 



A 5 contains two long-oval embryos, 

 which are extraordinarily large, more than 

 half as long as the diameter of the ?. The 

 last joint of the antenna of the embrvo is 

 as long or a little longer than the three 

 before it together. 



Hub. — On Mesquite (Prosopis), niimer- 

 oiislj infesting the small twigs. Found by 

 Prof. Tourney about 4 miles west of Phoenix, 

 in Salt River Valley, Arizona, Sept. 1S95. 

 This singular little species has the scale 

 completely enveloping the ?, and so would 

 fall in Signoret's subgenus Targionia. In 

 several characters it resembles A. fersonatiis, 

 but it is very distinct from any species 

 described. It might have been thought 

 that the specimens were not adult, had not 

 matured embryos been found. It is found 

 on the leaves as well as the twigs. 



Dactylopius pandani, n. sp. — ? 3 mm. 

 long, i4 broad, pale yellowish brown. Legs 

 and antennae very pale yellowish brown. 

 Margin with stout cottony tufts as in /?. czV/-/. 

 Dorsum covered with white meal. 



$ turns reddish on boiling in soda, but 

 gives no crimson color. It becomes almost 

 colorless, but the contained embryos remain 

 bright yellow. Antennae S-jointed, joints 

 with whorls of hairs, joint i unusually long, 

 even a little longer than 2; 2 subequal with 

 3; 4 to 7 equal and shortest; S about as long 

 as I. Formula (iS) (23) (4567), but it might 

 almost as well be written (1S23) (4567.) 



Rostal loop reaching to level of base of 

 second pair of legs. Legs ordinary, tibia of 

 anterior legs about \ longer than tarsus, of 

 middle legs only about i longer. Femur + 

 trochanter a little longer than tibia + tarsus. 

 Claw small. Digitules slender, those of claw 

 with conspicuous round knobs, those of tarsus 

 with very small knobs. Trochanter with a 

 long bristle. Posterior tubercles hardly 

 noticeable, each bearing a bristle only about 

 i longer than those of the anal ring. Anal 



ring with the usual 6 bristles. Eyes promi- 

 nent, elevated on a stout base. Six patches 

 of small spines on cephalic margin. 



Hab. — At the sheathing bases of the leaves 

 of a young Pandanus, from Washington 

 Island, Mendana or Marquesas Group. 

 Found by Mr. Alex. Craw in the course of 

 his quarantine work. It has the lateral waxy 

 tufts short and stout as is ciiri, not long and 

 slender as in longispinus. From citri it 

 differs by the much shorter bristles of 

 posterior tubercles, and in the antennae, the 

 5th joint being if anything slightly longer 

 than the 4th or 6th. The length of the first 

 antennal joint is a noticeable feature. It is a 

 pleasure to record the first Coccid from the 

 Marquesas. 



MUTILLIDAE. 



Sphaerophthalma cargilli, n. sp. $, 

 Mittilla sp., Townsend, Journ. Instit. 

 Jamaica, Vol. 2, p. 168. (1895.) 



Length 10 mm.; head rather large, rounded, 

 cheeks unarmed ; thorax constricted at sides ; 

 abdomen pyriform, not much longer than 

 thorax, first segment broad and sessile on 

 the second. Eyes black, prominent; head 

 densely clothed with silvery-white hairs, 

 three or four long black hairs on the upper 

 orbital margin; antennae rufous, flagellum 

 darker. Thorax black, with short dense 

 black pubescence ; dorsum of metathorax 

 rufous, with an oval blackish central shade. 

 Upper anterior corners of metathorax with a 

 blunt tooth. Legs rufous, with very sparse 

 inconspicuous pale hairs. First abdominal 

 segment rufous, its apical margin black, its 

 basal portion with a few whitish hairs, its 

 apical portion with sparse long black hairs. 

 Second segment large, densely covered with 

 short appressed black pubescence, with two 

 transversely oval snow white spots on the 

 dorsum, separated from each other by nearly 

 twice the greatest diameter of either, and 

 about as far from the proximal as the distal 

 margin of the segment. Third, fourth and 

 fifth dorsal segments covered with silvery
