268 THE ENTOMOLOGIST. 



knobbed digitiile. Legs brownish yellow, hairy ; trochanter with two short 

 hairs. Antennte 8-jointed ; — 4, 5, and 6 subequal, and shortest ; 7 next 

 shortest; then 1, then 2; 3 and 8 longest. These differences are rather 

 insignificant, except the decided shortness of 4, 5, and 6. Joint 8 emits 

 several hairs, none as long as itself. Boiled in soda, they do not colour it 

 red or brown. The female, after soda treatment, is yellowish red. The 

 white secretion is in the form of long straight threads. 



Larva. — Elongate-oval, with parallel sides ; two caudal filaments, not so 

 long as diameter of body, and joined together by secretion. Colour of larva 

 yellowish brown. 



This species was found by Dr. Strachan, in his garden in 

 Kingston, Jamaica, August, 1892. 



D. liliacearum, Bouche, which has been found on Pancratium, 

 must be similar ; but so far as I can judge, from the very few 

 details published concerning it, it is probably distinct. D. cal- 

 ceolaria, Maskell, seems also to be allied to D. simplex. 



(7.) Dactylopiusfilci'me7itosus,n.s'p. 



On a plant resembling a Vaccinium, with entire mucronate 

 leaves, 20 mm. long. Found at Cockburn's Harbour, South 

 Caicos, Bahamas, by Dr. Hy. Strachan, June, 1892. In clusters, 

 rpany together, on the stem ; clusters 8 or 9 mm. across, com- 

 posed of about ten individuals. 



? . — About 3 mm. long, shape of Coccus cacti, grey, but covered with 

 white secretion. The female, boiled in caustic soda, turns black, and 

 gives off a purplish black colour. By transmitted light it appears not black, 

 but violet. The margin has a series of short hairs. The caudal tubercles 

 emit the usual filaments, which, however, are very short. Between the 

 tubercles, when the secretion is removed, four hairs, longer than the 

 tubercles, can be seen. The legs are very small. Tibia not nearly twice as 

 long as tarsus. Claw slender, with a very short knobbed digitule. Tarsus 

 with two long knobbed hairs as usual. Inner side of tarsus with a long, 

 rather stout hair, which extends as far as to end of claw. Femur as long, or 

 nearly as long, as tibia and tarsus. Trochanter with a long hair. Colour of 

 legs brownish. Antennae very short, with only seven joints : — 1 and 2 about 

 equal ; 3 and 4 equal, shorter than 2 ; 5 and 6 subequal, shorter still ; 

 6 shortest ; 7 long. 



Larva reddish. Eggs oval, with contents partly of a verdis-green 

 colour. 



The characters of this insect would remove it from Dactylo- 

 pius, as strictly defined ; but it is surely congeneric with 

 Maskell's D. alhizzice and D. acacice. I had, at first, referred it 

 to the genus Rhizococcus, sens. Comstock ; but, as Mr. Newstead 

 has pointed out to me, the terminal joint of the antennae is 

 Dactylopioid.
