THE WEST INDIAN SPECIES OF DACl YLOPIUS. 267 



a Dacfylopius. The roots were most severely injured, being exten- 

 sively corroded and excavated, and the excavations inhabited by 

 Dactylopii. Ants were swarming over the plants. 



This species of Dactylopius is presumably undescribed, but 

 the specimens were not sufficiently adult for descriptive j)urposes. 

 It has been recorded ('Insect Life,' iii. pp.413, 419) that a 

 probably undescribed Dactylopius infests the roots of tomato in 

 the same fashion in New Mexico. 



(4.) Dactylopius citri, Boisduval. 



All I know about the occurrence of this species in the West 

 Indies is derived from a few examples in the Jamaica museum, 

 contained in a tube marked, " Scale Insect on Crosset [?Gosset] 

 Coffee." The specimens are not in good condition, but they 

 appear to be the same as D. destructor, Comst., which is now 

 regarded as a synonym of citri. Comstock remarks that he 

 found destructor abundant on coffee-plants. 



(5.) Dactylopius brevipes, n. sp. 



In the natural cavities of pine-apples, bought in Kingston, 

 Jamaica, I find specimens of a small active Dactylopius, allied to 

 D. citri. 



It is pale pink in colour, and little over 1 mm. long. Body 

 oval, pink, sparsely white-mealy, segmentation distinct; no 

 bands or spots. Sides vpith white-mealy processes, seventeen 

 on each side, about equally long, except the four last on each 

 side, which are longer and thicker, but none nearly half the 

 length of the body. Legs and antennae pale brown. Tarsus 

 decidedly shorter than tibia; there is a "false-joint," quite 

 short, at end of tibia. Femur stout, and a little shorter than ^ i,revipes 

 tibia and tarsus. Four knobbed digitules ; those of the claw ^^^^^ eijarged)" 

 short, the other pair very long and slender. Tarsus with at 

 least two pairs of hairs on inner side, and three single ones on outer. 

 Tibia with seven hairs on inner, and seven on outer side. Femur with 

 four short hairs on inner side. Trochanter with one very long hair, 

 almost as long as femur, on its inner side. Antennae with eight joints, 

 slightly hairy : — 3 a little longer than 2, and about as long as 1 , or perhaps a 

 little shorter ; 4 and 6 about equal, 5 perhaps a little longer ; 6 and 7 equal, 

 and shortest ; 8 nearly or quite as long as 3. 



This insect appears to be a stumpy form, adapted for life in 

 the cavities of the fruit. It seems to be quite distinct from 

 D. hromelice, which was found on a pine-apple from Zanzibar. 



(6.) Dactylopius simplex, n. sp. 



Forming scattered patches of white secretion, quite irregular 

 in outline, on the upper side of leaf of Pancratium carihceum. 



? . — About 2 mm. long, oval, brown, with mealy white secretion ; 

 segmentation distinct. No lateral processes or caudal filaments. Tibia 

 nearly as long as femur ; tarsus about one-third length of tibia. Claw with
