THE WEST I^^DIAN SfECIES OF DACTYLOPIUS. 170 



4 ; 4 and 3 of equal stoutness. Joints emitting sparse whorls of hairs. Tibia 

 about as long as femur ; tarsus not half length of tibia. Tibia emitting 

 several short stiff hairs. Claw with curved clubbed digitules, longer than 

 claw ; no tarsal clubbed hairs seen. 



On Prosojns jidijlora. East Street, Kingston, Jamaicca. 

 September, 1892. Common on the ends of the twigs, &c. 



(£.) Variety. 5 . — Adult, much as in var. farinosus ; the place of the 

 bands of virgatus is indicated by pits or depressions in the secretion, 

 producing two pairs of thoracic and three pairs of abdominal spots or 

 patches on the back, the abdominal patches each emitting a hair. This 

 form is, therefore, intermediate between farinosus, in which tlie dorsal 

 surface is covered with white powder, and virgatus proper, in whicli the 

 secretion is locally absent, so as to give the appearance of bands. 



On Acalypha, on the leaves. Parade Garden, Kingston, 

 Jamaica. 



A specimen measured was Sg- mm. long; with the caudal 

 filaments, 2 mm. long. 



(c.) Variety. 5 . — Adult, about 4 mm. long, thickly covered with white 

 mealy substance. Caudal filaments thick, nearly as long as body. Lateral 

 filaments obscure, or none. Legs and antennae brown. Eye very large, its 

 inferior margin notched. 



On sweet sop {Anona). Kingston, Jamaica. 



This is very like yb,y. farinosus, but the caudal filaments are 

 longer. It may be worth while to state that in giving the length 

 of the caudal filaments in this species, the length of the longest 

 filament is quoted. I have noticed that the left filament is some- 

 times shorter than the right. 



(d.) Yar.Mimilis. 5 (not adult). — About 2 mm. long. Caudal filaments 

 white, rather thick with secretion ; less than 1 mm. long. Body pale 

 lavender-grey, with the segmentation distinct ; a moderate amount of mealy 

 powder, and no dark dorsal line, but some indication of a light one, due to 

 secretion. Legs and antennae pale brown. No lateral projections, but a few 

 hairs free from secretion, especially close to the caudal filaments, where they 

 are as long, or neaidy as long, as the filaments, and about seven in number 

 on each side. Caudal stylus between the filaments distinct, about quarter 

 length of filament. Eyes black and distinct. Antennae of 8 joints, — o longer 

 and more slender than 2, but hardly as long as 8 ; 4 to 7 subequal, and 

 shorter than 2. First joint with a few long hairs ; no very long hairs on 

 eighth. Claws with knobbed digitules, the knobs larger. Tarsus with the 

 usual knobbed hairs, but the knobs almost obsolete. Tibia with a row of 

 stout hairs or bristles on inner side, and a row of finer ones externally. 

 Tibia about twice as long as tarsus; and as long as, or even a little longer 

 than, femur. Later on, more fully grown individuals were observed, nearly 

 4 mm. long. Very young ones are yellowish. 



On Tvibulus cistoides. East Street, Kingston, Jamaica. 

 July, 1892. 



At first I thought this was a distinct species, but now I feel 

 sure it is only a form of virgatus. On September 29th, I found 

 undoubted D. virgatus in great abundance, young and adults, on 

 Tribulus cistoides, in East Street. The adults swarmed on the 

 fruits.
