But the proportions of the antennal joints and of the feet have 

 been taken as the distinguishing features of the above-named 

 species, and none of them agrees with D. affinis. Thus, in 

 D. adoniduvi, the second and third joints are equal, and the 

 j&fth is shorter than the sixth ; in D. citri the antennae are 

 somewhat similar, but the tarsus is almost as long as the 

 tibia ; and so on. Moreover, the habits of all these insects 

 are aerial, whereas D. affinis appears to be, at least principally, 

 subterranean. At some future time it may be found advisable 

 to unite, under the common designation of the " meal} -bu_;.i 

 proper," all the insects of this genus presenting a fringe of 

 cottony processes, and make them varieties of D. adonidum. 

 But for the present they may remain separate. 



Dactylopius lobulatus, sp. nov. Plate VI., figs. 1-3. 



Adult female yellowish-brown or sometimes reddish-brown, 

 covered dorsally with white cotton, and having a marginal 

 fringe of white cottony processes which are somewhat longer 

 on the abdominal segments. Length variable ; the specimens 

 seen average about xV^^- Antennae of eight joints, of which 

 the last is fusiform and the longest, the sequence of the rest 

 being second, third, sixth, fourth, fifth, seventh, first. Feet 

 rather long ; femur strong ; trochanter bearing one long hair ; 

 tibia cylindrical, with several fine hairs, and with two spines 

 at the extremity ; tarsus tapering, pubescent ; the tibia is two 

 and a half times as long as the tarsus ; upper digitules short 

 fine hairs, the lower pair only very short fine bristles lying 

 along the claw. Mentum conical, dimerous ; the abdomen is 

 truncate, and terminates in four inconspicuous anal tubercles, 

 each bearing conical spines and short setose hairs ; anal ring 

 large, compound, with six hairs. Epidermis bearing some 

 very small circular spinnerets and some short fine spiny 

 hairs : the spinnerets and hairs are more numerous near the 

 margins. 



Larva and male not observed. 



Hah. In Australia, under loose strips of bark of Eucalyptus 

 globulus. My specimens were sent by Mr. Froggart from 

 Bendigo, Victoria. E. globiilus is a Tasmanian tree. 



This insect belongs to the series of D. adonidum, and may 

 be distinguished from that species and from D. affinis chiefly 

 by the proportions of the antennal joints and by the anal 

 tubercles. These last are not conspicuous in the natural 

 state, appearing only as small rounded bosses on the margin 

 (just as in D. nipce, D. cocotis, D. albizzice, &c.), but after pre- 

 paration of the insect they preserve a dark solid appearance, 

 being seemingly more chitinous than the rest of the body. I 

 have already remarked upon a similar feature when treating 

 above of D. nipce. Very possibly D. lobulatus may hereafter
