364 DactylopiincE. 



of the median and posterior limbs {figs, i, 5) ; and some minute inconspicuous 

 pores mingled with the others (see />. 2). Dimensions varying from 275 by 

 I '25, to 475 by 2'o mm. 



Young larva without prominent posterior lobes, but bearing a pair of long 

 caudal setee. Derm with longitudinal series of comparatively large circular 

 pores on both dorsum and venter, there being four series on the dorsum, four on 

 the venter, and a complete marginal series. Length 0*45 mm. 



Concealed beneath the imbricating stipules of a small stemmed bamboo 

 (? Teinostachyum attoiuattun) in the jungle above Nuera Eliya. 



Genus PEDRONIA, nov. 



Insects ovoviviparous. Derm with stout conical spines. Antenna six- or 

 seven-jointed, the terminal joint elongate. Without prominent chitinous anal 

 lobes. 



Type, strobilanihis. 



Superficially resembling Rhizococctts ; but differing from the Eriococcine 

 genera in the elongate terminal joint of the antennas and the absence of the 

 characteristic prominent anal lobes. 



PEDRONIA STROBILANTHIS, nov. 

 (Plate CXLIV.) 



Adult female (_/|§^. i), naked ; brownish red to dark purple-brown, with longi- 

 tudinal series of small colourless glassy spiniform paired processes arising from 

 stout sharply pointed conical spines arranged as in fig. 3. Antenna {fig. 5) 

 normally seven-jointed, but in many examples the number is reduced to six, 

 owing to a confluence of the second and third joints {fig. 6). Terminal joint 

 always much the longest. Formula of normal antenna 7, (1,2), 6, (3, 4, 5). 

 Formula of six-jointed form 6, 3, i, (2, 5), 4. Limbs stout ; tarsus shorter than 

 tibia {fig. 7) ; the two together scarcely longer than the femur (with trochanter) ; 

 tarsal digitules slender, slightly knobbed ; claw sharply pointed. I have been 

 unable to detect any ungual digitules. More or less definite eye spots are 

 noticeable on the anterior margin. Posterior extremity {fig. 4) with broadly 

 rounded lobes. There is a pair of stout spines (part of the marginal series) at 

 the apex of each lobe, and a longish seta from below the apex. Anal ring with 

 six stout sette. The dorsal spines, in the typical form, have bases almost as 

 broad as their length {fig. 9) ; but a form with longer and more slender spines 

 {fiS- 8) ^vas observed on the isolated hill of Namunakuli. This form may be 

 distinguished as var. tenuispina. Size of female insect averaging ro mm. by 

 o'6o mm. 



No ovisac is formed, the insects being ovoviviparous.
