produced into triangular teeth, giving a serrate appearance; 
ovisac not developed, the eggs laid beneath the body; maximum 
length of mounted specimens examined, 6 millimeters; shape 
when mounted uniformly broad oval; antenne 9-segmented 
(normal for genus), sometimes with an indication of a division 
of the terminal segment; legs normal, rather slender for the 
group; with two pairs of large thoracic spiracles, and three 
pairs of very much smaller, simple, abdominal spiracles, the 
latter placed at the posterior apex of the body; derm pores all 
multilocular disk, possibly to be considered as of one type, but 
showing at least three sorts, as shown in figures, one (k) grouped 
along the body. margin together with a number of setz in rather 
distinct clusters, another (1) scattered over the body surface, and 
the third (m) present ventrally around the genital opening; 
ventrally near the margin with a heavy band of pores running 
around the abdomen as in typical Icerya; derm sete numerous, 
varying in size very decidedly, the largest in the tufts along the 
body margin, all long, slender, rather delicate and _hairlike, 
mostly with long stout sockets, but some with a very short and 
flat triangular base; anal opening a short, simple tube; with 
three small ventral cicatrices, the median much the largest. 
? Perissopneumon sp. 
I desire to place on record here collections of a few specimens 
of a monophlebine coccid of uncertain affinities in the hope that 
more material, including larve, fully developed adult females, 
and males, will be discovered by some collector at Singapore, as 
the correct placing of this species will be almost impossible with- 
out such additional material. The collection records are as 
follows: From rhizomes of Alpinia conchigera (Baker 9020) 
and from fruit scales of Garcinia mangostana (one specimen) 
(Baker 9023), both from the Botanic Gardens, Singapore, Octo- 
ber, 1917. I have had only the brief description of Perissopneu- 
mon ferox available for consideration in the generic placing of 
these specimens, but they appear to be more closely related to 
Newstead’s genus than to any other at present known to me. 
ORTHEZIIN4 
Genus ORTHEZIA Bosc d’Antic 
Orthezia insignis Douglas. : 
This species is represented among Professor Baker’s material 
by a few specimens collected on Clerodendron penduliflorum, 
Botanic Gardens, Singapore, August, 1917 (Baker 8941).
