and triangular fourth lobe. A species with even lower and broader lobes 
than P. tesserata is P. fossor (Aspidiotus fossor Newstead, 1914), found on 
grape‘vine in Barbados, but doubtless of Old World origin. 
Pinnaspis siphonodontis n. sp. (Fig. 9.) 
Female scale about 13 mm. long, mytiliform, rather narrow, pale red-brown, 
somewhat translucent, the shrunken female beneath showing as a dark spot occupying 
about half of the large second skin, which is about 2 mm. long. 
Female yellowish, elongated; abdominal segments distinct, produced laterally 
into large tubercles, the posterior two on each side each bearing a pair of spine-like 
squames; caudal region with the median lobes prominent, almost contiguous, rounded 
apically, and with a single deep notch on the outer side; next to these on each side 
is a spine-like squame, then a pointed glandular projection, then two rather small 
lobes shaped like the blade of an axe, then a spine-like plate, then a pointed projection, 
then the margin is finely serrate for some distance, after which comes a very large 
spine-like plate, then a projection of the margin, and beyond, at some distance, a 
single spine-like plate, and beyond this a pair of such plates, the formula for the 
spine-like plates being therefore 1, 1, 1, 1, 2. Circumgenital glands in five groups : 
median with 4 orifices, anterior laterals 10, posterior laterals 9 to 11. 
Male scale a little over half a mm. long, parallel-sided, strongly tricarinate, but 
brown, with the same color and texture as the female scale. 
Hab.— In groups on upper side of leaves of Siphonodon celastrineus Griff. (Celas- 
trace), the scales nearly all oriented in the same direction, much in the manner of 
_ Hemichionaspis thee. Los Bafios, Philippine Is., Feb. 1, 1914 (C. F. Baker 2372). 
Related to Pinnaspis buat (Bouché), but readily distinguished by the 
double second lobe and the form of the median lobes. 
Neolecanium cribrigerum n. sp. (Figs. 16-19.) 
?. Perfectly flat, broad-oval, about 4.25 mm. long and 3.55 broad; no glassy 
or waxy covering; rich red-brown. (The larvae are much narrower.) Derm trans- 
lucent brownish after boiling, in the posterior region with scattered large glandular 
structures, shaped like an ink bottle, each emitting a very short bristle. In the 
abdominal region are six large patches which are more strongly chitinized than the | 
surrounding tissues, and are perforated with a number of small round gland-orifices; 
these patches are three on each side, arranged in a semicircle, in the middle of which 
are the anal plates. 
Mouth very small. Antenne rudimentary, without joints. A rather large 
circular orifice in the derm on each side laterocaudad of the antenne. 
No legs. Margin with a very few exceedingly minute simple bristles. 
Anal plates triangular, rounded at end, caudolateral side a trifle shorter than | 
cephalolateral. Anal ring appearing moniliform. 
Hab.— On Piper loheri, occurring on the leaves; Los Bafios, Philippine Is. 
(Baker 1754).
