26 [February, 



approximately equal and longest ; 4th i^sually shortest, but occasionally equal 

 to 2nd and 7th. Rostral apparatus rather small. Legs well developed ; foot 

 (fig. 2-c) with a stout claw ; ungual digitules broadly spatulate, tarsal digitules 

 slender but conspicuously knObbed at extremity. Valves of anal operculum 

 (fig. 2-d) irregularly triangular, divergent ; apices with 3 or 4 stout spines near 

 the extremity. Anal ring with 6 stout setae. Stigmatic clefts obsolescent or 

 very shallow ; each with two small club-shaped spines (fig. 2-e). A series of 

 small circular pores, usually in pairs, extends from the margin to the opening 

 of the spiracles. Mai-ginal hairs simple, pointed, small and inconspicuous. 

 Derm with nmnerous tubular pores of the form represented at fig. 2-e, and with 

 transverse series of minute circular pores across the abdomen, marking the 

 junctions of the segments. Length, 3.50 to 4..50 mm. 



Male puparium resembling that of the female, except that the marginal 

 area is flatter and the median ridge more sharply compressed. Length 2.25 mm. 



On the leaves of various grasses and sedges. Camberley, Surrey. 



The mature insects were first observed in July. At that time 

 they were only just commencing to deposit their eggs. A specimen 

 found on the 10th November had the test packed with pinkish eggs ; 

 the insect itself, contracted to a fourth of its oiiginal length, occupying 

 the anterior extremity of the test. 



This species differs from P. bipartita in if s more slender form, 

 and in the greater number of plates that are comprised in the test. I 

 have had no opportunity of examining actual examples of Signoret's 

 species, but from his description and figure, it would appear that the 

 test of that species consists solely of two large pyramidal plates. 



The second species, of which I have been able to obtain three 

 examples only, is a more obscure insect. Though of a somewhat 

 different facies and habitat, it clearly falls within the genus Lecanopsis 

 of Targioni-Tozzetti, as extended by Newstead. My insect, being 

 characterised by well-developed antennae, I propose to call it Lecanojjsis 

 longicornis, in contradistinction to Newstead's L. brevicornis. 



Lecanopsis longicoknis, nov. 



Adult female (fig. 3-a), elongate, roimded in front, bluntly pointed behind; 

 flattish; segmentation inconspicuous. At first naked or slightly pulvei-ulent ; 

 afterwards more or less completely covered with loose white woolly secretion. 

 Antenna (fig. 3-b) 8-jointed : 3rd and 4th longest, approximately equal ; 6th 

 and 7th shortest ; 8tli equal to 2nd in two examples, to 5th in one example. 

 Limbs well developed ; tibia and tarsus rather long and slender, tarsus rather 

 less than half the length of the tibia. Foot (fig. 3-c) with stout falcate claw ; 

 ungual digitules stout, rather broadly expanded at extremity ; tarsal digitules 

 slender, each with a small knob at extremity. Mentum very short, consider-
