occurred on the leaves only. As this habit does not obtain in any 

 other species of Lecanium found in this country, it was by the merest 

 chance I discovered them. 



Lecanopsis brevicornis, n. sp. 

 ? bright red, red or reddish-crimson ; ovate, narrowed in front, convex 

 above, flat beneath ; dermis very firm, especially so at margins ; segments clearly 

 j I A I defined. Antennae (fig. 1) black at the 



tip, extremely short, tapering, as long as 

 the tibia and tarsus together ; of seven 

 nearly equal joints, 1 much the voidest, 2, 

 4, 5, 6, each with a single hair, 7th with 

 four or five ; that on the 2nd joint much 

 the longest. Rostrum wide, uniarticulate ; 

 unexpanded filaments a little longer than 

 the legs. Legs (fig. 2) very short and 

 stout, black, shining ; tibiae much shorter 

 than tarsi ; digitules to claw and tarsi 

 simple ; there is a long hair on the tro- 

 2 3 1 chanter, and another at the base of the 



tibiee ; coxse very broad. The antennae and legs are broadly margined with dark 

 brown chitine. Spiracles (fig. 3) unusually large, in length about equal to the 

 antennae, shaped somewhat like a trumpet, broad at apex, narrow at base, where 

 they are attached to the centre of a large circular depression or cavity ; one side of 

 the cavity is almost entirely composed of minute circular spinnerets ; and outside 

 the margin of the cavity are several larger spinnerets. There are three tracheal 

 tubes radiating from each of the four spii-acles. Dermis at the margins of the body 

 ■with a broad band of circular spinnerets, but such almost entirely wanting in front 

 and behind. Anal cleft and anal dorsal lobes normal. 



In what is apparently the adult stage the $ covers herself entirely with a very 

 thin test, of a material closely resembling talc, which is irregularly cracked all over ; 

 the cracks are merely indicated by white lines, there is no actual separation of the 

 material. Long., 2-50 — 3'75 ; wide, 1"50 mm. 



Hah. : Snettisham Beach^ near King's Lynn, Norfolk ; two 

 specimens discovered by the writer, July 1895, in grass roots amongst 

 sand and gravel. Also two specimens at Llandudno, N. Wales, by 

 Mr. C. W. Dale, September 1S95. , 



Easily recognised by its very short, 7-jointed antennae ; short 

 legs ; large spiracles ; and by the $ covering her body at gestation 

 with a glassy test. 



Two of the specimens were covered with the test ; the other two 

 were naked, much smaller, and although living, were perfectly inert. 

 This latter character is most singular, and I can only surmise they 

 were adults at the ordinary period of test-making and gestation, and 

 consequently had no need of ambulatory power.
