OBSEEVATIONS ON KRITISH COCCIDAE -. 

 WITH DESCEIPTIONS OF NEW SPECIES.— VIL 



iBY E. ERNEST GREEN, F.E.S., E.Z.S. 



During an inspection, by Mr, J, C. Fryer and myself, of a nurseiry 

 garden at St. Albans, Hei-ts, oji the 5th of May last, three species of 

 Coccidae — new to the British Isles — were found on plants recently 

 imported fi'oni Japan. One of these is a hitherto undesca-ibed species of 

 Lecanium ; the other two being ideatifiable as ^eroplastes ceriferus 

 Anders, and Oeropl-astes fiaridensis Comst., the last species having 

 charactei"s departiag from the ty2>e to ^uch an extent as to justify its 

 description under a varietal name. 



All these insects were living, and the Ceroplastes ceriferus was 

 covering a batch o£ ova ; but whether they could have survived the 

 rigours of a British winter remains jjroblematical. Both species of 

 Ceroplastes are widely distributed throughout the tropical and subtropical 

 regions. It is remarkable that Kuwana, in his several lists of Japanese 

 Coccidae^ has recorded not a single species of Ceroplastes, 



Lecamum lichenoides, sp. nov. (Fig. 1.) 



Adult female tiattish, deltoid (a) or broadly ovate, narrower in front, or 

 subcircular, occasioual examples being even broader than they are long. The 

 living insect is of an olivaceous grey tint above, marbled and mottled with 

 black, and with a series of black fasciae projecling inwards from the margin of 

 the abdominal area. The venter is dull castaneous, with conspicuous white 

 streaks of waxy secretion defining the stigmatic areas. Old dead examples lose 

 the greyish tints and assUme a more or less imiiorm dark castaneous colour. 

 Dorsum with a prominent medio-longitudinal and three transverse carinae. 

 Antennae (b) 9-jointed; 2nd joint longest; 7th, 8th, and 9th shortest, equal. 

 Limbs (c) relatively small, slender; tarsus two-thirds the length of the tibia; 

 tarsal digitules long, minutely knobbed; ungual digitules slightly dilated; 

 spines and setae few and small. Stigmatic clefts very shallow, scarcely appre- 

 ciable. Stigmatic spines strongly developed ; the anterior group usually with 

 two only, of which the uppermost is twice the length of the other {c) ; the 

 lower group with three spines, of which the median {d) is twic« the length of
