ovisac. From the external characters I supposed 

 it to be P. camellicola, Sign. But a more careful 

 examination showed the antennae (fig. Sa) to be 

 8-jointed, which precludes this determination, 

 camellicola being credited with six joints only, of 

 which the 3rd is remarkably long. The antennal 

 formula in the species under examination is 3, 2, 

 4 (1, 8), 5, 6, 7 ; the 4th joint without hairs. The 

 marginal hairs of the body (fig. Sb) are flattened 

 and divided at the tips, but lying edgeways to the 

 plane of the body, they often appear to be simple 

 and tapering. Mr. Newstead tells me that speci- 

 mens from Camellia in his collection also prove 

 upon examination to have 8-jointed antennae. AVe 

 are fortunately saved the necessity of erecting a 

 new species for this insect, it having been already (as I am iuformed 

 by Mr. Newstead) described and figured by Prof. Westwood (Gar- 

 dener's Chronicle, 1870, p. 308, fig. 52) under the name of Coccus 

 -flocciferus. It is probable that the examples recorded by Mr. J. W. 

 Douglas as occurring on the orchids Oncidium papilio and Calanthe 

 natalensis, at Kew (Ent. Mo. Mag., April, 1887, p. 243), and others 

 from Exeter on Camellia (Ent. Mo. Mag., September, 1886, p. 81), 

 which were determined from external characters only, will be found 

 to be this same species. It is, therefore, doubtful whether the true 

 P. camellicola really occurs in the British Isles. 



Dacttlopius citri, Boisd.— This is almost an omnivorous species, 

 and quite cosmopolitan in its range. I noted the insects in all stages 

 upon fifty or more different plants at Kew. 



[Mr. G. JNicholson, the Curator, has recently sent me leaves of 

 Hedera amiirensis infested with this species ; and, as they were 

 gathered from the outside of Museum No. 2, are of gi'eat interest, as 

 being the first recorded occurrence of this pest in the open air in 

 England. It is hoped the first hard frost will kill off the whole 

 colony.— E. N.] 



Dactylopius longispinus, Targ.-Tozz. — This species occurred 

 on Stangeria schizodon (from Nsita,\), Flacourtia sepiaria (from India),. 

 Adiantum, and several other plants. Mr. Newstead informs me that it 

 has not previously been recorded from the British Isles. But there 

 seems to be some confusion about the identity of the several species 

 of Dacti/lopius that occur commonly in plant-houses. This is uii-
