AULACASPIS (DTASPIS) UOSM. 171 



ably, as seen under the microscope, but this is un- 

 doubtedly due to the position of the antennae under 

 the covering-glass. Legs (PL XIV, fig. 9) hairy; 

 digitule to claw and those of the tarsi faintly clubbed. 



Larva (PL XIV, figs. 10, 11) pale red to dull crimson. 

 Antennae (PL XVIII, fig. 7) of five joints, the fifth being 

 longer than the rest together. Formula 5, 1, 3, 2, 4. 



Ova translucent crimson (PL XIV, fig. 3). 



Habitat. Chiefly on the wild rose (Rosa canina, L.), 

 but has also been found on bramble (Rubus sp.). It 

 loves a sheltered hedgerow, and almost invariably 

 infests the stems and thicker branches of its food-plant. 

 Owing to this habit it is frequently carried with the 

 " standard briars " to our nurseries, and thus, inadvert- 

 ently, becomes a serious pest to cultivated roses, 

 especially those under glass. 



In 1887 Mr. J. W. Douglas recorded it from Exeter 

 on Rosa canina and Rubus sp. Mr. E. E. Green also 

 found it upon the same plants at Bearsted, Kent. In 

 Cheshire it is, next to Mytilaspis pomorum, the com- 

 monest of the indigenous Coccids, it being especially 

 abundant in the Chester and Knutsford districts. I 

 have received it in abundance from Dover (B. Tomlin), 

 Monellan, Killy Gordon, Ireland (Nicholson), and find 

 it common near Gloucester. It appears, however, to 

 be restricted in its distribution ; and I have failed to 

 find it in the north-west district of Leeds ; at Orping- 

 ton and Chislehurst, in Kent ; at Hunstanton, Heacham, 

 Snettisham, Ingoldisthorpe, Sedgeford, and Sandring- 

 ham, in Norfolk, or at St. Albans ; and both my friend 

 Mr. A. T. Gillanders and myself have found no trace 

 of it on any part of the vast estate of the Duke of 

 Northumberland at Alnwick. 



Distribution. Probably a European species, but is 

 found almost everywhere on cultivated roses. 



Life-history. Egg-laying commences in August, and 

 the larvae appear soon afterwards, but are most 

 abundant in the middle of September, and may then be 

 found in a more or less active condition. Before winter
