for the Microscope. 69 



pointed at the base, with the sides convex, and irregularly 

 toothed at the apex. (PI. VII., fig. 13.) 



504. SCALES OF TORTOISESHELL (Vanessa Urtica). 

 If the scales of the upper surface of the fore wing are 

 transferred carefully, they will represent the form and 

 arrangement of the scales of the wing, and make a most 

 instructive mounting. 



505. SCALES OF HUNTING-SPIDER (Salticus scenicus). 

 This common little spider is clad with beautiful scales, 

 for which it should be mounted whole. 



506. SCALE OF LEPISMA (Lepisma saccharind). This 

 insect inhabits old woodwork. The scales are nearly 

 ovate, with an acutely serrated apex, and longitudinally 

 striated. (PI. VII., fig. 8.) 



507. PODURA SCALE (Degeeria nigro-maculata}. Many 

 species of Podura yield scales ; this, which Mr. Mclntyre 

 calls the 'Speckled Podura,' he refers with some doubt 

 to the above named species. The insect appears to in- 

 habit cellars. (PI. VII., fig. 9.) 



508. PODURA SCALE (Macrotoma plumbea). This pen- 

 tagonal scale, with fine striae, is very distinct from the 

 usual form of Podura scales. (PI. VII., fig. 19.) 



509. SCALES OF DEATH-WATCH (Amobium tesselatuni). 

 The larva of this beetle furnishes two or three forms of 

 minute scales one hair-like, one with parallel, and one 

 with convex sides. 



510. SCALE OF GNAT (Culex pipiens). Minute scales, 

 nearly triangular, with longitudinal ribs. (PI. VII., 

 fig- 15-) 



511. SCALE OF WEEVIL (Curailio sp.\. Many of the 

 little 'weevil' beetles have scales distributed over the 

 elytra. One of these is found on beech-trees. (PL VII., 

 fig. 16.) 



512. SCALES OF ROSE WEEVIL Otiorhynchus picipes). 

 The scales on this weevil are arranged in circles, with 

 a scale in the centre. The circles in parallel lines along 

 the elytra. Attacks rose-bushes in the spring, and is com- 

 mon also in hedges. (PI. VII., fig. 22.) 



513. LITTLE PHYLLOBIUS (Phyllobius uniformis). The
