ANISOLABIS ANNULIPES. 17 



basal ones reddish, then several very dark, the 13th and 

 14th quite pale, the apical two again dark (PL V, fig. 2). 

 Pronotum squarish, lateral margins lighter, anterior 

 half sometimes lighter also. Elytra and wings entirely 

 absent. Abdomen sub-parallel, without scent-folds on 

 the basal segments ; the last dorsal segment larger, 

 with depressed medial line. Legs flattened, testaceous; 

 femora and tibiae with a dark band. Callipers (PL V, 

 fig. 3, and text-fig. 2, no. 6) nearly in contact at base, 

 short, stout, without teeth, but with slightly wrinkled 

 inner margin, the right branch more incurved at the 

 tip than the left. 



FEMALE IMAGO (PL V, fig. 1).- -Resembling the 

 male rather closely ; usually, however, 2 or 3 mm. 

 longer. Callipers also longer, measuring about 3'4 

 mm. The two branches of the callipers alike, and 

 throughout their length more nearly contiguous than 

 in the male. The number of visible segments of the 

 abdomen, being two less than in the male, will be 

 found a useful feature for distinoniishino; the sexes.

Ecii. Burr ('Record,' 1912, p. 80) says that he 

 found numbers of A. annulipes under stones in a dry 

 river-bed just outside Funchal in Madeira. This was 

 on 30 September. The}^ generally occurred in pairs, 

 the female in three instances sitting in an apparently 

 dug-out depression in the earth, taking care of a pile 

 of about a dozen small oval cream-coloured eggs, a 

 little less than 1 mm. in length. 



XYM.rH.--As the species possesses neither elytra nor 

 wings, the nymph is more than usually like the imago, 

 unless it is so young as to be markedly less in size. 

 Perhaps a browner colouring may be a nymphal 

 characteristic. 



VARIATION. --Apart from considerable difference in 

 size between individual specimens, the greatest amount 

 of variation occurs in the dark bands on the legs, these 

 bands, indeed, being often entirely absent. It is, 

 therefore, unfortunate that the specific name should
