 A single ? taken at Perregaux, Algeria, with Aphcenogaster 

 testaceopilosa, L. The specimen was of small size, perfectly spherical, 

 and of a brilliant crimson colour. It is not possible to determine the 

 species or to describe it.

covered with a layer of white secretion ; segments above widely separated and faintly 

 indicated, beneath they are very narrow and sharply defined. On the ventral 

 surface, between the thoracic and first abdominal segment, on each side, a large, 

 almost hemispherical, tubercle. Kostrum lying in an ovate cavity or recess. 

 Spiracles opening info large depressions. The foregoing characters are external and 

 can be seen without preparation. After treatment with potash and viewed by 

 transmitted light, the ventral ai'ea appears as shown in fig. 1. At A. A. are seen 

 tlie ventral tubercles with their strong internal walls. Mentum monomerous ; 

 filaments short, resting in a cavity formed in the chitinous wall of the thoracic and 

 first abdominal segment. At the base of the rostrum are two large elongated glands 

 (fig. 2) with faintly reticulated surface, and above them several others of the same 

 structure, but smaller and of irregular outline. Spiracles (fig. 3) very large. Dermis 

 thickly set with circular glands of various sizes. Anal ring very small, with 17 

 hairs. Diam., 10 m.m. High, 4 50 m.m. 



$ . Second stage closely resembling the adult, but the segmentation above more 

 pronounced and the colour pale yellowish-brown.
