II. SuBGEN. CAPEULAIS nov. subgen. 



The hinder portion of the body is thickened or vesicularly en- 

 larged in the ventral part, the thickened part being provided with 

 a longish depression below along the middle. Seen from the dorsal 

 side the body appears obovate (different from Eula'is Latreille [3] ), 

 becoming narrower posteriorly, the posterior surface of the narrower 

 part sloping downwards until it forms part of the ventral enlargement. 



Very characteristic for this subgenus is the shape of the palps and 

 of the fourth pair of legs. Both the palps and the fourth pair of legs 

 are greatly thickened in a different manner to those in Eula'is Latr. 

 The palps are very short and thick and possess but few of the 

 ordinary spines ; but, on the other hand, there are tivo exceedingly 

 thick and strong spines near the distal end on the outer side (on the 

 fourth and fifth segments). 



It is doubtful whether Capeula'is {C. crassipalpis n. sp.) is best 

 regarded as a genus or as a subgenus of Eula'is Latr. I consider 

 at present the latter interpretation best, as Gapeulojis agrees with 

 Eulals Latr., in regard to the skin, the eye-plates, the epimera, the 

 genital area, and the 3 anterior pairs of legs. The fourth pair of 

 legs agrees also in being without swimming hairs and without 

 genital processes.

Plate XVIII., figs. 16-22. 



Length of body about 1-6-2-1 mm. 

 Width „ „ l-3-l-5mm. 



Length of maxillary palps about 0-75 mm. 

 ,, leg I about 1'2 mm. 

 ,, ,, II ,, 1-8 mm. 

 „ III ,, 2-1 mm. 

 ,, IV ,, 2-3 mm. 

 The general shape of the body has already been characterised for 

 the genus. The colour cannot be seen, as the specimens are 

 decolourised by the alcohol. 



The epimera are relatively broad and closer together than in 

 most species of Eiolais Latr. Their shape, position and relations 

 to the maxillary organs, genital opening and " anus " may be seen 

 in fig. 16. 



Eyes. — The eye-plates exhibit the form typica of Eula'is Latr., 

 having the tw^o eye-capsules joined by a " bridge." The eye-bridge 

 has, however, an uncommon shape, and the nearest form I find to
