middle of the sides of the head. The moderately finely and longi- 

 tudinally rugulose thorax is fairly short and quadrate, gradually 

 narrowed from the rounded shoulders of the pronotum as far as the 

 meso-epinotal suture. The pronotum, neglecting the neck-like pro- 

 longation in front, is wider than it is long in the middle, very 

 distinctly marginate at the posterior angles and somewhat prominent ; 

 the pro-mesonotal suture somewhat impressed. The mesonotum is 

 very feebly arched, the anterior part quite flat, the median carinula 

 weak, distinctly marginate at the sides ; the declivous face slopes 

 downwards to the meso-epinotal suture fairly steeply and is feebly 

 concave, and when seen obliquely from in front appears arcuately 

 emarginate above, margined on each side by a sharp edge, which 

 ends above in a very blunt tooth or projection. The meso-epinotal 

 suture is narrow but deep. The dorsum of the epinotum is about 

 twice as wide at the base as it is long in the middle. It has in 

 addition to the longitudinal rugae a fine reticulate rugulosity, which 

 is also apparent to some extent on the lateral mai'gins of the dorsum 

 of the pro-mesonotum. The epinotal spines are straight, directed 

 outwards, backwards and upwards, fairly far apart, hardly longer than 

 one-third of the space between them ; the declivity of the epinotum 

 is fairly large, feebly concave, smooth and shining. The 1st segment 

 of the finely coriaceous-rugulose and shining petiole is trapezoidal,, 

 somewhat wider than long, or perhaps as long as wide, with strongly 

 rounded anterior angles ; the 2nd segment deeply and sharply grooved 

 above. The shining abdomen is exceedingly finely coriaceous and 

 almost smooth.

The type-species has not been recorded from our region, but is 

 possibly represented by the following variety : 



Var. maledicta, Forel.

" £ . 3 - 3-4 mm. Differs from the type of Mayr by its deeper 

 reddish colour, by the subopaque head, finely but not deeply striate 

 longitudinally. It is smaller and darker than the race lacustris, 

 Santschi, which, besides, has not a striated head. The eyes are fairly 

 convex." 



Assuming that the " base " of the dorsum of the epinotum in Mayr's 

 description is equivalent to the term " apex " (i. e. the brow of the 

 declivity) which has been used throughout this work, this form would 

 appear to differ considerably from the type- species in the structure
