LagaroceraSj Becker. 



There appear to be five species that fall within the limits 

 of this genus, of which at least three appear to be un- 

 described. They all agree with Becker's diagnosis very 

 fairly, except that in two of them the 3rd antennal joint is 

 broader than he figures for his type-species, and is more 

 simply a long oval ; there appears, however^ to be no good 

 reason for not placing them in his genus. 



L. megalops, Beck. 



There is a single specimen which agrees very fairly with 

 Becker's description and figure ; the dorsum is quite 

 blackened all over, so that the three stripes are here 

 confluent.

Lagaroceras anomalum, sp. n. 



There are several specimens of a species which very closely 

 resembles the above specimen in thoracic and abdominal 

 colour, in the legs and general facies, but is a little larger. 

 The differences are, however, marked and constant ; they are 

 (1) the triangle, which has a different form; it is not truly 

 leaf-shaped, as in the generic diagnosis, but is practically 

 triangular, with concave (not convex) sides ; it extends to 

 the front of head : (2) the antennae are relatively shorter, 

 though still nearly as long as the face ; the third joint is not 

 quite twice as long as the second and is about 1^ times as 

 long as broad ; it is oval in form, with the upper tip sharply 

 rounded. 



Size (excluding antennse) 3 mm. 



Cam. Coll., Durban [F. M.). 



Lagaroceras pulchellum, sp. n. 



This is a fine handsome species of the megalops group. 



Head (top view) : — As broad as thorax ; frons black except 

 anteriorly just above the antennse, where it is orange ; the 

 surface is dusted with greyish pollen and has many small 

 hairs ; the triangle is highly polished black and is of a 

 pointed leaf-shape, the sharp stalk extending right to the 

 base of the antennae ; the base is rounded and occupies a 

 little over f of the vertical breadth. The head-bristles are 

 well niarked ; the back of the head is black. Side-view : — 

 Profile a little more trapezoidal than normal, the line from
