A single female specimen, found by M. Pittier de Fabrega, 

 lias been sent to us. It belongs to the " signata " group^ 

 but is quite unique from the very peculiar form of itscljpeus, 

 which is sharply pointed iu front.

We have received a number of specimens of this at different 

 times, all of them females, the greater number having been 

 collected by the Rev. J. Robertson. This also is a quite 

 isolated form, although belonging to the same group as the 

 last. The remarkable elongation of the head and thorax is 

 not found in any other species I know, and the conical prolon- 

 gation of the pygidium, which will probably be found to 

 characterize the female sex only, is also very peculiar. The 

 black vitlse on each side of the middle line of the prothorax 

 appear to be almost constant, but the elytral ornament is 

 extremely variable. In most of our specimens this consists, 

 in addition to the narrow sutural line, only of a small spot on 

 each side below the scutellum ; but these may enlarge and 

 unite into a large triangular patch enclosing the scutellum, 

 while an outer bar may appear extending obliquely inwards 

 from the humeral callus.
