This as well as the succeeding two species fly very commonly 

 into the rooms at night during the rainy weather. The present 

 spec, is a fine, comparatively large, robust insect. I may add to the 

 above description that the emargination of the mentum is of mid- 

 dling size, its lobes rounded externally and its tooth just marked 

 in the shape of a slight obtuse rising at the bottom of the emargi- 

 nation. The ligula is very small and narrow, the paraglossse very 

 large, adhering to it and enveloping it fully and on all sides ; the 

 whole is very slightly cut away at the apical angles and slightly, 

 but abruptly and rather deeply, notched at the centre of the ante- 

 rior margin. I may further notice that some of the individuals 

 before me have the apex of the maxill. palpi prolonged, cylindric 

 and slightly bent inwards ; as this is not a sexual distinction and 

 as the insects thus distinguished differ in no other respect from 

 the rest, I look upon them as curious varieties.
