This as well as the succeeding two species fly very commonly into 
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 middling size, 
its lobes rounded externally and its tooth just marked in the shape 
of a slight obtuse rising at the bottom of the emargination. The 
ligula is very small and narrow, the paraglossae very large adhering 
to it and enveloping it fully and on all sides, the whole is very slight- 
ly cut away at the apical angles and slightly, but abruptly and ra- 
ther deeply, notched at the centre of the anterior 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 distin- 
guished differ in no other respect from the rest, I look upon them 
as curious varieties. 
51. Harpalus ( OpJionus) rugosiis N. 
H. prsecedenti simlllimus sed s^squi minor, magis rugosus, an- 
tennis robustioribus art. 5-11 ovatis leviter depressis, colore supra 
parum obscuriore, subtus dilutiore, pedibus albidis, coxis tarsisque 
brunneis, antennis totis castaneis ; long. corp. 3J lin. 
The small size and, upon close inspection, the other peculiarities 
just pointed out, readily distinguish this species from the former in 
spite of their close affinity in other respects. They are both equally 
common about Colombo.
