Hitherto I have regarded this Dromius as a state, peculiar to the 

 Desertas, of the D. insularis (found in the sylvan regions of Madeira 

 proper) ; but a more careful inspection of it has induced me to be- 

 lieve that it cannot be referred absolutely to that species. It is 

 altogether a little larger, broader, and more parallel ; both its head 

 and prothorax are sensibly more developed ; and its elytra are 

 straighter at the sides, with their shoulders less rounded-off (or 

 more porrect), with their stria) almost unpunctured, and with their 

 postmedial fascia somewhat smaller and more hastate. I have taken 

 it beneath stones, in open spots, both on the northern and central 

 Desertas ; where, however, it would appear to be extremely rare.

I have given a corrected diagnosis of this Dromius, in order to 

 show the exact points in which it differs from the preceding spe- 

 cies (which is peculiar to the Desertas, and which I had formerly 

 regarded as a local state of the insularis). The D. insularis, how- 

 ever, as now denned, is essentially a sylvan insect, occurring in the 

 damp wooded districts of Madeira proper, and ascending to a high 

 elevation ; and it may perhaps be looked upon as the representative 

 of D. strigifrons of the Canarian Group. It is appreciably smaller 

 and less parallel than the D. oceanicus, its head and prothorax are 

 narrower, and its elytra are more expanded behind the middle, more 

 rounded-off (or less angular) at the shoulders, with their strife rather
