4 MADEIRAN COLEOPTERA, 
6. Dromius arenicola. 
Dromius arenicola [script. arenicolus], Woll., Ins. Mad. 6 (1854). 
Inhabits, in abundance, the sandy plains and low rocky declivities 
of Porto Santo, in company with the Tarus suturalis: and it has 
lately been discovered by Mr. Bewicke in Madeira proper (which 
proves it to be a true species, and no mere insular modification ),— 
who captured two specimens on the upland plain of the Fateiras, 
during December 1856, 
7. Dromius obscuroguttatus. 
Lebia obscuroguttata (Anders.), Dufts., Fna Austr. ii. 249 (1812). 
Dromius spilotus, Dej., Spee. des Col. i. 246 (1825). 
impunctatus (Kby), Steph., Ill. Brit. Ent. i. 23 (1828). 
obscuroguttatus, MWoll., Ins. Mad. 7 (1854). 


Inhabits the mountains of Madeira proper, abounding beneath 
stones on the open grassy slopes, from about 3000 feet above the sea 
to the summits of the peaks. 
8. Dromius glabratus. 
Carabus femoralis, Mshm, Ent. Brit. i. 463 (1802). 
Lebia glabrata (Meg.), Dufts., Fna Austr. ii. 248 (1812). 
Dromius glabratus, Sturm, Deutsch. Fna, vii. 54. tab. 171.f. C (1827). 
et femoralis, Steph., Ii. Brit. Ent. i. 25 (1828). 
(p.), Daws., Geod. Brit. 13 (1854). 
negrita, Woll., Ins. Mad. 9 (1854). 




Inhabits Madeira proper, attaining its maximum at rather low and 
intermediate elevations. It is the D. negrita of the Insecta Made- 
rensia,—the D. glabratus of that volume being the European D. 
maurus. From a note recently communicated to me by Dr. Schaum 
of Berlin, it would appear that the two species have been generally 
confounded (as varieties of each other) under the name of glabratus. 
He had formed his opinion of their distinctness, however (in ac- 
cordance with the views of Megerle and Sturm), from a careful obser- 
vation of continental specimens; and it is satisfactory therefore to 
remark that I had arrived at the same conclusion in Madeira, where 
they both likewise occur. It was indeed from my knowledge that 
a large and a small state were universally received as mere forms of 
the D. glabratus, that I was induced to describe the larger Madeiran 
one (which I could not regard as a variety of the smaller) afresh: and 
so, adopting (in common with most entomologists) the title of gla- 
bratus for the latter, I called the former negrita. It is to the larger 
of the two, however (with the robuster head and antenne, less
