Female, I do not know the female but according to the de- scriptions it is similar to the male, but has some more bristles on the hinder part of the thoracic disc, thus differing herein from the other species. Length 5—5,5 mm, E. lutea is very rare in Denmark, only three specimens, all males, have been taken, at Horsens at the middle of July 1883 (H, I. Hansen). Geographical distribution: — Europe down into Italy; it seems to have its northern limit in Denmark as the above given locality is the northernmost known; it occurs also in England. IL Subg. Anacrostichus Bezzi. Black, shining, or somewhat greyish pruinose species of medium size and slightly hairy. Eyes separated in both sexes, the frons sometimes narrower in the male than in the female; all facets small. Antennae somewhat long, first joint longer than the second, the third elongated, Dorsocentral bristles uniserial (more or less irregularly), no acrostichal bristles, A humeral bristle, a posthumeral, a couple of notopleural, a supralaar and a postalar bristle present. There are somewhat long propleural and numerous metapleural bristles. Scu- tellum with four to six marginal bristles. Abdomen without bristles.
