The only other species described with aborted wings is subapterus, 
Thoms., Ofv., 1858, p. 375. This belongs to Thomson's second section, 
having the frontal lamina entire in front, the head dilated behind, &c. 
In ccecutiens the frontal lamina is produced into four lobes rounded at 
their apices, the two central being raised above the two lateral, and the 
elevated space bounded on each side by a depressed line ; the laminated 
space is aciculated, and therefore not shining. The ocelli should be at 
the anterior edge of the frontal lamina ; they are entirely obsolete, and 
in their place only two blind punctures are to be seen. This insect 
appears at first sight to be blind, but having examined it with great 
care, I can answer for its possessing eyes, which are in their usual po- 
sition, viz., low down on the antero-lateral part of the head. They 
are smaller than in the other species, flat, quite invisible from above, and 
not readily seen in any position, being nearly homogeneous with the 
rest of the surface, and having the facets very minute. I am indebted 
for this curious creature to Mr. Eye, who took two specimens on the 
23rd April, 1865, in a sandpit near West "Wickham Wood, Surrey. 
They were running actively about in the sunshine, vibrating their long 
antennje in front, after the fashion of Calodera or Callicerus, members 
of both of which genera were found with tliem. A specimen has also, 
I believe, been taken by Dr. Sharp near Edinburgh.
