252 Descriptions of British Species of Genus Gyrophana. 



of these specimens, kindly furnished me by him, that the above 

 description is drawn up. 



10. G. strictula, Erichs. Gen. et Sp. Staph. 191, 17 (1840). 



Kraatz, Ins. Deutschl. Staph. 360, 10 (1858). 



G. laevigata, Heer, Faun. Col. Helv. i. 310, 2 (1839)? 

 Fairm. et Lab. Faun. Ent. Fr. i. 459, 12 (1854). 



Piceous ; legs and antennae testaceous ; head, thorax and elytra 

 very distinctly alutaceous, and consequently but little glossy; eyes 

 but little prominent; antennae gradually stouter to the apex : thorax 

 considerably narrower than the elytra; moderately transverse, and 

 with two shallow longitudinal impressions, in which traces of the 

 dorsal rows of punctures are visible but very indistinct : elytra 

 with very minute scattered punctures; the humeral angle often 

 rufescent, as is likewise the apex of the abdomen. 



Male with four short ridges on the 6th abdominal segment ; 

 the 7th segment with the two outer teeth, or spines, of moderate 

 length, being about equal to half the diameter of the gently emar- 

 ginated interspace ; this latter with a small semicircular notch in 

 the centre, bounded on either side by a minute denticle. 



This species is about equal in bulk to the G. lucidula, but of a 

 more elongated form; the head and thorax decidedly narrower, 

 and the elytra longer than in that insect. It is rather larger than 

 G. manca, from which it differs not only in not having punctures 

 irregularly scattered over the whole surface of the thorax, but in 

 having that segment relatively smaller and narrower and more 

 distinctly margined. 



The head in G. strictula is less suddenly contracted behind than 

 usual, and the eyes are less prominent; its upper surface is gently 

 convex and presents small scattered punctures on either side of 

 the central line, which is impunctate. 



G. strictula of Erichson is identified by Dr. Kraatz, and by 

 Messrs. Fairmaire and Laboulbene, with the G. Icevisata of Heer, 

 and possibly these authors may have had an opportunity of exa- 

 mining specimens received from the Swiss naturalist; but judging 

 simply from his description, it appears to me very doubtful whether 

 it refers to the insect above described.

 Hampshire, April, 1860." — Dr. Power.
