Insects. 1897 



Genus Gyeinus, Geoff. 



1. G. marinus, Gyll., Ahr., Erichs., Aube, Suffr. 



— natator, Fabr., not Linn. 



— aeneus, Steph., var. major, not Aub. 



— aeratus, Steph., var. minor. 



— dorsalis, Gyll., var. 



The G. aeratus, Steph., seems to be only a very small variety of marinus. 



2. G. natator, Linn. (Mus. Linn.), Gyll., Steph., Aube. 



— mergus, Ahrens, Erichs., Suffr. 

 Var. G. natator, Ahrens, Suffr. 



— substriatus, Steph. 



— cercurus, Schiodte. 



The G. natator, Ahrens, Suffr., substriatus, Steph., is a variety, in which the series 

 of punctures on the elytra have nearly disappeared. There exists a regular gradation 

 from these to the typical natator, Linn., mergus, Ahr. 



3. G. minutus, Fabr., &c. 



4. G. bicolor, Payk., Gyll., Curtis, Steph. 



— angustatus, Aube, var. 



The British specimens belong to the variety with the sternum and tip of the abdo- 

 men red : this has been described by Aube under the name of G. angustatus ; in the 

 typical specimens these parts are black. 



5. G. urinator, Illig., Aube. * 



— lineatus, Steph. 



Genus Orectochilus, Eschscholtz.

 which are found there ; nevertheless a short notice of such species as did come beneath 

 my observation may not be altogether unacceptable. It is singular that such a re- 

 markable locality, in such an accessible neighbourhood, should be so little visited by 

 entomologists ; for I am perfectly convinced, from what I saw of its Coleoptera, that

 of a thorough investigation. I here, for the first time in my life, took the veiy local 

 and interesting Berosus spinosus, which, in the stagnant waters of the old brine-pits, 

 may be met with in tolerable abundance. Under small stones, and on the mud of the 

 excavations, which are half dry, that very beautiful little insect, Notaphus ephippium,
