STENUS FORMICETOBUM, MANNERHEIM, A BEETLE NEW TO BRITAIN, 96 



me to accept. Among these were a pair of Hypsicorypha juliae, Kr., 

 a remarkable cone-headed mantis, representing the Mediterranean 

 Eiiipusa, and Illthiopian ldulo)norpl>a. It is apparently confined to 

 Tenerife but is not common, and I was not fortunate enough to come 

 across one. In addition, the genial doctor gave me a series of 

 Anataelia canariensis, Bol., one of the most interesting earwigs known. 

 It was discovered many years ago by Don Anatael, under stones, near 

 the village of Bajamar, on the western coast of the island, and sent 

 for determination to Bolivar, who found it necessary to erect for it a 

 new genus, which he named Anataelia after its discoverer. It has the 

 antennae and sternum of the Labiduridae, and the legs of the Pygidi- 

 cranidae ; it is totally apterous and has a peculiar formation of 

 thoracic plates. The only other known species which resembles it at 

 all is (Jhallia jietcheri, Burr, a native of Korea, these two monotypic 

 genera requiring a subfamily to themselves, the Anataelijiae. Dr. 

 Cabrera has looked carefully for it in many parts of the island, and 

 has always kept his eye open for it when collecting beetles, but he has 

 never found it except in a certain portion of a plot of stony ground, a 

 few hundred yards long and about fifty broad, near the village of 

 Bajamar. This is surely one of the most remarkable recorded in- 

 stances of restricted distribution. 



Don Anatsel also gave me specimens of Forjicida cabrerae, Bol., 

 and F. guancharia, Heller, which I failed to find during all my 

 excursions, in spite of diligent search. I was equally unsuccessful in 

 my hunt for F. canariensis, Burr, and F. uxoris, Heller. These four 

 species of Forjicida are restricted to the Canaries, perhaps even to the 

 island of Tenerife, and all appear to be rare ; in all, the wings are 

 aborted and the abbreviation has attacked the elytra. It may be 

 necessary to form a special genus for their reception, and even 

 eventually be proved that they are all variants of a smgle species.

Stenus formicetorum, Mannerheim, a beetle new to Britain. 



By HEREWAKD C. DOLLMAN, F.E.S. 



I have much pleasure in introducing this Stenus to the British 

 list. Mannerheim's original description (published Bull. Mosc, 184B, 

 p. 83) is :— 



Stenus formicetorum, Mann. : plumbeo-niger, capite, thorace, elytrisque pro- 

 funde foveolato-punctatus, parce cinereo-pubescens, abdomine fortiter minus dense 

 punctato, immarginato. Longit. |-1 lin. Bis captus. S.nigritalo, Gyllen.yErichs. 

 vicinus, sed multo minor, brevior, et punctis multo majoribus in thorace et elytris 

 impressus, totus plumbeo-niger parce cinereo-pubescens. Antennae breviusculfe, 

 articulo tertio quarto parum longiore, totse nigrae. Palpi etiam nigri. Caput cum 

 oculis thorace fere sesqui latius, fortiter profundeque punctatum, fronte obsolete 

 late bisulcata, interstitio leviter elevato, oculis maximis globosis prominulis. 

 Thorax coleopteris dimidio angustior, lateribus rotundatus, basi apiceque lati- 

 tudine fere sequaiis vel ibi coleopteris dimidio angustior, latitudine summa paullo 

 longior, sequaiis, undique punctis majusculis fortiter impressus, interstitiis planis. 

 Elytra thoracis longitudine, eodem modo punctata, iequalia. Abdomen brevius- 

 culum, apicem versus sensim leviterque angustatum, parcius et subtilius quam 

 thorax et elytra punctatum, immarginatum. Pedes toti nigri. Eemina abdominis 

 segmeiito inferiore sexto apice rotundato. Mas latet. 



With the aid of Ganglbauer's table Mr. Eonisthorpe and I ran the 

 species down as S.forinicetoruni, Mannh.; his description of the species
