DINARDA HAGENSI. 181 



weiden ; in Italy, very common in the north in the summer : also 

 throughout the Iberian Peninsula. It is found late into the winter, 

 .and perhaps hibernates. 



4. Epacromia strepens, Latreille. 



Stouter than the preceding, and generally darker in colour ; the 

 hind femora are especially thicker and shorter. The green colour is 

 less frequent in this species than in hi. thalaxfiina, and brown is 

 commoner. Length of body, 18mm. -20mm. (^ , 22mm. -28mm. $ ; 

 of pronotum, 4mm. 3 . 4-.5mm.-5-6mm. 5 ; of elytra, lSmm.-19mm. 

 3' , 20mra.-26mm. 2 ■ 



Abundant in sunny places in southern Europe ; commoner than 

 the preceding, but does not occur so far north. In Prance it has not 

 been recorded farther north than Bordeaux and Montelimar. It is 

 common all the year round in all Spain and Portugal. It is very 

 common in the north of Italy, and probably also in the south. It is 

 found also in Austria and the Tirol. Rudow {ZeiUrhr. fi'ir Gen. 

 Natitnr., xlii., p. 298, 1873) records the preceding species from the 

 sandhills of Mecklenburg, but his description agrees better with this ; 

 if it is true, it is a remarkably northern record. 



Both species take readily to flight and often Hy far and long, and 

 so are difficult to capture. 



Genus XVI : Mecostethus, Fischer. 



Differs from h]pacru)iiia in having the intercalate vein of the elytra 

 nearer to the ulnar than to radial vein ; the foveola? of the vertex are 

 impresso-punctate ; more or less triangular. There is a single European 

 species. 



1. Mecostethus orossus, Linne. 



Dark-olive green ; elytra olive-green, with a bright yellow stripe 

 ■ down the mediastinal and scapular areas ; vvings hyaline, with darker 

 veins, somewhat smoky towards apex ; hinder tibiae olive, yellow near 

 the base, with black spines. Length of body, 12mm. 3 , 26mm.- 

 80mm. 2 ; of pronotum, o-4mm.-4mm. 3 , 5mm. $ ; of elytra, 17mm.- 

 19mm. 3 , 18mm. -24mm. $ . 



Found in watery marshes in northern Europe; Lapland; Ireland ; 

 England, in the New Forest and Fens ; throughout France, though 

 less commonly in the south. Common in Belgium; found in the 

 northern part of Spain, in Aragon ; north of Portugal, Coimbra, 

 Oporto. It occurs as far south as the Alps, where it is found 

 at considerable elevations, as on the Righi, Avhere, however, it is rare. 

 In Lapland it occurs at Qvickjock, and in Skane. In x\ustria at 

 Modling, Prater, Marchfeld, Gmiinden, Langbathseen.

By HOKACE DONISTHORPE, P.Z.S., F.E.S. 



On May 13th last I took a small Dinarda in a nest of the rare ant, 



Formica e.rserta, at Bournemouth, which I at once recognised as new 



to Britain, and it turns out to be Dinarda haijenu, Wasmann, a 



species which is only found with /''. cnn'cta on the continent. I mav
