Salisbury, i <$, i.ix.1962 (Graham). Ireland : Co. Kildare, Royal Canal, 1 J,

 Biology. Unknown. 



Pirene eximia Haliday 



(Text-fig. 273) 



Pirene eximia Haliday, 1833 : 338, $. 

 Pirene eximia Haliday, 1844 : 296, $. 

 Pirene eximia Haliday ; Thomson, 1876 : 190, $ [nee o"]. 



Type material. Syntypes (2 $) in BM(NH). LECTOTYPE, the second specimen 

 which bears a small green ticket, indicating Irish origin. There are several specimens 

 belonging to the same species in Haliday's collection, but not labelled as eximia, 

 therefore possibly not syntypes. 



The hind tibial pecten of male eximia resembles that of male penetrans except that 

 towards the base of the tibia its hairs are rather less numerous, and neither so closely 

 nor so regularly spaced. The pecten of the female resembles that of female graminea 

 (cf. Text-fig. 283). 



Britain, Ireland ; apparently rare. 

 Biology. Unknown. Imagines in July. 



Pirene pallidum sp. n. 



(Text-figs. 274, 278, 281) 



$. Head and thorax with fairly bright metallic reflections, green, blue- or bronze-green ; 

 gaster with less intense tints which tend to be bluish. Antennae black, with slight metallic 

 reflections which are most distinct on the scape and pedicellus ; tip of the scape pale ; radicula, 

 and apex of pedicellus, sometimes testaceous. Mandibles testaceous with their teeth darker. 

 Palpi testaceous. Coxae concolorous with the thorax ; trochanters fusco-testaceous, the fore 

 ones sometimes testaceous. Legs otherwise fuscous with the following parts testaceous : fore 

 femora at apex or mainly, apices of mid and hind femora narrowly, bases and apices of tibiae, 

 of the fore tibiae broadly, of the mid and hind tibiae narrowly ; tarsi slightly paler beneath. 

 Sometimes the inner aspect of the fore tibiae is testaceous, or the whole tibiae are of this colour 

 except for a dark mark on their outer aspect. Tegulae metallic. Wings hyaline ; venation 

 testaceous. Length (including ovipositor sheaths) 1-7 to 2 mm. 



Head in front view slightly broader than high ; eyes separated by somewhat more than their 

 own length, about 1-5 times as long as broad ; malar space slightly more than one third the 

 length of an eye. Antenna (Text-fig. 278) with scape, minus radicula, nearly five times as long 

 as broad, slightly shorter than an eye ; pedicellus in profile not quite twice as long as broad ; 

 flagellar segments one to four small and anelliform, without sensilla, their combined length 

 about equal to that of the pedicellus, all subequal in length, but the fourth a little broader than 

 the others ; segment five large, slightly transverse, up to 1-5 times as broad as long, provided 

 with sensilla, and with two to three irregular rows of bristles ; clava nearly as long as pedicellus 

 plus funicle, about 2-5 times as long as broad, with a rather strong constriction between its 

 first and second segments ; bristles of flagellum not unusually long. 



Thorax in profile (Text-fig. 274) distinctly arched dorsally. Mesoscutum and scutellum with 

 delicate, though distinct, engraved sculpture. Fore wing about 2-2 times as long as broad ;
