but otherwise I think my synonymy correct, while further syno- 

 nyms are still uncertain. 1 have also myself studied Zetterstedt's 

 types. 



P. nigrituliis is not rare in Denmark, Charlottenlund (Stæger), 

 Ermelund, Ørholm, Geel Skov, Ruderhegn, Nordskoven at Jægers- 

 pris (SchHck), Rørvig, Bogø south of Sealand (the author), on Lol- 

 land at Faaborg and in Aasø Skov (Schlick), on Funen at Odense 

 and in Jutland in Grejsdal at Vejle and at Frederikshavn, and on 

 Bornholm at Rønne (H. J. Hansen); the dates are ^Vs — ^Vs; a pupa 

 was taken in Ruderhegn in flood refuse in April (Schlick). 



Geographical distribution: — Northern and middle Europe at 

 all events down into Bohemia, towards the north to middle Sweden. 



2. Clialarus Walk. 



Small species of velvet black colour in the male, more greyish 



in the female. Head semiglobular, a little broader than tliorax, flat 



or a little excavated behind just from the eye- 



margin, and thus without any rim behind the 



eyes. Eyes separated in both sexes, very narrowly 



in the male, a little more broadly in the female. 



Vertex a little elevated, with three ocelli; the 



vertex has some short hairs and a pair of ocellar 



bristles, which are parallel and directed forwards, 



they are longer in the male than in the female; 



in the latter sex the frons distinctly hairy on the 



upper half. Eyes occupying the whole front side 



of the head, they are practically bare; in the male 



the facets somewhat enlarged, decreasing evenly 



in size towards the hind margin, in the female t.- o^ . .

very enlarged on the front part around the ch.spuriusS x\m. 



antennæ. Antennæ (Fig. 30) inserted in the middle 



of the head, near to each other, third joint short oval, rounded below, 



more roundish in the female, the second joint with a few long hairs 



above and below. Epistoma as in Pipiinculiis, but shorter on account 



of the less long head and a little raised above the level of the eyes. 



The mouth parts I have not examined, but probably they are as in 



Pipunculiis. Thorax quadratic, a little arched above, as in Pipiinculus 



with humeral knobs formed of the propleural parts; the thoracic 



disc and scutellum clothed with longish, or in the female shorter
