218 PCEOILOSOMA NIGEICOLLE. 



pronotum, knees, anterior tibiae and tarsi, the basal half of posterior 

 and the tarsi at the base (broadly) white. Wings greyish hyaline ; 

 the first tr. cubital nervure is generally absent ; the costa is sordid 

 testaceous ; stigma fuscous to testaceous ; the tr. radial nervure is 

 received very near the apex of the third cubital cellule. The sheath 

 scarcely projects. Clypeus deeply emarginated ; labrum and palpi pale. 

 The abdominal segments are white at their juncture, rarely have they 

 any other white marks. Tegulse pale ; cenchri small, blotch large. 

 Length 3 3 lines. 



Differs from all the other species of this group by 

 the incised clypeus, whitish tibiae and tarsi, sordid 

 testaceous costa, half white tegulaa, deeply pilose head 

 and pale palpi and labrum. 



Ab. a. Tr. radial nervure interstitial, first tr. 

 cubital nervure present. 



I have a specimen intermediate as regards colour 

 between this insect and submuticum, having the iegs 

 with much less white than in the ordinary form. It 

 has no first transverse cubital nervure. 



This is a common Scotch insect, but seems to be 

 rare in England. It is found in June. The $ I have 

 never seen, although the female is abundant. 



Sweden is the only Continental locality recorded. 



9. PGECILOSOMA NIGRICOLLE, sp. n. 



Black, pilose ; four anterior knees, anterior tibiae and basal half of 

 tarsi, middle tibiae in front, and base of four posterior metatarsi testa- 

 ceous-white. Antennse very little longer than abdomen, thickish, 

 scarcely tapering towards the apex ; clypeus very slightly incised ; 

 wings almost hyaline ; costa and stigma black, the latter large, broad 

 compared to its length ; the transverse radial nervure issues from the 

 lower side, is straight and received in the middle of the cubital cellule ; 

 the first transverse cubital nervure is absent, the second (or third) 

 cellule is wide compared to the length, and wider at the apex than base, 

 its basal nervure is almost straight; that at the apex curved, the 

 cubital nervure is scarcely angled where the second recurrent nervure 

 is received. The claws have a blunt tooth not far from the base. <$. 



Length 2 lines. 



This little species might be placed in the genus 

 Harpiphorus, with which it agrees in the form of the 

 alar neuration, especially in the transverse radial 

 nervure issuing from the stigma at a distance from the
