206 TAXONUS GLOTT1ANUS. 



5. TAXONUS GLOTTIANUS. 



Taxonus glottianus, Cameron, E. M. M., x, 220 ; Cam.. Fauna, 



19, 4 ; Andre, Species i, 335 ; 

 Cat., 42,* 2. 



Black, half shining, very slightly pubescent on the head and thorax ; 

 knees, anterior tibiae and base of tarsi sordid testaceous. Wings 

 almost smoky ; costa and stigma black, the latter pale testaceous at the 

 base ; in the second cubital cellule is a small horny point. 



Length 3, alar exp. 6 lines. 



The black legs readily separate this insect from the 

 other species of the genus. Apart from the generic 

 characters it might almost pass for Emphytus tener. 



Apparently a very rare species. I have only suc- 

 ceeded in taking one female, which was got on 26th 

 May at Kenmuir Bank on the Clyde above Glasgow. 



Genus PCEOILOSOMA. 



Pcecilostoma, Dbm., Consp., 5. 

 Empyria, Brulle Hymen, iv, 666. 



Wings with two radial and four (sometimes only three) cubital 

 cellules. Lanceolate cellule with an oblique cross nervure. Transverse 

 median nervure received in middle of median cellule. Hind wings with 

 the recurrent nervure present, the transverse cubital absent, accessory 

 nervure shortly appendiculated. Antennae short, rarely longer than 

 abdomen, thin, attenuated at apex, rarely thick, with the joints trun- 

 cated at the apex. Abdomen oblong, widening out from the third seg- 

 ment ; blotch distinct. Eyes not reaching to base of abdomen. Clypeus 

 incised. Legs longish, patellso distinct ; claws bifid, or with a minute 

 tooth at the apex. 



The ground colour of the abdomen is usually black, 

 rarely luteous. When not entirely luteous the seg- 

 ments are lined with white or luteous, and the apical 

 segments may be entirely luteous. The legs with one 

 group are luteous, with another black, marked with 

 white at the knees. The stigma is luteous or black, as 

 the legs are black or luteous. With the black species 

 the dorsal abdominal segments bear white markings* 



The alar neuration is subject to considerable varia- 

 tion. With the black-legged species the first transverse
