80 Rev. T. A. Marshall's monograph of 



in the exsertion of the terebra, the obsolete suturiform 

 articulation, and the trapezoidal shape of the •2d cubital 

 areolet. Wesmael described three species, forming the 

 last section of his Ejcothecus, all of which appear to be 

 British, and, with the exception of exsertor, Nees, identical 

 with those established by Haliday. 



(2) 1. Hind femora tipped with black . . . • 3. exsertor, Nees. 

 (1) 2. Hind femora entirely testaceous. 



(4) 3. Stigma testaceous, darker at the outer angle 4. cunctator, Hal. 



(3) 4. Stigma fuscous, the inner angle testaceous ; 



in one case wholly fuscous. 



(6) 5. Segment 3 dull, minutely aciculated . . 1. excuhitor, Hal. 



(5) 6. Segment 3 shining, smooth, or nearly so. 

 (8) 7. Stigma ^ fuscous, unicolorous ; terebra J 



as long as i abdomen . . . . . . 5. vestigator, Hal. 



(7) 8. Stigma J bicolorous ; terebra J as long as 



J abdomen . . . . . . . . . . 2. umbratilis, Hal. 



1. Clinocentrus excuhitor, Hal.

Black; mouth, orbits, mesotborax beneath, legs, and a line 

 before the wings, testaceous ; abdominal segments 1 — 3 longi- 

 tudinally rugtilose ; segment 1 obconic ; stigma bicolorous ; terebra 

 ? f as long as the abdomen. Length, 2 — 2f ; wings, 4^ — 5^ lines. 



Clypeus testaceous, palpi paler ; antenna as long as the body, 

 33 — 36-jointed (35- in my specimen), black, joint 1 beneath, and 2 

 at the apex, testaceous ; metathorax not areated, rugose ; abdomen 

 hardly longer than the thorax, obovate, segments 1 — 2 longi- 

 tudinally rugulose, with punctulate interstices, 3 more finely 

 sculptured, nearly smooth at the apical angles, the hind margin 

 narrowly testaceous ; the other segments smooth, almost entirely 

 retracted beneath the 3d, with similar pale margins ; segment 1 

 almost twice as wide at the apex as at the base, shorter than twic 

 its apical width, with a medial carina which is bifurcate at the 

 base ; wings hyaline, stigma fuscous, its inner half testaceous, J . 

 The (J has the suturiform articulation more completely effaced, the 

 abdomen narrower, and sometimes a rufescent patch on the meso- 

 thorax. 



Taken by Haliday in woods, England and Ireland; by 

 me near Barnstaple. Wesmael found a ? at Charleroi.
