Face sMning black. One species only, 



3, Ehadiuegus. 



27 (22) Abdomen with rather long fine outstanding pubescence.

Fig. 353. — Pamponerus germanicus $. x 6. 



4. Pamponeeus. 



28 (19) Abdomen with obvious bristles in a row against the hindmargin of 



each of the four or five basal segments, even if only towards 

 the sides. 



29 (30) Basal joint of anterior tarsi very short (fig. 354). 





Fio. S5i.—EchtMstus cognatus S- X 10. 



Front femora beneath and middle femora anteriorly with strong 

 bristles. One well known and one doubtfully distinct European 

 species. 



ECHTHISTUS. 



30 (29) Basal joint of anterior tarsi not specially shortened. 



Ovipositor knobbed, and with only dense soft pubescence beneath. 

 Legs black, with the tibiae red ; front femora without, and middle 

 femora anteriorly with very few, strong bristles. 



Antipalus. 



31 (18) Ovipositor laterally compressed. 



32 (35) Thorax with the two rows of dorso-central bristles extending con- 



siderably in advance of the suture and sometimes with specially 

 long and dense pubescence on the middle stripe extending 

 forwards like a hog-mane to the front part. 



Abdominal segments with conspicuous rows of priehindmarginal 

 bristles. Eighth ventral segment of the male simple even if with a 

 conspicuous hindmarginal fringe. 



N.B.— The character of the bristly hairs on the fore part of the 

 middle stripe of the thorax is not always conclusive.
