270) much expanded ; the maximum breadth of the hind tibia fully equal to, 

 or even very slightly greater than, the breadth of the hind femur 



longicornis (Walker) (p. 331) 

 Female with antennae with only the first and second funicular segments 

 distinctly longer than broad, the remaining segments subquadrate or 

 hardly longer than broad ; clava as long as 3^ to 3! of the preceding funi- 

 cular segments ; scape hardly longer than an eye, 4-8 to 5-5 times as long as 

 broad. Male with mid and hind tibiae not obviously expanded ; the maxi- 

 mum breadth of the hind tibia slightly less than that of the hind femur

Type material. Ecrizotes monticola Forster. Syntypes in Zoologisches Museum, 

 Berlin. Lectotype designated by Boucek (1961 : 58) : it is the female nearest the 

 pin, staged on a block of pith, the latter bearing a red mark beneath the specimen ; 

 the pin bears two labels " 17/276 Frst." and (in Forster's handwriting) " Roseggthal 

 Ecrizotes monticola m. $ N. 8 u. 122 ". One antenna of the lectotype has been 

 mounted on a microscope slide by Novitzky.

 " " [Oland] and remounted by A. Jansson. It differs from the type of monticola 

 Forster in having the gaster slightly longer, the hypopygium projecting slightly 

 farther, and the ovipositor sheaths rather more exserted. It is difficult, without a 

 study of much more fresh material, to be sure whether more than just one variable 

 species is involved, as Boucek (1961 : 58) remarks.

Type material. Lectotype female designated by Graham (19566 : 263). In the 

 same paper I placed Henicetrus filicornis Thomson in synonymy with longicornis 

 Walker. I now believe that these two represent close but different species (for 

 distinguishing characters see key to species).
