PTEROMALIDAE OF N.W. EUROPE 751 



sixth, distinctly longer than broad ; scape nearly or quite as long as an 



eye, reaching slightly above the vertex . . . . . . . 14 



Antennae with combined length of pedicellus and flagellum at most 11 times 

 the breadth of the head, but often less ; funicular segments most often 

 quadrate or slightly transverse, the proximal ones a little longer than 

 broad ; scape sometimes shorter than an eye and sometimes not reaching 

 the vertex ............ 15 



14 (13) Left mandible with 3 teeth, right mandible with 4. Propodeum with a strong 



median carina ....... acuminatus sp. n. (p. 762) 



Both mandibles with 4 teeth. Median carina of propodeum weak or absent 



(Czechoslovakia) ........ sp. indet. C (p. 757) 



15 (13) Head in dorsal view with temples slightly more than half as long as eyes, 



much as in the female of submarginahis, cf. Text-fig. 621. . . . 16 



Head in dorsal view with temples at least slightly less than half as long as eyes 18 



16 (15) y\ntenna with combined length of pedicellus and flagellum distinctly less than 



breadth of head. Head in dorsal view only 1 -8-1-85 times as broad as long 



genalis sp. n. (p. 757) 

 Antennae with combined length of pedicellus and flagellum about equal to 



breadth of head. Head in dorsal view approximately twice as broad as long 17 



17 (16) Antenna with first funicular segment as long as the second ; proximal 



segments of funicle slightly longer than broad, distal segments quadrate. 

 Larger species, length about 2 mm. . . . . sp. indet. A (p. 756) 



Antenna with first funicular segment shorter than the second ; proximal 

 segments of funicle very slightly transverse, distal segments distinctly so. 

 Smaller species, length about 15 mm. ....... 22 



18 (15) Antenna with all funicular segments except sometimes the sixth distinctly 



longer than broad ; flagellum very slender, proximally hardly as stout as 

 the pedicellus, only very weakly clavate ; pedicellus in dorsal view rather 

 more than twice as long as broad. Eyes separated by only 1-15-1-2 their 

 length. Propodeum with median carina absent or vague . sp. indet. I (p. 775) 

 Antennae with funicular segments not or only slightly longer than broad ; 

 if slightly so, then either the flagellum is distinctly clavate, or the pedicellus 

 in dorsal view is hardly twice as long as broad, and the eyes are rather more 

 widely separated. .......... 19 



19 (18) Antennae with scape distinctly shorter than an eye, at least not quite reaching 



the vertex, sometimes only reaching the lower edge of the median ocelius ; 

 combined length of pedicellus and flagellum slightly less than breadth of 

 head. Head in dorsal view with temples appearing slightly angulate 

 posteriorly. Malar space 0-3-0-47 the length of an eye ; eyes separated by 

 1-1-1-3 times their length ......... 20 



Antennae with scape as long or virtually as long as an eye, reaching the level 

 of the vertex or above it ; combined length of pedicellus and flagellum [not 

 known in lasiocampae sp. n.] about equal to or slightly greater than breadth 

 of head. Head in dorsal view (cf. Text-figs. 625, 643, 645) with the temples 

 tending to be rounded posteriorly. Malar space virtually or fully half the 

 length of an eye ; eyes separated by 1-35-1-6 times their length . . 21 



20 (19) Malar space about 03 the length of an eye. Mesoscutum weakly convex, 



about twice as broad as long .... germanicus sp. n. (p. 761) 



Malar space 0-4-0-47 the length of an eye. Mesoscutum moderately convex, 



not quite twice as broad as long .... peregrinus sp. n. (p. 764) 



21 (19) Head in dorsal view (Text-figs. 625, 643) with temples half or nearly half as 



long as eyes. Both mandibles with 4 teeth ...... 22
