58 Insecta. 



Daraus ergibt sich von selbst, daß die Artenzahl der Evaniinen in der Tro- 

 penzone ihren Höhepunkt erreicht und allmählich vom Äquator nach den Polen 

 hin an Reichtum abnimmt, eine Erscheinung, die mit der Verbreitung der Wirts- 

 tiere (Battiden) deutlich zusammenhängt. Ähnlich verhält es sich mit der zweiten 

 Gruppe; die dritte Subfamilie enthält fast nur Raritäten. 



Über das Alter ist man nur wenig unterrichtet. Die wenigen ältesten fossilen 

 Arten stammen aus dem Tertiär; Evan'ia- und BracJiygaster -B,este wurden im 

 Bernstein der Ostsee, also im Oligocaen gefunden; aus dem Miocaen Nordamerikas 

 stammt Äulacus hradleyi und Pristaulacus rohn-cri. Vielleicht gehört auch zu den 

 ausgestorbenen Arten ein vollkommen erhaltenes Tier aus Madagaskar, Evania 

 animensis, das im Kopal eingeschlossen zweifelhaft unter den recenten Formen 

 behandelt wird.

6 $ and 1 -' of M. vexator were bred, together with a number of the Clavicorn 

 beetle Diphyllus lunatus Fabr., from a fungus. As no other host or parasite appeared, 

 it is concluded that M. vexator is parasitic on D. lunatus. An allied species, Meteorus 

 obfuscatus, is parasitic on the Heteromerous beetle OrcJiesia micans. The rj of M. vexator 

 is now certainly known, and a description of it is given in the paper.

The author gives a long series of observations made during 1911 on a number of 

 epecies of ants, and of other insects, Arachnida, and Crustacea found in their nests. A 

 few of the many observations may be mentioned. In discussing Myrmecina graminicola 

 Latr., he states that in an observation-nest a 5 with deformed antennae diifered in 

 character and behaviour to the other v $ of the same species in the same nest. A mar- 

 riage-flight of Lasius niger Liun., observed on August 9"', is described; the nest was in 

 a masonry-pillar at the side of a gateway, and was entered by a hole in the mortar at 

 the base of the pillar: thousands of winged r " f and ^ij emerged from the hole at about 

 6 p. m., and climbed all over the pillar; a very few pairs were observed in coitu, and 

 these flew off together, but most of the winged ants flew off separately: sometimes the 

 5 $ helped them to start, tapping them with their antennae and pushing them to the 

 edge of the top of the pillar. Marriage-flights of the same species were seen on the 

 same afternoon by two other observers in widely-separated localities. A very small 

 Northern race of Formica fusca was found in the Island of Eigg, in the Inner Hebrides. 

 A marriage-Hight of Formica rufa, observed in Scotland on June lö"", is described; 

 copulation took place on the ground, no pair being seen together in the air. A large 

 and a small nest of the same species {F. rufa), 128 yards apart, were found to be in 

 connection with one another: food was being carried into the larger nest, but the ants 

 were carrying larvae from the larger nest to the smaller one. Among the observations
