PTEROMALIDAE OF N.W. EUROPE 179 



the material on which this record was based has not been located, so that it cannot 

 be confirmed. Imagines appear mostly in June and July (one record for August). 



Callimerismus suecicus sp. n. 



$. Head and thorax dull green with some golden reflections here and there ; clypeus, lower 

 face, and pronotal collar, brassy-tinged ; gaster with green and bluish green reflections (which 

 are less intense than in fronto Walker). Mandibles mainly testaceous ; palpi brownish. Anten- 

 nal scape and pedicellus black with a greenish tinge ; flagellum black. Coxae concolorous 

 with the thorax ; trochanters mainly black, trochantelli testaceous ; femora black with a 

 greenish tinge, their tips testaceous ; tibiae testaceous with a fuscous stripe (most pronounced 

 on the mid tibiae) along their outer aspect, this stripe not reaching their bases or apices ; tarsi 

 fuscous, the mid and hind ones testaceous basally. Tegulae fusco-testacepus. Wings hyaline ; 

 venation testaceous, the parastigma and stigma of the fore wing brown. Length 1-85 mm. 



Structurally resembles the female of fronto (Walker), but differs in the characters indicated 

 in the key, which may be supplemented as follows : 



Head in dorsal view (Text-fig. 140) slightly more transverse (breadth to maximum length as 

 2-15 : 1, about 1-9:1 in fronto). Antennal scape relatively longer, its length slightly greater, 

 instead of slightly less, than the transverse diameter of an eye. Propodeum, medially, rather 

 less produced beyond the bases of the hind coxae. Basal tergite of gaster distinctly shorter 

 than its maximum breadth, in fronto about as long or only slightly shorter than its breadth. 

 The gaster proper in suecicus forms a short ellipse in dorsal view, about 1-25 times as long as 

 broad, whilst in fronto it is long-elliptic, 1-7 to 1-9 times as long as broad, but this difference 

 might be due to abnormal retraction of the posterior segments in suecicus. The sculpture of 

 the head and thorax in suecicus is slightly more irregular than in fronto ; that of the scutellum 

 and propodeum is also slightly coarser.
