A shining and finely punctulate species with abdomen, except apically, 
red. Head subbuccate and constricted posteriorly; clypeus and mouth, 
except apices of mandibles, flavous; face with griseous pilosity ; clypeus 
arcuately discreted, deplanate and apically rounded. Antennae infuscate 
with scape flavous beneath, of @ shorter than body. ‘Thorax black and 
narrower than head, notauli distinct, pleurae sparsely punctate; metanotal 
areae incomplete, areola narrow and apically wanting. Postscutellum 
sometimes ferrugineous. Abdomen as broad and long as head and 
thorax, oblong-ovate or in @ pyriform; deplanate and red with anus 
from about centre of fourth segment black; first segment basally con- 
stricted, somewhat distinctly sulcate centrally and not impressed beyond 
the central spiracles ; petiole parallel-sided and in @ sometimes black, 
postpetiole abruptly explanate ; anus dilated, terebra short and infuscate. 
Legs slender and pale red with anterior coxae paler; hind tibiae and 
tarsi, or whole of the latter, subinfuscate. Wings slightly clouded with 
stigma and radius infuscate, radix and tegulae flavous; areolet wanting ; 
nervellus intercepted below centre. Length, 6—7 mm. 
One of the smallest of the genus, known by its subconvex body, dis- 
tinct longitudinal metanotal carinae, red abdomen and coxae with anus 
alone black and petiolar sulcus distinct, the red legs with only the hind 
tibiae apically above and claws black. Pfankuch says the type is lost. 
It occurs in marshy places about the middle of August in Sweden ; 
Germany, Italy, France and Belgium. Brischke bred (Schr. Nat. Ges. 
Danz. 1871, p. 68) a @ from larvae of Zenthredo (Taxonus) agilis in 
Prussia where he found, with the males, females with entirely and partly 
red thoraces. I cannot say that I am satisfied that the ¢ here placed by 
Desvignes in his collection, upon which all our records are based, really 
represents this species, which I do not know. Mr. J. N. Halbert gave 
me an analogous male, swept from reeds at Lake Namocka in Mayo, when 
I was there with him in July, rgro.
