year, being rarest in tlie late spring ; in grass tufts and by sweeping ; at 

 Wherstead, Ipswich and Tuddenhani h'cu, in Suffolk ; as well as at 

 Brockenhurst and near Halstead in Essex. The only mention of it from 

 a lepidopterous host is that of Ratzeburg, who says he bred it from a 

 species of Psyche. Brischke bred it from Gymnetron cainpanulae in 

 Prussia; and in 1894 I bred two females from Coccinella septeiiiptinclata 

 at Ipswich.

 and sub-ovate, diffusely and obsoletely punctate and pubescent ; basal 

 segment sub-pyriform, sometimes with very strongly projecting spiracles, 

 at others laterally straight to the moderately broad apex ; terebra longer 

 than the basal segment. 



Head black, with the mandibles rufescent. Antennae piceous, with the
