 Gcsellsch. XLIV, 1894, 163, Taf. VII) lias described a youiig larva 

 which he thinks beiongs to either O. gibbosus or zonatus on account 

 of these species being taken in the same piace as the eggs. The 

 eggs were found on dry branches, which were used to fence a 

 road through a meadow in Austria. The smallest branches were 

 covered with eggs, sitting in rows; in the same place were 

 webs of small Arachnids. Some larvæ were found, fastened on 

 Podurids. The body is elongated, somewhat flattened, beset with 

 bristles. Only eleven segments were counted, but with the head it 

 would be twelve. On the last segment there was a fixing apparatus, 

 consisting of some hooks, and there were four strong spring-bristles; 

 the larva can walk as a Geometra larva, but it is also able to make 

 springs. The larva is described as metapneustic. Of moulh parts 

 are mandibles and maxillæ described. — Stein records (Stelt. Ent. 

 Zeit. X, 1848, 118) that he found O.varius Latr. {ftdiginosus Erichs.) 

 depositing its eggs on Equisetum limosum on a humid meadow in a 

 wood. 



The species of Oncodes are sluggish, they occur especially near 

 damp localities on leaves and dead branches. The genus includes 

 13 palæarctic species, one of which is found in Denmark.

 tellum shining black, rather den.sely clotlied with yellowish grey hairs. 

 Abdomen whitish, bone-coloured, tho front margins of the segments 

 more or less broadiy black, thus forming black, transverse bands, 

 which on the second and third segments are more or less widened 

 triangularly in tho middle and at the sides, in the following segments 

 only at the sides; on the second segment the middle spot is oflen 

 nearly quadratic. Venter bone-while, with small, black side spots on 

 the front margins of the segments, the spots sometimes produced 

 narrowly along the front margin. Abdomen clotlied with yellowish
