✦ Synopsis

Non-innervated macrotrichia and microtrichia, thick-walled chemoreceptors and three kinds of thin-walled chemoreceptors are present on the antennal flagellum of Frenesia missa. One of the thin-walled receptors, the plate organ, is of a type not previously recorded for any insect. About four times as many plate organs are present on the flagellum of the male as on that of the female. They occur also on the maxillary and labial palps.

## Abstract The long antennal flagellum of __Neoconocephalus ensiger__ is covered with many sharp‐tipped hairs that appear to be non‐innervated; thick‐walled chemoreceptors, that may also have a tactile function; thin‐walled chemoreceptors of several kinds and coeloconic chemoreceptors. All of the

Male and female karyotypes are described of material from eastern Switzerland (2n d --60, 2n ? = 59; d XX/ 9 XO sex determination). At d meiotic metaphase ehiasma frequency is unusually high, more than half of the bivalents having two chiasmata; the recombination index is thus much higher than in ot
