1. Raphidia Schneiderui, Ratzeburg. 
The following description is made from a type (¢) communi- 
cated by Ratzeburg. The species is certainly good. In the form 
of the head it is intermediate between R. xanthostigma and R. 
affinis ; in other respects, between R. cognata and R. media. 
Head elongate-oval, as long again as broad ; slightly contracted 
behind the eyes, the sides forming elongated curves; the neck 
short and contracted before the end; eyes larger and more pro- 
minent than in R. wanthostigma. The head is almost similar to 
that of A. affinis, but the sides are more strongly curved ; above 
more convex, somewhat depressed beyond the eyes. Palpi yellow- 
ish ; upper lip very small, yellowish ; clypeus large, striated trans- 
versely, yellow, brownish at the base; the colour of the head 
shining black ; the part between the eyes convex, rather strongly 
punctured, especially the transverse impressions situated behind 
the eyes; the points fewer on the sides towards the neck, absent 
in the middle, where there is a large smooth band running almost 
up to the transverse impressions. Ocelli approximating. The 
whole of the inferior surface of the head strongly punctured. 
Antenne yellow ; their apical half gradually brownish. Protho- 
rax as long as the head; somewhat contracted and depressed a 
little before the middle ; widened and inflated a little before the 
end; broadly yellowish at the sides, with short black hairs; nar- 
rowly bordered with yellow at the base and apex ; above shining 
brownish-black, striated transversely, rugose; a narrow reddish 
band on the inflated portion; two reddish spots on the sides ; be- 
yond the middle is an appearance of reddish spots. Meso- and 
meta-thorax shining brownish-black, marked with yellow in the 
middle in front. Abdomen brown, the tips of the segments bor- 
dered with yellow; oviduct as long as the abdomen; the last 
ventral segment with its apical border rounded (fig. 3, post, p.
