Förster describes the genus Lathromeris*) in Hym. 
Stud II part. In the table of genera (p. 87) he states ab- 
solutely correctly: — 
ve. Fühler siebengliederig mit einem Ringel und viergliedrigem 
Endolredt Ace at re ee ee Lathromeris.“ 
and in the description p. 89 he goesmore freely into this point 
without, however, giving any more detailed description 
of the species. Although this character in the antenne 
would appear sufficient to characterise the genus, it is 
allready dropped in 1858, in which year Reinhardt refers 
it to Ophioneurus. Dalla Torre refers it in his catalogue 
to Chaetostricha. Forster states that Lathromeris has a 
four jointed clavus; Ratzeburg figures the antenne of his 
Ophioneurus with a six (perhaps seven) jointed club, 
which does not appear very clear what could have given 
Reinhard the courage to let the genus be dropped. Just 
as difficult to explain is the reason why Dalla Torre has 
referred Lathromeris to Chaetostricha, as Walker points 
out that Chaetostricha has a six-jointed antenna, and a 
three-jointed clavus. Only a single exception, however, 
Schmiedeknecht, in Genera Insectorum, admits the genus 
and characterises it correctly with the seven jointed an- 
tenne and four jointed clavus. This however does not 
appear to have had any effect on the subsequent authors, 
for example Wolff. 
It does not thus appear that the genus has ever been 
found again here in Europe since Forster described it. 
However, on having a specimen to examine, there is not 
the slightest doubt that Forster is rigth, the four jointed 
clavus characterising it from all the other European ge- 
*) from lathros — hidden and meris = part; the name referring to the 
joints of the clavus which are so closely connected that the 
joints appear almost hidden,
