Hab. Mexico 23 (coll. Signoret 1), Orizaba (Bilimek, in Mus. Vind. Ces.: 2 ). 
We have not received a specimen of this insect, but Dr. Bergroth has communicated 
a Mexican example (?) of it for examination, and from this our figure is taken. 
N. ovatus is very like NV. dilatatus, but it has a longer, stouter, and more parallel apical 
process to the head (reaching to near the apex of the first antennal joint), and less 
acute antenniferous processes ; the upper surface is also more coarsely granulate and 
the connexivum rugulosely punctured. The abdomen in the female is more rounded 
at the sides than in the corresponding sex of NV. dilatatus, and has the terminal genital 
segment bilobed at the apex. 
The insect described by Dr. Bergroth (Ofv. Finsk. Vet.-Soc. Forh. xxix. p. 183) 
under the name WV. ovatus, Stal (a pair of which I have seen), belongs to a different 
species, V. pseudonymus, Bergr.* ; it is from North Carolina.

This species, the type (2) of which has been communicated by Dr. Aurivillius, is 
very like XW. litigiosus ; but it is more elongate and has stouter antennex (the third 
and fourth joints are broken off in the type). It is probable that there is some mistake 
about the Guatemalan record, or the insect would have been met with in the inter- 
vening region; Dr. Bergroth, however, assures me that he has seen a Guatemalan 
specimen of it.

Of this species I have seen about eighty examples, mostly from Capetillo and the
