Lauipronota frontalis, Desv. Cat. 78, s .* 



A black species with distinctly nitidulous abdomen. Head with the 

 clypeus and palpi testaceous, and the mandibles obscurely fulvescent ; 

 face finely and densely punctate with the epistoma a little elevated and 

 the inner orbits narrowly stramineous throughout ; vertex finely punctate 

 and pilose. Antennae as long as the body, apically cur\-ed, infuscate 

 above with the flagellum testaceous beneath and its basal joints apically 

 distinctly nodulose ; scape piceous. Thorax with a pale testaceous cal- 

 losity before the radix ; notauli wanting; metathorax rugosely punctate 

 with the areola transstrigose, laterally strong and subparallel ; petiolar 

 area short and basally entire ; spiracles circular. Scutellum immaculate, 

 punctate and deplanate. Abdomen elongate-fusiform, narrower than the 

 thorax ; finely and not very closely punctate, strongly nitidulous ; first 

 segment subconstricted basally, and centrally deeply canaliculate to 

 beyond its middle ; second segment laterally reflexed ; anus subacute with 

 the valvulae cxserted ; petiolar spiracles very prominent. Legs bright 

 fulvous ; hind tibiae and tarsi infuscate, the former basally paler ; claws 

 finely pilose but not pectinate. Wings normal ; stigma and tegulae ful- 

 vous, radix testaceous; areolet triangular and petiolate; ncrvellus opposite 

 and intercepting below the centre. Length, 9 — 12 mm. 



I have taken the above description from the lour males, from Desvignes' 

 collection, in the British IMuseum.

9. Nitidulous, closely and alutaceouslv j)unclate, black. Head Ix^hind 

 the eyes narrowed ; mouth and clypeus alone dull stramineous. Antennae 

 almost as long as the body. Thorax immaculate with the mesopleurae 

 dull ; metathorax not transverse and, like the mesosternum, somewhat 

 coarsely punctate, petiolar areae basally entire. Scutellum black. Abdo- 

 men black; basal segment laterally strigose longitudinallv, more than twice 

 longer than apically broad, convex with discal transverse impression before 

 the apex ; second segment shining and glabrous with the apical margin 

 alone fulvescent and, like the apically closely punctate and immaculate 



* Lauipronota iwlabilis, Desv. (Cat. 79, <^), is the 9 of some Tryphnii and I shall hnpe to treat of it 

 more fully in the next volume of this work ; the single specimen in the British Museum, which is the 

 type of L. notabilii, is much broken. Hignell, of course erroneously, records it from Devonshire.
