LAMPEONOTA. 241 



little stout, their tarsi and tibiae often dark ; tarsal claws simple. 

 Areolet entirely wanting. 



Range. North America, Cuba, Europe, Sikkim. 



Probably the most natural position for this very distinct genus 

 is among the AC^ENITIDES, as was originally suggested by Haliday ; 

 the deep notauli and incrassate hind legs are very similar, but, 

 wherever placed, the unique conformation of the <S flagellum will 

 render that sex abundantly distinct ; both sexes are at once 

 known from the remainder of the LISSONOTIDES by the entire 

 longitudinal metathoracic carinae and, though with more un- 

 certainty (for some species of Lissonota and Meniscus are ex- 

 ceptions in this respect), by the absence of all trace of the outer 

 nervui'e of the areolet. 



170. Lampronota quintana, sp. n. 



J . A small black species, with pale legs, and the fourth and 

 fifth flagellar joints externally emarginate at the base. Head 

 nitidulous, with the vertex obsoletely punctate, deeply impressed 

 longitudinally on either side before the prominent and entire 

 eyes ; occiput bordered and deeply 

 emarginate ; face distinctly and 

 evenly punctate, deplanate and 

 strongly produced above, with 

 coarse white pilosity ; clypeus dull 

 testaceous, subglabrous and small, 

 apically truncate and basally semi- 

 circularly discrete ; mandibles 

 testaceous, with equal teeth ; 

 cheeks elongate and buccate, palpi 

 pure white. Antennae, longer than 

 body, filiform and not very slender; 

 the flagellum piceous beneath, its 

 basal joint hardly longer than the

Lampronota quintana, Mori. fourth and fifth joints distinctly 



constricted externally throughout 



their basal half, and the latter obtusely dentate at its apical 

 third. Thorax immaculate and nitidulous, with the finely sca- 

 briculous metanotum centrally bicarinate to near its apex, and 

 laterally strongly cariuate throughout above and below the 

 spiracles. Scutellum strongly nitidulous, with a few fine punc- 

 tures. Abdomen strongly shining, black, with the gastrocreli of 

 the second and third segments translucently testaceous, and the 

 extreme apices of the fifth and following white ; basal segment 

 gradually slightly widened throughout and laterally margined, 

 scabriculous and bicarinate to near apex, with the spiracles dis- 

 tinctly before its centre ; venter testaceous and plicate, valvulao 

 large and concolorous. Legs fulvous, with all the coxse, base of
