LAMPEONOTA.

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

 Areolet entirely wanting. 



lianr/e. North America, Cuba, Europe, Siklcim. 



Proljablj the most natural position foi" this very distinct genus 

 is among the Ac.unitides, as was originally suggested by Haliday ; 

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

 wherever placed, the unique conformation of the d flagellum will 

 render that sex abundantly distinct ; both sexes are at once 

 known from the remainder of the Lissoxotides by the entire 

 longitudinal metathoracic carinse and, though with more un- 

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

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

 nervure of the areolet. 



170. Lainpronota quintana, sp. n. 



iS . A small black species, with pale legs, and the foui'th 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, \\'ith 

 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. Antennce longer than 

 body, filiform and not very slender; 

 the flagellum piceous beneath, its 

 basal joint hardly longer than the 

 scape and as long as second, the 

 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 centrallj" bicarinate to near its apex, and 

 laterally strongly carinate 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, valvula) 

 large and concolorous. Ler/s fulvous, with all the coxre, base of
