base than the thorax; sides nearly parallel, slightly narrowed towards 

 the apex, the latter acutebj rounded; above convex, obtusely gibbose 

 below the base; each elytron with thirteen rows of fine punctures, the 

 first abbreviated, the outer row placed on the extreme lateral border, 

 interspaces smooth and shining, impunctatej on the surface of each 

 elytron are placed the following bright metallic green markings, bor- 

 dered with aureous; viz., two spots at the base, the first elongate, 

 situated halfway between the humeral callus and the suture, the second 

 placed mi the humeral angle; an entire, slightly sinuous and deeply- 

 grooved fascia just before the middle; a short, deeply impressed sub- 

 sinuous band, situated immediately behind the middle, and extending 

 from the outer margin more than a third part across the elytron ; an 

 oblique line commencing at the outer border, halfway between its 

 middle and apex, and running obliquely upwards nearly to the suture ; 

 and lastly, a narrow line covering the posterior two-thirds of the 

 suture itself. Body beneath variegated with bright metallic green and

Of this magnificent insect I know but two specimens — one in my 

 own collection, the other in the cabinet of Mr. Bakcwell. 



Genus Trichotiieca. 



Caput (tig. 5 c) exsertum, valde deflexum, fere perpendiculare ; oculis pro- 

 minulis, oblongo-ovatis, intus obsolete sinuatis ; antennis corporis longi- 

 tudini fere flequalibus*, gracilibus, filiformibus, ad apicem vix inrrassatis, 

 articulo tertio quarto breviori ; paipis maxiUaribus articulo ultimo ovate, 

 ad apicem attenuate. Thorax subcylindricus, lateribus non marginatus ; 

 antepectoris segmento antero-laterak (tig. 5 b) subtrigonato, angulo pos- 

 tico tnmcato. ScuteUum trigonatum, lateribus sinuatum, apice trun- 

 catum. Elytra thorace multo latiora, oblonga, parallela. Pedes modice 

 elongati. graciles; femoribus anticis (fig. 5 d) incrassatis, subtus dente 

 valido productis, intermediis subtus dente parvo armatis j tarais graci- 

 libus, articulo primo duobus sequentibus longitudine aequali, secimdo 

 elongato-trigonato ; ungue elongato, arcuate ; unguiculo (fig. 5 e) basi 

 dente valido annate. Corpus elongatum, subcylindricum, hirsutum. 



Type, Trichotheca hirtll, Baly. 



This genus ought to stand close to Adoxus, Kirby ; its elongated 

 body, slender filiform antennas, and incrassated anterior pair of 

 femora will separate it from the latter. 



Trichotheca Hrta. (Plate I. fig. 5.) 

 T. elongata, subcylindrica, pallide fulvo-fusco, pilis concoloribus suberectis 



* In the figure of this insect, as well as thai of ISpiphyma intestinorum, the 

 wi-tist has drawn the antenna; rather too long in proportion to the body.
