364 Mr. H. W. Bates on the 
2. Agridia pheenicodera, nv. sp. 
A. subcylindrica, postice paulo dilatata, nigra, nitida; thorace — 
violaceo, lateribus cupreis ; elytris letissime viridibus ; capite 
angustissimo, postice valde elongato, haud attenuato. 
@ Antennarum articulo 8"? sequentibus multo breviori. 
Long. 5 lin. @. 
Very similar to 4. Batesii, the difference in the shape of the 
head and in the length of the eighth antennal joint in the ¢ being 
the only characters which induce me to believe it a distinct spe- 
cies. The head is much narrower and longer in proportion to its 
width than in the corresponding sex of 4. Batesii ; indeed there 
is no other species in the genus known to me which can be likened 
to it in point of narrowness, its greatest width not much exceeding 
that of the anterior part of the thorax. As in A. Batesw, it is 
greatly prolonged behind the eyes, but its sides are not straight, 
as in that species, but a little bowed outwards, and it is not per- 
ceptibly narrowed to the neck. ‘The thorax differs from that of 
A. Batesii in its colour being violet, passing into brilliant purple 
copper on the sides; the surface is not perceptibly wrinkled, and 
the punctures are in many parts confluent. The elytra are of the 
same rich silky metallic-green as in 4. Batesz. 
Ega. On foliage, one example. 
8. Agridia platyscelis, Chaudoir. 
Agridia platyscelis, Chaud. Ann. Soc. Ent. Fr. 1861, p. 110. 
A. angustata, postice paulo ampliata, nigra, nitida, elytris zneo- 
olivaceis, pedibus palpisque apice piceo-rufis; capite ellip- 
tico, glabro, pone oculos valde elongato, vertice convexo ; 
antennarum articulis apice setosis ; oculis vix prominentibus ; 
thorace capite paulo breviori, antice attenuato, subtus glabro, 
supra transversim strigoso et postice sparse punctato, lateri- 
bus lineatim punctatis et carinatis; elytris pone basin leviter 
sinuatis, postea ampliatis, apice truncatis, angulis exterioribus 
in dente productis, humeris rectangulatis; dorso punctato- 
striatis, punctis transversis et confertis. 
Long. 11 ling. 
Ega. Concealed in folded leaves on trees in the depth of the 
forest ; extremely rare. I met with females only; in this sex 
the eighth to eleventh joints of the antennze are much shorter and 
more slender than the preceding.
