2. A. foveicollis, lata, depressa, atra, acneseens, thorace latitudine duplo breviore, lateribus valdc rotunda- 
tis, reticulatim punctato, fovcis quatuor magnis transversim positis irupresso, elytris thorace baud latioribus, con- 
fertira fortius granulatis, fortius margioatis, parallelis, postice suboblique attenuatis et rotuudatis. Long. -26. 
Sacramento valley, Mr. Rath von. Only differs from A. e x p an s a by the thorax having 
the foveas deep instead of obsolete, and by the punctures being a little stronger, both on the 
thorax and elytra: the front is hairy, and concave, but less deeply than in the next 
species. 
3. A. strigata, lata depressa nigro-aonca, smpe cyaneo-variegata, thorace latitudine fere duplo breviore, la- 
tcribus rotundatis, angulis posticis subreetis fortius reticulatim punctato, utrinque pone medium oblique imprcsso, 
elytris thorace baud latioribus confertiiu fortius granulatis, fortius inarginatis, parallelis postice suboblique attenuatis 
ct rotundatis. Long. -17—-25. 
PAnthaxia mneogaster Lap. & Gory, Mon. Bupr. 2, 32; tab. 7, fig. 44. 
Fort Tejon, California; Mr. Xantus. Front moderately concave, hairy. The sides 
of the thorax are less rounded than in the two preceding; there are no foveae, but on 
each side behind the middle a strong oblique impression running inwards towards the 
base: the punctures are strongly marked, and there are besides fine elevated lines, having 
a general longitudinal direction, connected together, forming elongate meshes: the disc is 
feebly channeled behind the middle. Body beneath greenish, abdomen shining, reticulate 
with punctures. In some specimens the disc of the thorax is darker than the sides. This 
is perhaps A. mneogaster Lap. cfi Gory, but the description gives no definite characters 
by which to separate it from allied species. 
4. A. imperfecta, Iatiuseula, depressa, nigro-amea, thorace latitudiue duplo breviore, antrorsum angustiore, 
lateribus rotundatis, angulis posticis obtusis, reticulatim punctato, valde quadrifovcato, postice versus medium strigis 
clevatis baud connexis, elytris granulatis, fortius marginatis, parallelis postice angustatis ct rotundatis. Long. -24. 
One specimen collected at Santa Fe, New Mexico, by Mr. Fendler. The sides of the 
thorax are more broadly rounded, especially before the middle, producing thereby the ap¬ 
pearance that the thorax is more narrowed in front, than in the preceding species: the 
sculpture is singular, the ordinary reticulation is not strong, and behind, towards the mid¬ 
dle, is broken up into undulating elevated lines having a general transverse direction, and 
not connected. The front is hairy, scarcely concave. 
5. A. rotifer, Iatiuseula, depressa, nigro-amea, thorace latitudine duplo breviore, antrorsum angustiore, la- 
tcribus late rotundatis, angulis posticis obtusis, fortius reticulatim punctato, obsolete quadrifovcato, elytris granu¬ 
latis, fortius marginatis, parallelis, postice angustatis ct rotundatis. Long. -22. 
One specimen with the preceding. Differs from A. imperfect a by the faint fovem 
of the thorax, and by the reticulation being strong and regular over the whole disc. 
These two differ very much in the same manner as A. expansa and foveicollis, and
