2. A. foveicollis, lata, depressa, atra, enescens, thorace latitudine duplo breviore, lateribus valde rotunda- 
tis, reticulatim punctato, foveis quatuor magnis transversim positis impresso, elytris thorace haud latioribus, con- 
fertim fortius granulatis, fortius marginatis, parallelis, postice suboblique attenuatis et rotundatis. Long. -26. 
Sacramento valley, Mr. Rathvon. Only differs from A.e x pansa by the thorax having 
the fovese 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-enea, sepe cyaneo-variegata, thorace latitudine fere duplo breviore, la- 
teribus rotundatis, angulis posticis subrectis fortius reticulatim punctato, utrinque pone medium oblique impresso, 
elytris thorace haud latioribus confertim fortius granulatis, fortius marginatis, parallelis postice suboblique attenuatis 
et rotundatis. Long. -17—-20. 
2Anthaxia exneogaster Lap. & Gory, Mon. Bupr. 2, 32; tab. 7, fig. 44. 
a 
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 foveze, 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. eneogaster Lap. & Gory, but the description gives no definite characters 
by which to separate it from allied species. 
4. A. imperfecta, latiuscula, depressa, nigro-zenea, thorace latitudine duplo breviore, antrorsum angustiore, 
lateribus rotundatis, angulis posticis obtusis, reticulatim punctato, valde quadrifoveato, postice versus medium strigis 
eleyatis haud connexis, elytris granulatis, fortius marginatis, parallelis postice angustatis et 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. retifer, latiuscula, depressa, nigro-zenea, thorace latitudine duplo breviore, antrorsum anegustiore, la- 
teribus late rotundatis, angulis posticis obtusis, fortius reticulatim punctato, obsolete quadrifoveato, elytris granu- 
latis, fortius marginatis, parallelis, postice angustatis et rotundatis. Long. -22. 
One specimen with the preceding. Differs from A.im perfecta by the faint fovex 
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. ex pansa and foveicollis, and
