ently a female, and the antennae do not pass the hind angles of the 

 thorax; they are very likely longer in the male, in which also the 

 sides of the thorax may prove to be less strongly rounded. 



A€.M^£ODERA. 



A. bowditclii sp. nov ^-Moderately robust, not strongly depressed, piceons 

 bronzed. Thorax with or without a small lateral yellow spot at basal third. 

 Elytra with four more or less irregular transverse rows of yellow spots, which 

 have a tendency to become confluent, especially toward the apex. Head densely 

 punctate, vertical carina feeble. Thorax twice as wide as long, very slightly 

 dilated before the hind angles, rather feebly narrowed in front, lateral margin 

 not visible from above, discal impressions moderate, punctuation dense and 

 moderately coarse at sides, less close and somewhat finer toward the middle. 

 Elytra feebly narrowed to apical third, thence more rapidly to apex; sculpture 

 about as nsual. Prosternum slightly retracted, front margin nearly straight. 

 Abdomen rather coarsely and closely punctate, especially toward the apex ; api- 

 cal plate large, truncate or broadly rounded, the free edge thin and even. 

 Length 8-9 mm. 



Hah. — Southeastern California ; Arizona (Prescott). 



At the time of my Revision of Acmceodera I possessed a single 

 specimen of this species, which I was then unwilling to define, but 

 which was set apart as being probably distinct. Since then, through 

 the kindness of Mr. Frederick Blanchard, I have received several 

 examples from Prescott, Arizona, these being a part of a considera- 

 ble series collected some years ago by Mr. H. K. Burrison and sent 

 by him to ^[r. F. C. Bowditch of Boston. The species is dedicated 

 with pleasure to friend Bowditch, to whom we are indebted for its 

 distribution. Bowditchi belongs to the Group Emarginatte, and 

 would stand between flavosticta and acuta in the table of the Group. 

 As compared with flavosticta it is less depressed, less pointed behind, 

 the thorax less transverse, the elytral spots more numerous and the 

 abdominal punctuation coarser. As compared with ac\da, the elytra 

 are somewhat more coarsely sculptured, the fifth interspace is dis- 

 tinctly more convex toward the base, the elytral spots are larger and 

 more constant, the abdominal sculpture coarser and the apical plate 

 wider. The markings are much like those in some specimens of 

 variegata, which species is, however, somewhat more depressed, with 

 much more finely punctured abdomen and no apical plate. 



A. liicia sp. nov. — Closely related to pulchella and obtiisa, between which it 

 should be placed. The sides of the thorax are slightly but unmistakably re- 

 tracted behind, instead of being convergent from the base as in pulchella; the 

 lateral margin is still more inferior ; the thoracic punctuation more shallow and
