360 MEMOIRS ON THE COLEOPTERA 



This is the largest Bostrychid known thus far within our geographic 

 limits, excepting Dinapate wrighti Horn. It is not closely related 

 tofortis Lee., from Cape San Lucas, or to robustus Csy., from Texas; 

 puncticeps differs greatly from the other three in the close and 

 rather strong punctures of the head. The above measurement does 

 not include the thoracic processes, which are about I mm. in length. 



BUPRESTID^: 



A number of new forms in this family seem worthy of description 

 as follows: 



Chalcophora ingens n. sp. Large and stout, unusually convex, 

 strongly shining, blackish, the under surface and finely, closely punctate 

 impressions of the upper surface cupreous; general facies and sculpture 

 of the elytra as in virginiensis, the head larger, with very deep sulcus, 

 the antennae notably longer, extending to basal third or fourth of the 

 prothorax, the latter similar in general form but having the sharply 

 marked obtuse lateral angles but little before the middle; elytra more 

 convex, much more sloping posteriorly from near the middle of the 

 length, the serratures of the sides posteriorly very feeble; under surface 

 nearly similar, the two fine grooves of the prosternum more rapidly 

 converging posteriorly. Length (9) 31.5 mm.; width n.o mm. 



A single example, unfortunately without indication of locality. 



Chalcophora virginiensis ssp. antennalis nov. Similar to virginiensis 

 in general form, coloration and sculpture, but with a notably larger head 

 and longer, more slender antennse, which extend almost to the base of the 

 prothorax, the latter similar in general form and with the sides obtusely 

 and arcuately subprominent near apical third, but with the intricate 

 sculpture toward the sides more broken; elytra similar but with the sides 

 more rounded inward at base and the embossed smooth surfaces less 

 elevated; sides distinctly serrulate apically; under surface nearly similar, 

 except that the metasternum is more broadly concave. Length (9) 

 29.0 mm.; width 10.0 mm. Idaho. 



This form is distinguishable at once from virginiensis by its larger 

 size, rather broader form, larger head and longer antennae; it is 

 probably more nearly specific in value than subspecific. 



Chalcophora cupreola n. sp. Form and habitus nearly as in lauren- 

 tica and fortis, but brighter aeneo-cupreous in color, with still finer longi- 

 tudinal elevations of the elytra and a much smaller head; elytra near the 

 humeri and along the epipleura metallic greenish; under surface bright 

 cupreous throughout; head barely half as wide as the prothorax; vertex 

 nearly as in laurentica, the median groove less deep, the sparse pubescence 

 rather longer; eyes much less convex, separated by barely more than 

 twice their width, viewed vertically; antennae short, black, the two basal
