New Species of Macrogonus (Coleop.). 



By F. C. BOWDITCH, Boston, Mass. 



Two new species of Macrogonus should be added to the 

 list, one of which is from New Guinea and the largest yet 

 described ; types of both are in my collection. 



Macrogonus atripennis nov. sp. 



Rufous, head and thorax more or less aenescent the jaws, antennae, 

 except the first joint, the apex of the tibiae, the tarsi and elytra and 

 first four segments of the abdomen blue black. 



Head with a broad triangular depression in front, the rear angle 

 continued over the vertex in a well marked groove, surface finely and 

 rather regularly punctured, antennae reaching a little beyond the 

 middle of the body, pubescent (except the scope), 2nd joint short 

 tubular, 3d about one half longer and 4th distinctly longer than the 

 third, 5th, 6th and 7th longest of all ; thorax with the lateral middle 

 angle well developed, stout and acute, the four corners angulate, se- 

 tose, two well marked foveae, one on either side back of the middle, 

 basal depression elongate, well marked, the entire surface shining, 

 sparsely punctulate, rear rounded and faintly margined, elytra parallel, 

 shining, surface everywhere obsoletely wrinkled with about 10 rows 

 of very fine punctures, regularly placed becoming obsolete at the rear 

 and scattered punctures in the intervals, shoulders prominent, each 

 elytron with two deep foveae placed as usual in the genus, subbasal 

 median, and median sublateral ; the body below especially the dark 

 part is strongly punctate. 



Type Richmond River, New South Wales, 2 examples ; 

 length 10 mm. 



Very much resembles in color Macrolema longicornis Jac. 



Macrogonus aenescens nov. sp. 



Head rufous, aeneous, vertex dark metallic green, antennae reach- 

 ing below the middle of the body, five lower joints purple, remainder 

 dull, submetallic, all except the scope pubescent, thorax rufous, base 

 and middle suffused aeneous bronze, extreme basal edge purple, 

 scutel rufous iridescent, elytra polished, shining, bronzed, extreme 

 thickened edge touched with purple, body beneath and femora rufous, 

 with extreme tip of latter and tibiae and tarsi dark submetallic pur- 

 plish. Length 15 mm. 



Head has the labrum slightly darkened and with a broad triangular 

 depression on the front between the eyes (as in subinetallicus Jac.) 

 and a deep elongate fovea on the vertex, punctures thick near and be- 

 tween the eyes, becoming sparse at the top and rear of the vertex.
