232 THE CANADIAN ENTOMOLOGIST 



some specimens of Dicerca tiiherculata. My single specimen of this species is a 

 bronze colour very similar to the dark forms of Biiprestis striata, and is probably 

 very near to the form lateralis Casey. The costae are a greenish black, and the 

 punctures along the stride are a bright green set in the bright coppery rugae of 

 the intervals; it lacks the greenish shading of the type on the under side. , 



Chrysobothris orono, n. sp. Size and form of verdigripennis: Black 

 with the punctured areas of a grayish-green colour, beneath cupreous or bronzed 

 with the prosternum, femora, and sutures of the abdomen greenish. Antennae 

 bright metallic green, last joint and the lobes of the preceding seven, black. 

 Clypeus arcuately emarginate with sides rounded, front greenish, coarsely, 

 densely punctured and pubescent with two small median callosities; eyes rather 

 widely separated above. 



Prothorax not quite twice as wide as long,. slightly wider at base than at 

 middle, briefly rounded and narrowed at apex, slightly sinuate at middle, and 

 with a very small sinuation before the hind angles, which are rectangularly 

 acute and not narrowed ; median dorsal sulcus limited in front by strong angulate 

 costse, which broaden out at middle and disappear behind; a short sinuate cal- 

 losity at middle on each side.

Elytra widest behind and sinuate in front of middle, more convex than 

 scabripennis , sutural costae entire from apex to basal fourth and more strongly 

 elevated than any of the others which are indicated by flattened, smooth, black 

 areas and lines, punctured areas not as well defined as in scabripennis and verdi- 

 gripennis, basal foveae less evident. 



Abdomen with sparse, shallow punctures and indistinct callosities, last 

 ventral body semicircularly emarginate, last dorsal coarsely, sparsely punctured 

 with a small, indistinct notch; prosternum not lobed, very densely pubescent 

 and punctate, sides with coarse, sparse punctures and broad, interlacing, smooth 

 spaces, the dense white pubescence extends along the median line on to the 

 metasternum gradually becoming more sparse; front femora with a strong, 

 serrulate, acute tooth; tibiae with a large apical dilatation nearly one-third the 

 length of the tibia, sinuate at the distal end, rising in an arc and terminating 

 rather abruptly without sinuation; front and middle tibiae strongly arcuate, 

 hind tibiae straight. 



Length 14.5 mm., width 6 mm. at apical third. 



The unique type is a male from Orono, Maine, July 4, 1908, in my collec- 

 tion. The species is dedicated to the Indian chief Orono, from whom the town 

 where it was taken is named. 



The species most nearly resembles verdigripennis superficially, but is dis- 

 tinct by the dark antennal joints, the much different tibial dilatation, and the 

 straight hind tibiae. In the coloration of the dorsal surface and in the tibial 

 dilatation it resembles carinipennis, but in no other respects. From trinervia 

 it differs in the shape of the thorax, tibial dilatation, elytral sculpture, size and 

 last dorsal segment of abdomen.
