transverse row of punctures, armed with^ long golden hairs, 

 the mandibles minutely punctured on their basal half. Palpi 

 and antennae honey-yellow, verging on rufous, the antennae 

 three-fourths as long as the body, with joint 4 fully one-half 

 longer than joint 3. Thorax finely and confluently punc- 

 tured, about as long as wide, rather wider behind than before, 

 the sides in a convex circular arc of not quite 6o°, the males 

 with the thorax rather longer and laterally less strongly 

 curved than the females. Elytra punctato-striate, the stria 

 sub-obsolete, the punctures approximate, and rather large but 

 not deep, the interstices flat and with close-set, fine, shallow 

 punctures. Legs with the anterior tibiae of the male sud- 

 denly crooked three-fourths of the way to their tip ; anterior 

 tibiae of the female as straight as the others. Length of male, 

 .24-. 27 inch; female, .24-. 28 inch. 



Larva: C. Fig, 1, PI. IX. Length, 8. to 10. mm. Color; 

 body white, head and cervical shield honey-yellow, clouded 

 with white, mandibles and clypeus darker, with the tips of 

 the former and the prominent clypeal suture nearly black ; 

 spiracles and claws brownish-yellow, the former and anterior 

 pair of feet sometimes darker. Head considerably smaller 

 than first thoracic segment, which is a little smaller than the 

 second ; third equal, from which the body tapes slightly and 

 regular^ to twelfth ; thirteenth smaller, orbicular and almost 

 rudimentary, containing the vent, the latter forming depres- 

 sions in the form of the letter Y, and dividing the area into 

 three elevated spaces, on each of which are situated a number 

 of short, decumbent spines, pointing inward, and on the 

 spaces between the two branches of the Y are two larger 

 spines, both of which are erect ; there are also groups of 

 shorter spines on the twelfth segment, and with two longer 

 spines, likewise occupy elevated areas : on the ventral surface 

 of all the segments, except the thirteenth and thoracic, are 

 many short, reddish, ambulatory setae ; above, there is a single 

 transverse row of short bristles emanating from small pus- 

 tules, which are more conspicuous posteriorly. The first 

 spiracle is located between the second and third segments, 

 and is frequently a little more distinct than the others which 

 are located on each segment, from fourth to eleventh, inclu- 

 sive. On the head, a, Fig. 1, PI. IX, the clypeal suture is
