678 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Antennae large and well developed, compared with those of Dicerca and Chryao- 

 bothris; 3-joiuted; the basal joint membranons, third joint nearly as long as the 

 second, and blunt at tip. Labrnm rounded on the edge, fuller than in Dicerca. 

 Maxilla large and well developed ; maxillary lobe smaller in proportion to the base 

 of the maxilla than iu Dicerca or Chrysobothris. Palpus two-jointed; basal joint 

 much larger than the maxillary lobe (in Dicerca and Chrysobothris it is much 

 smaller) ; second joint one-fourth as large as first, being proportionally much smaller 

 than in the above mentioned genera. Labium much as in the said genera, being 

 rounded in front. 



Total length of body, 41"""; length of prothorax, 5™""; breadth, 8"""; length of 

 the three thoracic segments together, 8""" ; breadth of fourth abdominal segment, 4'"'". 



The hairs on the body are much coarser than in the other genera mentioned. 



This larva may be distinguished by the large head, the well-developed antennae, 

 the large maxillsB, with the lower joint of maxillary palpus small ; by the very coarse 

 and linear markings ou the prothoracic disk above and beneath ; by the absence of 

 Toughened areas or callosities on the meso- and metathoracic segments, and by the 

 long, thick abdomen. 



The mesothoracic segment is shorter and the metathoracic is as long as in Dicerca. 



4. The lesser Chalcophoua. 



Chalcophora liberta Germar. 



Very similar to the Virginian Buprestia, but alwaj's smaller sized, measuring from 

 0.75 to 0.90 in length, with the second raised line of the wing-covers broader than the 

 first or inner line, and totally obliterated where it is crossed by the posterior impressed 

 spot, its middle portion between the two impressed spots usually showing a few 

 scattered punctures. (Fitch.) 



" This species is much more common in eastern New York tban the 

 Virginian Bui)restis, the beetles appearing upon the leaves of pines 

 throughout the summer and autumn. From a small grove of young 

 pines only a few rods in extent upwards of a hundred specimens were 

 taken the middle of last September, one or two being found upon 

 almost every tree and bush; whilst only four individuals of the pre- 

 ceding and two of the following species were found in company with 

 them. They had probably been bred in the numerous stumps of larger 

 trees which had been cut down the year before by the side of this grove. 

 They stationed themselves at the tips of the limbs, clinging to the leaves 

 with their feet, with their heads inwards, their position, shape, and 

 size giving them a close resemblance to the young aments or fruit 

 cones which were growing from the same points on several of the limbs ; 

 and they appeared to be eating the young buds, which are probably 

 the food on which all these beetles subsist after arriving at their per- 

 fect state." (Fitch.) This Buprestid is also found iu Maine, but after 

 several years' attempts we have not been able to clear up the habits of 

 either species of Chalcophora, or to detect the larviB. 



''Chalcophora liberta very closely resembles the last species in its 

 markings, and might readily be mistaken therefor by those not 

 familiar with both. It is smaller, however, being only from three- 

 quarters of an inch to an inch long and is somewhat different in color. 

 It is generally of a bright coppery- red, but varies greatly in this respect,
