ADELOCERA Latr. 



A. pyrsolepis, castanea, confertim punctata, squamis fulvis dense tecta, 

 paucis nigris intermixtis, tliorace latitudine baud longiore, antice angustato, 

 lateribns ante medium rotundatis, angulis posticis parvis, divergentibus, haud 

 carinatis, medio late canaliculato ; elytris dorso depressis, puuctis nigris mar- 

 moratis ; subtus, antennis pedibusque fuscis. Long. 13 mm. 



New Mexico ; one specimen from New Mexico in Mr. Ulke's collection. 

 Allied to A. rorulenta Lee, but differs by the more robust form, brown 

 color, more dense golden fulvous scales, and by the less elongate thorax 

 having the hind angles divergent. It agrees nearly with the description of 

 the European A. le p ido pter a, as given by Candcze (Elat. i. 52), except 

 that there is no impression each side of the dorsal channel of the thorax. 



A. mac u lata, nigra, supra nigro-squamosa, confertim punctata, uiacu- 

 lis pallide aureo squamosis ornata, thorace latitudine longiore, convexo, 

 antice angustato, lateribus parallelis antice rotundatis, angulis posticis rectis 

 planis, haud divergentibus ; elytris extrorsum obsolete striatis, dorso vix 

 depressis ; subtus pallide squamosa, antennis pedibusque fuscis. Long. 

 13 mm. 



One specimen found near Philadelphia, by J. Johnson Brown, Esq., and 

 another at Washington, D. C, by Mr. Ulke. Related to A. a vita, but differs 

 by the pale scales not being uniformly diffused, but aggregated into spots. 

 The thorax is scarcely channeled, and is ornamented with four discoidal 

 patches of pale golden scales ; the sides, and to a less extent the apex, are 

 sprinkled with similar scales. The elytra are slightly depressed towards the 

 suture, and are feebly striate towards the base and sides ; there are small 

 scattered patches of pale golden scales, and two spots placed near the sides at 

 three-fourths of the length of the elytra, forming an oblique sinuous short 

 fascia; another spot is seen on the side near the apex. The front is not con- 

 cave ; the antennae are fuscous, and extend to about the middle of the thorax. 

 The feet are fuscous, and the tarsal grooves of the under surface of the pro- 

 thorax are distinct, though not well defined. The under surface of the body 

 is uniformly though not densely clothed with pale scales.

CRYPTOHYPNUS Esch. 



C. quadripustulatus Genu., Zeitsch. Eat., v. 142; Cande'ze, Mon. 

 EL, iii. 76. Elater quadr. Fabr., Syst. El., ii. 248. 



Specimens which agree with the descriptions of this European species were 

 found by Mr. Ulke at Washington ; they all belong to the variety in which 

 only the humeral spot of the elytra is present. The resemblance in form to a 

 small Cardiophorus, mentioned by Candeze, is very striking. 



C. gen til is, niger, pube brevi subtili flavo-cinerea vestitus, thorace 

 confertim subtiliter punctato, linea dorsali vix conspicua, latitudine vix 

 breviore, a medio antrorsum angustato, et lateribus rotundato, angulis posti- 

 cis acutis, haud divaricatis, breviter carinatis, apice testaceis ; elytris striatis, 

 interstitiis convexis, dense punctulatis, utrinque maculis duabus flavis orna- 

 tis ; sutura postice, epipleuris, tibiis tarsisque testaceis ; femoribus antennis- 

 que piceis, his articulo 3io 2ndo paulo longiore. Long. 3 - 5 mm. 



Nebraska; two specimens were received by Mr. Ulke, one of which he has 

 kindly placed in my collection. In the male the thorax is a little wider just 

 in front of the base, so that the hind angles appear somewhat divergent, and 

 the antenna? are slightly longer than in the female. The anterior elytral spot
