LAMELLICOENIA. 411 



Chrysina amoena (p. 286). 



The female example from Ciudad in Durango belongs to the following species, and 

 the locality should therefore be erased. 



3. Chrysina erubescens. (Tab. XXIV. fig. 23, $ .) 



C. amcena affinissima, sed differt corpore paullo majore coloribusque diversis. Supra pallide pomaceo-viridis. 

 fronte et clypeo erubescentibus, scutello thoracisque lateribus leviter rosaceis ; subtus differt pectore 

 obscure seneo ventroque dimidio basali argenteo-seneo politissimo dimidio apicali rufo-seneo minus nitido, 

 femoribus tibiisque rufo-testaceis, politis, submetallicis, tibiis apice caerulescentibus, tarsis cyaneis ; pygidio 

 lastius carnescenti-lateritio, dense punctulato linea dorsali lsevi. Supra sicut in G. amoena dense hie illic 

 rugulose punctulatis punctis minutis intermixtis. J • Pedes postici parum elongati sed femoribus incras- 

 satis, tibiis rectis latis intus basi subito profunde emarginatis, dentatis.

Hab. Mexico, Ciudad in Durango (Edge), Durango city (Becker), Sierra de Nayarit 

 (Bi chard son). 



Three examples, a male and two females. Our figure is taken from a female 

 from Ciudad. 



4. Chrysina beckeri. 



O. amcena', proxime affinis et simillima. Differt colore supra cum pygidio paullo dilutius pomaceo-viridi 

 leviter metallico, subtus fulvescenti-viridi pedibusque fuscescenti-camileis, tarsis chalybeis. Supra 

 nitidior, sparsius punctulata, interstitiis punctorum absque punctulis minoribus, elytrisque disco sub- 

 seriatim punctulatis. c? • Pedes postici crassiores haud longiores, prascipue femoribus dilatato-compressis ; 

 trochanteribus apice haud prolongatis.

Hah. Mexico, Canelas in the Sierra Madre de Durango (Becker). 



A pair of this species has been sent me by Mr. Flohr, who points out its close 

 affinity with C. amcena. It differs from C. amcena in the sparser punctuation of the 

 upper surface, in which character it is intermediate between C. amoena and the more 

 strongly punctured examples of G. macrojms. It agrees with C. amcena in the pro- 

 minent, though small, mesosternal process, which is narrower and more acute, though 

 much stouter than in C. erubescens. 



I have named it, at Mr. Flohr's request, after the discoverer, Mr. Richard Becker of 

 Durango, who is exploring with great success the Coleopterous treasures of the 

 interesting region near which he resides.
