EuciRRUS, Dvpont. 

 Eucirrus Griffithii, Hope. 



Obscure testaceus, thorace cinereo, elytris fere glabris ; sub 

 lente forte sparsim punctulatis. Corpus pedesque albo-squa- 

 , mosa. 



Caput fuscum, postice auratis capillis obsitum ; clypeo subre- 

 flexo, subemarginato. Thorax obscurus, cinereo-squamosus, 

 lateribus ovatis. Elytra obscure testacea, sub lente sparsim 

 punctulata, albis capillis e medio punctorum surgentibus. 

 Nodus albidus pilorum, fere apicalis, in singulo positus. 

 Anus fere trigonus cinereo-squamosus. Corpus infra fuscum, 

 pedibus concoloribus, albo-squamosis. 



Long, lin. 24, lat. lin. 12. 



Habitat in Assam. 



This is the largest Melolonthideous insect which has fallen under 

 my notice, being two inches in length. The type of the genus is 

 Eucirrus Mellii, the characters of which will be found detailed in 

 Guerin's Magasin de Zoologie, published in 1832. 



It must be remarked that the third joint of the palpi is not so 

 long as in the typical species. Instead of forming a sub-genus, 

 I retain Guerin's original name, as it cannot be ranged with Mr. 

 Kirby's genera Lepidiota or Holotrichia, both of them covered 

 with granulated scales. In the form and smoothness of its elytra, 

 and in the prominent tubercle of white hair placed near the apex 

 of the elyti-a, the above insect agrees with Lepidiota. I have 

 named it in honour of Mr. Griffitli, an indefatigable Botanist, who 

 captured it with other specimens in the Assamese territories. It 

 is, I believe, only the second species of Eucirrus yet described ; 

 a third, if I am not mistaken, is in the Vigorsian collection, now 

 in the possession of the Zoological Society.
