G eiius. — M ALLOSOMA, Serville. 



This genus is closely allied to the preceding : Serville ('Ann. Soc. 

 Ent. of France,' iii. 68) has scarcely assigned it a single character by 

 which to distinguish it; he has indeed described the termination of 

 the elytra as unai'med, which is erroneous, the exterior angle of the 

 trimcature haAdng an obvious spine. A beautiful species, Mallosoma 

 elegans, is common in Brazil, and is found running over the trunks 

 and leaves of trees, and flying readily, after the manner of a Clytus, 

 close to which genus it has been placed by the Count Dejean. The 

 following sjaecies I think is not previously described. 



Mall, fuligineum. Fuligineum, obscurum, lanugine nigra dense 

 tectum : prothorax ferrugineus, macula magna rotundata dorsali 

 lineaque laterali nigris : elytra immaculata. (Corp. long. "5 uuc. 

 lat. "175 unc.) 



Inhabits Brazil. A single specimen is in the cabinet of the Ento- 

 mological Club. 



Genus. — Phacodes, Newman. 



Caput fere pronum : antenna3 graciles corpore paullo breviores, pi- 

 losre, 11 -articulatiB, articulis 3 — 5 apice 1-spinosis : prothorax fere 

 cylindraceus lateribus rotundatus inerniis, dorso tubeiibus tribus gla- 

 bris instructus : elytra ampla, convexa, apice rotundata, apice ipso 

 truncato, angulo exteriori l-s])inoso : pedes mediocres. 



Phac. lentiginosus. Facies Callidii : prothorax rugosus : elytra 

 pmicta, quoque pustulata; punctisbasim versus crebri ores: pus- 

 tuHs passim dispositis. Color iliscus, fascia pone medium valde 

 indistincta lanuginosa albida. (Corp. long. 1*2 unc. lat. "375 

 unc.) 



Inhabits New Holland. In the cabinet of the Entomological Club. 



This large and abundant insect seems to have been unknown to 

 Boisduval and MacLeay. Its appearance is that of a large Callidium ; 

 in some of its characters it displays an obvious affinity to the Phora- 

 canthidae.
