284 Mr. H. W. Bates on the Longicorn Coleoptera 



The above description applies to a species which I have seen 

 in collections at Paris under the name of A. arachnoides of 

 Serville, and to which the description of Serville applies, as far 

 as it goes. I found it on the same trees with A. phalangodes 

 at Ega, and also met with it at Para. 



3. Anisopodus cognatus, n. sp. 



A. subellipticus, carneo-griseus, sericeus, nigro punctatus : thoracis 

 spinis lateralibus unciformibus : elytris absque tuberculis centro- 

 basalibus, apice breviter mucronatis, pone medium macula lateral! 

 nigra obliqua notatis : pedibus posticis maris elongatis, fortiter 

 clavatis. Long. 4 lin. 



Head brownish. Antennae pitchy red, tips of the joints dusky. 

 Thorax greyish, fore part of the disk with tw^o black spots, 

 punctured ; the lateral spines pointing to the hind angles, their 

 anterior sides (nearest the head) being continuous with the lateral 

 outline of the thorax, and therefore giving them a hooked shape. 

 Elytra sinuate-truncate at the apex, both angles of the trunca- 

 tion pointed, but neither prolonged into a spine ; the surface is 

 grey with a pinkish shade, irregularly spotted wdth blackish, and 

 having each, behind the middle, an oblique spot or fascia ex- 

 tending from the side to the middle ; the deflexed margins are 

 of a light silky-brown hue, like the under surface of the body. 

 Legs dusky, base of thighs and tarsi pale testaceous. The hind 

 legs of the male considerably elongated ; the thighs in both 

 sexes abruptly clavate. 



Ega and S. Paulo, Upper Amazons, in the same situations as, 

 and sometimes in company with A. phalangodes . 



4. Anisopodus sparsus, n. sp. 



A. subellipticus, carneo-griseus, sericeus, nigro punctatus : thoracis 

 spinis lateralibus brevissirais, antice a lateribus vix distinctis : 

 elytris apice oblique sinuato-truncatis, angulis vix productis, absque 

 tuberculis centrobasalibus, pone medium atro-fusco fasciatis. 

 Long. 4^-5^ lia. 



Head greyish silky. Antennae reddish, tips of joints dusky. 

 Thorax pinkish grey, punctured, bimaculate ; lateral spines on, 

 their anterior sides scarcely distinct from the sides of the thorax, 

 their minute points only being directed outwards ; they have, 

 therefore, not the hook-like shape of those of A. cognafus. 

 Elytra wath the angles of their truncation scarcely produced ; 

 their surface is grey, with a pinkish tinge, finely spotted with 

 blackish, and with a largish black spot marking the site of the 

 centro- basal tubercles (which are quite absent), besides an angled 

 fascia of the same hue crossing behind the middle. The deflexed 

 sides and under surface of the body are light brown and silky.
