480 CLASS VIII. 



between the mandibles. Maxillge with only one lobe or with two, 

 internal very small ; mandibles strong, especially in males. Thorax 

 not separated from head by constriction anteriorly. 



A. Antennce longer than head and tJiorax together. 



Prionus GEOFFR. FABR. Body depressed. Thorax with sides 

 acute, often dentate or spinose. Antennae in some pectinate or 

 serrate, in others simple, attenuated towards the extremity. Man- 

 dibles of males sometimes exsert, long. 



Sp. Prionus coriarius FABR., Cerambyx coriarius L., ECESEL Ins. n, Scarab. 

 terr. 01. n. Tab. i. figs, i, 2, Tab. n., PANZER Deutschl. Ins. Heft 3, Tab. 

 9 ; in Germany and other parts of Europe. 



To this genus belong some gigantic exotic species, e.g. Prionus cervicornis, 

 Cerambyx cervicornis L., EXESEL Ins. n, Scar. terr. Cl. 11, Tab. i, fig. B ; 

 VOET. Coleopt. n, Tab. n, figs. 4, 5 ; Cuv. It. Ani. ed. ill., Ins. PI. 64, 

 fig. 3, from South America. Prionus Hayesii DOWNES, HOPE Transac. of 

 the Zool. Soc. I, PI. 1 6, from the west coast of Africa near the Equator. 



Some species, with short narrowed elytra, which occur in South America, 

 form the genus Anacolus of LATREILLE ; other species, also from South 

 America, have besides no wings (Prionapterus GU 



B. Antennce short (of the length of thorax). Head of the same breadth as 

 thorax. Thorax unarmed. 



Spondylis FABR. Ligula membranous, cordate. Thorax glo- 

 bose. Body convex. 



Sp. Spondylis buprestoides FABR., Attelabus buprestoides L., DUMERIL Cons. 

 gen. s. L Ins. PI. 17, fig. 6 ; EA.TZEBURG Forst-Ins. I. Tab. xvn. fig. 12. 



Parandra LATR. Ligula horny, lunate, transverse. Third joint 

 of tarsus scarcely bifid, last longer than the rest taken together. 



Sp. Sparanda brevis LATR., Gen. Crustac. et Ins. Tab. 9, fig. 7 ; Parandra 

 glabra GYLLENH., Attelabus glaber DE GEER Ins. iv. Tab. 19, figs. 1416, 

 Scarites testaceus FABR. The fourth joint of the tarsus is here more appa- 

 rent than in the other Pseudotetramera, so that some count this genus 

 amongst the Pentamera. 



The habitus of these insects resembles that of LUCANUS. LATREILLE 

 first placed this genus in the neighbourhood of Cucujus (Hist. nat. det 

 Crust, et des Ins. Tom. XI. p. 252) and from later writers also it received 

 the same place ; the affinity however with Spondylis seems to assign tc 

 Parandra a place amongst the Prionidce. 



Family L. Scolytaria (Scolytidce WESTW., Xylophagi LATR. 

 in part). Third joint of tarsus in some bilobed, in others entire
