11. Hetrodes fortis. 



Mas. Testaceua, fiixco nebxdosus ; caput nnispinosum, vertice scahro ; 

 prolhorax svaber, quadrispinosus corniibusque duobus trispinosis 

 armaiiim, postice Iridecim spinosus, Lateribus paltide testaceis ; abdo- 

 men Iriseriatim spinosum ; tibia bispinosce. 



Male. Testaceous, partly tinged with brown. Head above and pro- 

 thorax scabrous. Head with a rather long slightly ascending spine between 

 the antennae. Fore part of the prothorax with a directly diverging spine 

 on each side hiudward, with two spines on the fore border, which on 

 each side has a long protuberance armed with three spines; hind part 

 with three sj)iues on the hind border and with six on each side; four of the 

 lateral spines long; sides pale testaceous, blightly reflexed. Abdomen with 

 three dorsal rows of spines. Legs long; femora without spines; tibiae with 

 two spines beneath. Length of the body 15 lines. 



It is much allied to H. militaris ; the two typical specimens of the 

 latter appear to be in an early stage of growth. It is distinguished from 

 H. cen^inus by the two red snipes on the abdomen, by the fewer spines on 

 the hind part of the prothorax, and by the hind tibiae, which have no spines 

 above.

12. Hetrodes vittatus. 



Alas. Testaceus ; caput scabrum, unispinosum, fronte nigricanle ; pro- 

 thorax scaber, antics decimspinosus nigro quadrivitlaius cornubus 

 duobus trispinosis armatus, postice octospinosus ; abdomen sexseriatim 

 spinosum, nigro trivittatum ; pedes robusti, breviusculi, tibiis quatuor 

 anterioribus trispinosis, tibiis posticis quinquespinosis. 



Male. Testaceous. Head and prolhorax scabrous. Head with a 

 porrect acute rather long spine between the eyes; front mostly blackish. 

 Prothorax with the usual transverse middle furrow; fore part with six 

 obtuse spines in the disk, with a spine on each side, with two spines on the 

 fore border, where there are also two exterior obliquely diverging horns, 

 each armed with three spines; four black stripes, the inner pair very 

 slender, the outer pair very broad ; hind part with eight marginal si)ines. 

 Abdomen with six rows of spines and with three black stripes, ihe outer 

 pair irregular. Legs stout, rather short; femora without spines; tibiae 

 with three spines beneath; hind libiag with two spines above. Length of 

 the body 12 — 14 lines. 



The striped body will distinguish it from the preceding species of this 

 group. The shorter legs will distinguish it from H. fortis and from 

 //. militaris, and the spine on the head is longer than that of H. Petersii,
