Long. corp. 120-130, lat. pron. 17-20 mm. 

 Male. — Black ; head with two moderate-sized spines wide 

 apart, nearly hallway between the eyes and the occiput, and 

 two smaller ones, nearer together, rather further back ; pro- 

 notum with 2 large lateral spines in front and 1 behind ; 

 mesonotum with 7 or 8 strong lateral spines, the last some 

 distance behind the penultimate one and near the hinder 

 edge ; there are also less regular rows of smaller spines below 

 them and on the mesopleura ; metanotum and metapleura 

 with large irregular lateral spines, the largest being two about 

 the middle, and another above the hind coxa ; segments of 

 the abdomen (except the last) each with 3 strong lateral spines, 

 and with one or two terminal large tubercles at a higher level ; 

 segments 7-9 with a short terminal tooth on the median 

 line ; upper surface of the body except at the sides spinulose, 

 but with scattered granules ; coxas spined ; 4 first femora 

 thickened and with regular but rather widely separated teeth 

 on the carinas; 4 first tibiae with 4 or 5 moderately large 

 teeth on each side beneath ; hind femora greatly dilated, and 

 with 3 large teeth beneath, the last very large and curved 

 backwards ; there are also strong terminal spines on the 

 carinas beneath ; hind tibias with 3 large teeth beneath, the 

 middle one double, besides smaller ones towards the base and 

 on each side at the extremity. 



Female more ferruginous; the spines smaller, but similarly 

 arranged ; the hind femora are much less thickened, and the 

 third spine is not much larger than the others. 



Hob. New Britain. 



Nearest to E. calcarata, Luc, but much less strongly 

 spined. The true E. horrida, Boisd., differs from most of the 

 allied forms by the lateral spines on the abdominal segments 

 being smaller and more numerous. 



Eurycantha portentosa, sp. n. 



Long. corp. 170, lat. mesonoti 22-26 mm. 



Female. — Black ; antennas, legs, and under surface inclining 

 to ferruginous ; spines arranged nearly as in the last species ; 

 much more strongly granulated on the upper surface, and 

 with a transverse row of short spines before the extremity of 

 most of the abdominal segments. There are sometimes
