Order COLEOPTERA. 
Tribe LONGICORNIA. 
Fam, PRIONIDA. 
Subfam. PRIONIN A. 
In this subfamily are included the whole of Legions I. & II., and of the latter 
Cohortes I. & II. of Lacordaire’s system, resting the definition of the combined subdivi- 
sions chiefly on the character of coarsely-faceted eyes. The highly artificial separation 
of diverse abnormal forms as a “Legion” equivalent to a natural group of the same 
rank, as proposed by Lacordaire, is here avoided. The character of coarsely-faceted 
eyes, in Prionide as in other subfamilies of Longicornia, seems very generally asso- 
ciated with nocturnal habits and sombre colours. 
PARANDRA. 
Parandra, Latreille, Gen. Crust. et Ins. iii. p. 28 (1802). 
Thirty-five species of this aberrant Longicorn genus were recorded in the Munich 
Catalogue (Catalogus Coleopterorum, auctoribus Dr. Gemminger et B. de Harold) in 
1873; but many of these have since been shown to be slight varieties or synonyms. 
The general form (or facies), colour, and sculpture are remarkably similar in all; and 
unless close attention is paid to the dentition of the mandibles in the males and the 
accessories of the tarsal claw-joint, it is impossible to distinguish them with accuracy. 
Some twenty distinct species, however, are known ; and their distribution is remarkable: 
America (Tropical and North) is their metropolis, Western Tropical Africa, the Cape 
of Good Hope, the Moluccas, and New Caledonia having each one or two species ; and 
one isolated member is found on the borders of the Caspian.
