Statira apparently replaces Lagria in the New World ; and its species are still more 
fragile. ‘The North-American genus Arthromacra and the Tropical-South-American 
genera Emydodes, Barsenis, and Disema are not represented within the limits of our 
fauna*. Two other genera from Tropical South America have been referred to the 
Lagriide: one of these, Storthephora, Makl., is congeneric with Paratenetus, Spin. 
(cf. Biol. Centr. -Amer., Col. iv. pt. 1, p. 238), a genus considered by recent authors to 
belong to the Group ‘ Hetsiotanides’ of the Tenebrionide, the author including in it 
two species of small size (one from Venezuela and one from Brazil)}; the other, 
Acropachia, Makl., doubtless belongs to the same group. 
Very many Central-American species of Lagriide closely resemble those of widely 
separated families; one genus, Uroplatopsis, has quite the facies of certain genera of 
Hispide, and some of its species (all of which are apparently very rare) possess very 
remarkable sexual characters. So far as we have been able to ascertain, the secondary 
sexual organs of the male do not afford (except in some few species) good corroborative 
specific characters. 
* During the past month two additional genera from South America have been described by Fairmaire 
(Compt. Rend. Ann. Soc. Ent. Belg. xxxiii. p. xlix): one of these, Stpolisia, agrees in many of its characters 
with Disema. 
+ These are closely allied to P. denticulatus (cf. Biol. Centr.-Am., Col. iv. pt. 1, p. 243, t. 10, fig. 26).
