COLEOPTERA. 
Cossyphodinus indicus, Wassman, lives with Pheidole sulcaticeps , Rog.. 
and is the sole recorded Indian species. (Fig. 153). 
Colydiidas. 
Antennce clubbed or dilated towards the apex. Tarsi four-jointed ; 
five visible ventral segments. 
These are small beetles of varied form found under bark in decay¬ 
ing trees or in fungi. They are not common and but few species are 
known from India. Tarphiosoma indicum , 
Wal.. is described from Coimbatore. 
Dastarcus and Colobicus are also re¬ 
presented. Botrideres is, in Europe 
known to be predaceous on the larvae of 
the Bostrichid beetle, Sinoxylon , which 
bores in wood, and Stebbing records 
the same in India. A total of 17 species 
are recorded, Dastarcus indicus , Fairm., 
being common under the bark of trees 
in the plains. 
Lathridiim. 
Tarsi three-jointed ; antennce with a club formed of one , two or three 
joints. Ventral abdominal segments five or six, free , the first longest. 
Small beetles rarely more than one-tenth of an inch long, found in 
ants’ nests and in decaying vegetable matter, where it is supposed they 
eat fungi. None appear to have been reared in India. Wassman 
writes about Coluocera maderce, Wall, and C. Beloni, Wasm. Zeits. Wiss. 
Insecten Biol. I, p. 384) which live with Prenolepis longicornis and 
Pheidole spp. in India. Assmuth observed the former to move with 
the ants along their runs when shifting nests and Wassman comments 
on the fact that C. Maderce , like Myrmecophila prenolepidis, is found in 
the nests of this ant in South America as in India, the beetle and cricket 
having apparently been carried by shipping with the ant. 
Eighteen species are recorded in Genera Insectorum as Indian: 
Coluocera (1\ Holoparamecus (6), Lathridius (1), Ericmus (1), Cortica- 
ria (3), Melanophthalma (5), Migneauxia (1).
