ii2 FAMILY COLYDIIDAE 



jointed, yellow at base, last joint black. Ventral surface yellow, edged with 

 black on segments two to eleven inclusive. The twelfth segment is pro- 

 vided with an abdominal sucker leg ; the upper functional part divided into 

 two surfaces. 



I endeavoured to rear the beetle from this grub, but failed. 



I have taken colydiid beetles in a number of forest trees throughout the 

 country, amongst which may be mentioned most of the conifers and oaks of 

 the Western Himalaya, and the sal, teak, pyinkadu, Anogeissus, Lager - 

 stromia, Erythrina, Dalbergia, Wendlandia, Morns, Buchanania, etc. 



BOTHRIDERES. 



Species of this genus are known to be predaceous upon bark- and wood- 

 boring beetles in trees. 



Bothrideres andrewesi, Grouv. 



REFERENCES. Stebbing, Depart. Notes, p. 21 (1902). 



Habitat. Changa Manga, Punjab. 



Habits. This beetle is predaceous upon the wood-borers Sinoxylon 

 crassnm and S. anale. It is a fairly common insect in the galleries of the 

 borers in sissu at the Changa Manga Plantation near Lahore (vide p. 165). 



Bothrideres vallatus, Grouv. 



Habitat. Siwaliks, North India. 



Habits. Specimens of this beetle were taken from under the bark of a 

 dead Lagerstromia parviftora tree and from tunnels in the cambium layer of 

 a newly felled dead Erythrina suberosa. The beetles were taken by Student 

 B. C. Sen Gupta in the middle of February 1902 at Bulawala in the Dun 

 forests. 



I also took specimens of this or a closely allied species of Bothrideres 

 from beneath the bark of sal-trees at Dholkhand in the Siwaliks in 

 January 1902. 



Bothrideres ? sp. 



Habitat. Goalpara, Assam. 



Habits. I bred out a specimen of this beetle from a pupa taken from a 

 partially complete pupal chamber of Hoplocerambyx spinicornis in sal, in 

 Goalpara, in 1906. The shrivelled skin of the cerambycid grub lay in the 

 chamber beside the colydiid beetle (vide p. 334).
