FAMILY TENEBRIONIDAE 237 



pygidium and abdominal segments dark brown to black. Head 

 depressed, red-brown on front, very finely punctate. Prothorax 

 rather square, longer than wide, very finely punctate. Elytra 

 elongate, rather narrow, apex truncate ; disk rather convex ; 

 depressed at apex ; finely striate-punctate. Legs light yellow. 

 Length, 2.7 mm. to 3.1 mm. 



This insect is probably predaceous upon Poly- 

 graphus longifolia. I have taken the insect abundantly ," .

Gonocephalum depressum, Fabr. 



REFERENCE. Fabr. Eni. Syst. Suppl. p. 41 (1789). 



Habitat. Siwaliks and Terai forests of United Provinces ; Changa 

 Manga, Punjab. Probably common throughout Northern India, 



Trees Attacked. Sal (Shorca robusta) : Siwaliks and United Provinces 

 Terai forests ; Sissu (Dalbergia sissoo) : Changa Manga. 



Beetle. Small, flat, ovate-elliptical. Greyish brown or rusty black. Head depressed in 

 front, eyes placed laterally and posteriorly, the antennae inserted in front of them ; punctate. 



Prothorax much wider than long, the anterior margin concave, sides 



Description. much rounded ; disk moderately convex, punctate ; elytra wider in 



apical fourth, thence constricting to apex ; apices conjointly rounded ; 



finely striate-punctate. Legs rather short ; antennae with the terminal joints knobbed. 

 Length, 6 mm. to 6.5 mm. 



This is a very common beetle, found in large numbers on the bark or 



stumps of sal-trees. It apparently breeds in dead and

importance. I have also taken it plentifully beneath 



the bark of sissu trees at Changa Manga. 



Gonocephalum elongatum, Guer. 



REFERENCE. Guer. Mag. Zool. 1837, Milas, p. .5-'. 



Habitat. Common in the plains of Northern India. 

 Tree Attacked. Breeds in the decaying wood and bark of a variety of 

 species of trees. 



Beetle. Resembles depression, but is narrower, the elytra markedly wider than pro 

 thorax, the eyes being situated higher up on head ; sides of thorax are rimed aniei loHy and 



straight behind : thorax is slightly tuberculate. Klylia i.ulually

This is another very common species of Gonocephalum, and is to be 

 found in the beetle stage almost throughout the year. It is found com- 

 monly in the forests, but is probably of small economic importance.
