pygidium and abdominal segments dark brown to black. Head 

 depressed, red-brown on front, very finely punctate. I'rotliorax 

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

 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 ,„j^ 



in the galleries of this beetle in Pinus longifolia in Fic. 162A.

GONOCEPHALUM. 



Gonocephalum depressum, Fabr. 



Reference. — Fabr. Ent. 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 sissuo) : Changa Manga. 



Beetle.— Small, flat, o\ate-elliptical. Greyish brown or rusty black. Head depressed in 



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



I'rothorax much wider than long, the anterior margin concave, sides 



Description. much rounded ; disk moderately conx'ex, punctate ; elytra wider in 



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



tinelv striate-punctate. Legs rather short : antennae with the terminal joints knobbed. 



Length, 6 mm. to 6.5 mm. 



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



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



Life History. decaying wood, and is probably of small economic 



importance. I have also taken it plentifully beneath 



the bark of sissu trees at Changa Manga. 



Gonocephalum elongatum, Guer. 



Referenxe.— Guer. Mag. Zool. 1S37, Milas, p. 32. 



Habitat. — Common in the plains of Northern India- 

 Tree Attacked. — Breeds in the deca\ing wood and bark of a variety of 

 species of trees. 



Beetle.— Resembles depression, but is narroxser, the elytra markedly wider than pro- 

 thorax, the eyes being situated higher up on head ; sides of thorax are curved anteriorly and 

 straight behind ; thorax is slightly tuberculate. Elytra gradually 

 Description. widen from base apically, constricting on a uniform curve at apex ; 



punctate-striate, the striae rather far apart. Knobs on antennae not 

 so prominent. Length, 8.2 mm. 



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.
