378 FAMILY CERAMBYCIDAE 



depth and about an inch in diameter, completely encircling branches of a 

 Tabcrnamontana alba tree in that locality. The specimens were sent to the 

 Indian Museum and identified subsequently by Mr. Gahan. The following 

 year the beetle was obtained by the Deputy Conservator of Forests, Coorg, 

 where he had found the beetle girdling and cutting down rose-trees. The 

 Deputy Conservator in his letter wrote: "These beetles cut off the stem 

 clean in one night. . . . Large rose-trees are thus cut down and destroyed. 

 . . . They attack the main stem and despise smaller branches." 



No further reports appear to have been made upon the life history of 

 this pest. It is one of that interesting class of insects, the girdling longi- 

 corns, the object of the beetle in girdling the stem or branch being to ensure 

 the slow death of the portion above the girdle in which she lays her eggs. 

 It thus affords a supply of fresh sappy bast and sapwood through which the 

 sap is no longer rising for the young larvae when they hatch out. The 

 grubs feed on this, and when full-grown, by which time the branch will 

 have dried considerably, they eat out a pupal chamber and change to 

 pupae. On maturing the beetle bores its way out of the stem or branch 

 and escapes. 



GLENEA. 

 Glenea multiguttata, Guer. 



REFERENCE. Guer. Voy. Deless. ii, 60 (1843). 



Habitat. Madura, Madras. 

 Tree Attacked. Odina wodier. Madura. 



Beetle. Head and prothorax pale or canary yellow, marked with black spots and lines ; 

 elytra orange brown, uifous brown, or greyish brown, the apical fourth pale or canary yellow, 



spotted with black; antennae shining rufous 



Description. brown, legs orange. Front of head with a 



black spade-shaped spot placed medianly 



and a median longitudinal stripe on vertex. Prothorax with four black 

 spots placed one above the other on either side of disk and four 

 others placed on either side laterally ; the yellow colour of head and 

 thorax is due to a fine dense pubescence. Elytra impressed at 

 shoulder, dull, striate- punctate, the diskal striae short and only 

 apparent in basal portion ; laterally, however, they extend to apex ; 

 punctures become less defined in apical portion; from a fourth to a p u;- 2 : 



fifth of apical portion covered with a dense yellow pubescence, with Gl e)U < a miiltiguttata 

 three spots of black pubescence, the largest towards base ; the outer Guer. Madras, 



edge of apex produced into a prominent spine. Under-surface 



clothed with a dense yellow pubescence spotted with black spots, forming a double row on 

 lateral part of abdomen. Length, lomm. to 21 mm. 



A specimen of this beetle was sent from Madura, Madras, with the 



information that it was taken from beneath the bark of 



Life History. an Odina wodier tree. I have no further information 



about its life history. The grubs probably feed in 



the bast layer of the tree.
