420 Mr. G. Lewis on 
Teretriosoma peruanum. 
Teretrius peruanus, Ey. Wiegm. Arch. i. p. 91 (1847). 
The type of this species in the Berlin Museum has been 
examined at my request by Herr H. Kolbe, and I am able to 
state that it has no prosternal striae and it therefore belongs 
to the genus Teretriosoma. It is a species which requires 
redescription. 
Note.—In ‘Departmental Notes on Insects that affect 
Forestry,’ no. 1, p. 20 (1902), published in India, Mr. E. P. 
Stebbing states that Teretriosoma cristatum, Lew., intrusum, 
Mars., and Stebbingi?, Lew., have been found by him in the 
galleries in trees made by a species of Stnoxylon in the 
Shahdera and Changa Manga plantations of the Lahore divi- 
_ sion of the Punjab; and also that Nipontus Andrewest, Lew., 
has been found in the galleries made by a Scolytus. 
Apobletes tristriatus. 
- Apobletes foliaceus, Mars. Mon. p. 245, t. 6. f. 3 (1853); Sch. Ann. 
Soc. Ent. Fr. 1xi. p. 290 (1892). 
This is a new name for a species with three dorsal striz, 
described erroneously by Marseul as A. folvaceus, Paykull. 
ALTHANUS, gen. nov. 
Body cylindrical, somewhat elongate, and truncate; head 
retractile, forehead concave, mandibles robust and coequal ; 
antenne, scape as long as the funicle and club together, 
funicle with 7 short joints, club rather large and 4-jointed ; 
thorax, marginal stria very fine, antennal fossettes in the 
angle and wholly open below; elytra, striee chiefly obliterated ; 
prosternum keel narrow; mesosternum rather wider than 
long and markedly marginate and sinuous anteriorly ; anterior 
tibia 4-dentate, apical tooth very robust, posterior tibize not 
spinose except at their apices. 
The sterna in this genus resemble those of Cylisti# and the 
antennal fossettes are similar to these of Platysoma. 
Althanus teretrioides, sp. n. 
Cylindricus, brunneus, nitidus ; fronte stria laterali valida in medio 
angulata; pronoto stria marginali tenuissima necnon basi con- 
tinuata, stria laterali pone oculos interrupta; elytris striis dor- 
salibus inconspicuis ; prosterno inter coxas bistriato; mesosterno 
valide marginato ; tibiis posticis extus haud denticulatis.
