On Species of hain^ from the Mahnjan Ryion. 103 



XVII, — On some Additional Species of Laius, Guerin, from 

 the Malayan Region [Coleoptera]. By G. C. Champion, 

 F.Z.S. 



About a fortniglit after my paper on tlie geuus Laius 

 appeared in tliis Magazine, (9) vii. pp. 322-343, April 1921, 

 a very interesting series of Malayan forms was received at 

 the British Museum from Mr. C. F. Baker, of Los Bafios, 

 Luzon, Philippines. This set includes 14 species, 12 of 

 which were new to the collection and 9 of them undescribed. 

 It is advisable to name these insects at once and to incor- 

 porate them with the rest in the Museum. Seven belong 

 to the Intybia-group, placed by me near the end of the 

 genus ; and one has the second tarsal joint of the (^ produced 

 into a long claw above, as in the same sex of Attains, this 

 being the first species of Laius seen by me witli the tarsi 

 thus formed. The Philippine L. baeri, Fairm. (1898), 

 and L. semidepressus, Pic * (1917), and various forms 

 from Java, Celebes, Perak, &c., named by Pic, have 7iot yet 

 been found in the collections examined. For facility of 

 reference Mr. Baker's numbers are quoted in the present 

 })aper. In addition to the species of Laius he has also sent 

 a new Hapalochrus closely related to H. orientalis, descri!)ed 

 in the same number of the ' Annals/ p. 346 *. The Ma- 



* Hapalochrus ineffahps, sp. n. — cJ . Elongate, narrow, CDnvex, shining, 

 ciuereo-pubescent, with scattered, longer, semierect hairs intermixed ; 

 bluish-green, the autennfe (the testaceous basal joints excepted), eves, 

 and legs black or piceous ; the head and prothorax sparsely, the el\-tra 

 densely, verv tiuely punctured. Head a little broader than the pro- 

 thorax, the eyes extremely large, sepai-ated by less than theh- own width 

 as seen from above ; auteunse long, tlabellate. Prothorax transverse, 

 rounded at the sides. Elytra long, slightly widening posteriorly. 

 Anterior tibi<e hollowed near the apex within ; anterior tarsal joint 2 

 extending over the base of 3 above ; intermediate tibife widened, rounded 

 externally, not sinuate within. 



Length 3^ mm. 



Hab. Singapore (BaA-er: Xo. 16161). 



One male. Very like the S. Indian H. orientalis, Cliamp. [/. c. 

 p. 346, no. 69 (c)], differing from it, in the J -sex, by the very much 

 larger and more contiguous eyes, the pale basal joints of the antennie, 

 the widened, subarcuate intermediate tibiae, and the finer puncturing of 

 t'le elytra. The 5 only 6i H. orientalis was described: the J, a s])eci- 

 men of wliich taken by Dr. Campbell at Yen-aud, S. India, has just been 

 presented to the British Museum by Mr. E. A. Butler, has, as antii-i- 

 pated, strongly tlabellate anteinue; "the anterior and intermediate tibiie 

 slender, and both hollowed near the apex within; the eyes moderately 

 large and widely separated ; and the body brilliant cyaneoiis above.
