On Species of l^'Axn^ from the Malayan Rgion. 193 



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

 the Malayan Region [Coleoplei'a]. By G. C. Champion, 

 F.Z.S. 



About a fortnight after my paper on the genus Laius 

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

 a very interesting series of Malayan forms was received at 

 the Britisli Museum from Mr. C. F. Baker, of Los Bancs, 

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

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

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

 porate them with the rest in the Museum. Seven belong 

 to the Inti/bia-^voii\:i, 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 witii the tarsi 

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

 and L. seinidepressus, Pic (1917), and various forms 

 from Java, Celebes, Perak, &c., named by Pic, have not yet 

 been found in the collections examined. For facility of 

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

 paper. In addition to the species of Laius he has also sent 

 a new Hapalochrus closely related to H. orientalis, described 

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



* Hapalochrus megalops, sp. n. — (^ . Elongate, narrow, convex, shining, 

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

 blnish-green, the antennae (the testaceous basal joints excepted), eyes, 

 and legs black or piceous ; the liead and prothorax sparsely, the elytra 

 densely, very finely punctured. Head a little broader than the pro- 

 thorax, the eyes extremely large, separated by less than their own width 

 as seen trom above ; antennaj long, tlabellate. Prothorax transverse, 

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

 Anterior tibife hollowed near the apex within ; anterior tarsal joint 2 

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

 externally, not sinuate within. 



Length 3^ mm. 



Hub. Singapore (Baker: No. 16161). 



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

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

 larger and more contiguous eyes, the pale basal joints of the anteniia3, 

 the widened, subarcuate intermediate tibijc, and the finer puncturi<ig of 

 the elytra. The 2 only of if . orientalis was described: the cJ, a speci- 

 men of which taken by Dr. Campbell at Yercaud, S. India, has juf^t been 

 presented to the British Museum by Mr. E. \. Butler, has, as antici- 

 pated, strongly fiabellate antennae; the anterior and intermediate tibi;e 

 s'.ender, and both hollowed near the apex witliin ; the eyes moderately 

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