390 DR. G. A. K. MARSHALL ON THE SPECIES 



24. Balaninus commodus, sp. n. 



c? . Black, subnitid, thinly clothed above with recumbent 

 blackish scales or setae, and with markings formed of liroader 

 white scales; the prothorax with a subqnadrate basal wdiite patch 

 on each side opposite intervals 4-7 of the elytra ; the scutellum 

 with a few minute white scales ; the elytra with a few white 

 scales at the base of interval 2, behind the middle a macular 

 white patch on intervals 2 and 3, and another in line with it on 

 intervals 7 and 8 ; the lower surface fairly closely covered with 

 separated white scales and with the nsual denser lateral patches 

 of broader scales. 



The structural characters as in B. quincunic, sp. n., except the 

 following : — Head longitudinally convex, with the rostrum arising 

 about the middle of the eye. Bostrum a little longer than half 

 the body (5 : 9), the scrobe not exceeding the antenna. Pro- 

 thorax less abruptly constricted in front and with feeble post- 

 ocular lobes. Scutellum with a few white scales. Venter of J 

 with a shallow median impression on the anal segment, without 

 any tufts of hair or apical fringe; the pygidium with short 

 white set.ie. 



Length, 3*75 mm. ; breadth, 2 mm. 



Sarawak: 1 S , Quop, iv. 1914 {G. E. Bryant). 



25. Balaninus grypus, sp. n. (PI. II. fig. 12.) 



c5' . Just like a very small specimen of B. analis, sp. n,, but 

 the white markings differ as follows : there is no vertical apical 

 band on the prothorax and no apical lines on the elytra ; the 

 basal patches on the prothorax are broadly truncate internally 

 (instead of tapering to a point), and the postmedian band on the 

 elytra only reaches stria 8. 



The structural characters agree also, except in the following- 

 respects : the rostrum is longer in proportion to the body (5:7); 

 the f uniele has joint 1 equal to 2 ; the prothorax is more elongate 

 (9g-8), with the sides gently and more evenly rounded and 

 scarcely constricted at the apex, the sc\dpturing being propoi'- 

 tionately coarser ; the mid femora have no fringe of hairs 

 beneath ; the second ventral segment is not angulate externally, 

 and the fifth is quite simple and without any tufts of hairs ; the 

 pygidium is clothed with dense erect white sette (in B. analis and 

 imitator they are brown). 



Length. 2-75 mm.; breadth, 1"5 mm. 



Sarawak : 1 c?, Quop, 24. iii. 1914 {G. E. Bryant). 



26. Balaninus shelfordi, sp. n. (PI. II. fig. 15.) 



5 . Colour piceous brown, Avith dailv l)iown scaling and mark- 

 ings of fawn and white scales ; the prothorax with a nai-row 

 central stripe of transverse fawn scales, and on each side of the 

 base a quadrate patch (occupying one-fourth the width and extend- 

 ing longitudinally nearly to the middle) formed of fawn scales
