even with the head retracted some of the bald portion is 

 visible. Each of the metasternal episterna appears to be 

 thickened at its suture with the metasternum, so that a fairly- 

 conspicuous impunctate ridge appears, between which and the 

 elytron is a fairly distinct row of punctures; as the ridge is 

 without a triangular frontal projection it probably belongs 

 to the metasternum itself. The tips of the prothorax and 

 of the elytra are sometimes diluted with red. On the pro- 

 thorax there are usually three feeble lines of setae; on the 

 elytra the clothing is mostly compacted into fairly numerous 

 but feeble fascicles. 



Decilaus suturalis, n. sp. 



Black; antennae and tarsi reddish. Prothorax with sooty 

 varied with greyish and stramineous scales, nearly all elevated 

 above the derm ; elytra with dense sooty scales, closely applied 

 to derm, but feebly variegated with pale ones, and with some 

 stiff suberect white and sooty scales scattered about. Under- 

 surface with stiff white or whitish scales; legs with clothing 

 mostly sooty, head in front and basal half of rostrum with 

 stout pale scales. 



Head with coarse partially-concealed punctures; basal 

 part bald. Eyes separated the width of rostrum at base. 

 Rostrum stout, rather short, with dense and coarse punctures, 

 partially concealed but seriate in arrangement behind 

 antennae, and with a narrow median carina. Scape inserted 

 one-third from apex of rostrum, almost the length of funicle; 

 club large. Prothorax moderately transverse, sides strongly 

 rounded, apex about two-thirds the width of base ; with dense, 

 deep, and fairly large punctures. Elytra rather long, sub- 

 cordate, sides strongly rounded and widest at basal fourth: 

 with rows of large partially-concealed punctures, in distinct 

 striae. Mesosternal receptacle strongly elevated and rather 

 lightly curved. Abdomen with dense partially-concealed 

 punctures, third and fourth segments somewhat depressed. 

 Femora stout, strongly grooved, edentate. Length, 2 mm.

The size and colour similar to the preceding species, but 

 clothing very different. The ridge at the side of the meta- 

 sternum is thinner, but being clothed with pale scales is rather 

 more conspicuous. The elytral margins, except in middle, are 

 somewhat thickened and feebly shining. The type appears 

 to have a vague remnant of a median prothoracic carina. As 

 the basal segment of its abdomen is flattened in the middle 

 it is probably a male. The seriate punctures are very distinct
