these usually being traceable only by their contained scales, 

 but on abrasion they are seen (except on the posterior 

 declivity) to be large, and almost, in places quite, as wide as 

 the interstices ; these also are seen to have feeble granules 

 that are normally quite concealed. 



Tyrt^osus bifasciatus, n. sp. 



d . Black, in places sometimes obscurely diluted with 

 red; antennas and tarsi reddish. Upper-surface with dingy- 

 Thrown or sooty scales, seldom rising to general level. Elytra 

 with a distinct but irregular fascia of soft white scales at 

 iDasal third, remnants of another at summit of posterior 

 declivity, and with two apical spots. Under-surface and legs 

 with more or less whitish scales and setae. 



Head with coarse crowded punctures in front, becoming 

 smaller posteriorly. Eyes separated the width of base of 

 rostrum, a partially-concealed depression behind each. 

 Rostrum rather short and stout, feebly dilated to apex ; with 

 coarse crowded punctures quite as large at apex as at base. 

 Club rather larger than usual. Prothorax strongly trans- 

 verse; sides of basal three-fourths rather lightly rounded, 

 then suddenly narrowed, apex less than half the width of 

 base ; with dense, and rather large, round, deep, non- 

 confluent punctures; median carina rather feeble and 

 irregular but traceable throughout. Elytra elongate-cordate, 

 not much wider than prothorax, basal half parallel-sided, 

 subhumeral incurvature very feeble ; with rows of large punc- 

 tures, each of which is separated by a depressed transverse 

 ridge on basal two-thirds, posteriorly with smaller punctures 

 and deeper striae; interstices about the width of punctures, 

 each with a more or less irregular row of distinct punctures, 

 and with many feeble transverse impressions. M etasternum 

 with a strong ridge on each side between coxae; punctures 

 of episterna interrupted. Abdomen with first segment feebly 

 depressed in middle, apex widely and feebly produced in 

 middle, where the length is slightly more than that of third 

 and fourth combined, second along middle very little longer 

 than third or fourth, each of these with an irregular double 

 row of punctures across middle. Legs stout; femora rather 

 strongly dentate ; hind tibiae moderately dilated at apex. 

 Xiength, 5J-6 mm. 



9 . Differs in having the abdomen with basal segment 

 uniformly convex, its apex not produced, and second segment 

 distinctly longer than third or fourth.

The head and rostrum is much as in crassirostris, but that 

 species has edentate femora. One specimen has a vague white
