and strongly elevated above second : third and fourth each 

 with a single row of punctures across middle. Legs stout; 

 femora strongly dentate; all tibiae rather thin, lightly curved, 

 and somewhat narrowed to apex. Length, 5|-6^ mm. 



9 . Differs from the male in being somewhat stouter, 

 the rostrum somewhat thinner, longer, shining, and with 

 ;smaller and sparser punctures, especially towards the base; 

 antennas inserted not quite so close to apex of rostrum ; basal 

 segment of abdomen rather strongly convex, not polished, and 

 but feebly elevated above second.

In general appearance fairly close to several species of 

 the genus, but abdomen of the male highly distinctive. The 

 spots of pale scales on the elytra are not confined to the striae, 

 but are frequently continued across several interstices, giving 

 the surface a transversely fasciate appearance. The latero- 

 apical spots on the prothorax are rather feeble, and each is 

 composed of about six scales. The elytra appear to have four 

 dark spots, but these are due more to absence of pale scales 

 than to any other reason. There is a distinct depression 

 behind each eye, narrow and rather deep towards the sides, 

 and dilating towards the middle, so that the whole front of 

 the head is somewhat depressed ; this appearance, however, 

 is somewhat obscured by the clothing. Some of the large, 

 subbasal, elytral punctures are supplied with a small granule 

 at the middle of each side. 



Tyrt^osus alternatus, n. sp. 



Piceous-brown, in places obscurely diluted with red; 

 antennse reddish. Moderately densely clothed with 

 stramineous scales, on the prothorax each scale arising from 

 a puncture; on the elytra somewhat irregularly distributed, 

 and in parts mixed with sooty scales. 



Head with dense and coarse punctures ; a rather narrow 

 depression behind each eye. Rostrum moderatel}^ long, sides 

 regularly incurved to middle ; with dense and coarse 

 punctures, becoming crowded and irregular towards base, but 

 more or less linear in arrangement ; an impunctate median 

 line from near base to near apex. Prothorax with strongly 

 rounded sides; with dense, round, and rather large non- 

 -confluent punctures; with a distinct and narrow median 

 carina. Elytra subcordate, base distinctly wider than pro- 

 thorax, basal half almost parallel-sided; with rows of large 

 and somewhat angular punctures, becoming more rounded
