214. Tyrtaeosus interstitialis, n. sp. 
Black, rostrum somewhat paler: antennae and claw joints of a dull red. Mo- 
derately densely clothed with stout, subsetose scales. 
Head with dense partially concealed punetures. Rostrum stout, about two- 
thirds the length of prothorax; with dense punctures, partially concealed at basal 
third. Antennae rather stout, first joint of funicle distinetly longer than second. 
Prothorax moderately convex and transverse, sides strongly rounded, base bisinuate 
and twice the width of apex, with a continuous but not acute median carina; with 
dense, round and clearly defined but rather shallow punetures.. Scutellum round 
but with a short basal, projection. Elytra not much wider than prothorax, sides 
feebly rounded to beyond the middle; with regular rows of rather large, elongate, 
suboblong punctures; interstices flat, not alternately raised, considerably wider than 
punetures, themselves with dense and rather eoarse punetures. Mesosternal recep- 
tacle strongly raised in front, widely U-shaped. Side pieces of metasternum with 
dense punctures in two irregular rows. Abdomen somewhat flattened; with fairly 
dense punctures; second segment about two thirds the length of first, and once and 
one fourth the length of third; third and fourth with punctures as on the other 
segments. Liegs rather short, femora moderately dentate. Length S—10 mm.

Most of the scales are of a dull stramineous colour and rather elosely applied 
to the derm, but on the elytra many of them are of a dingy brown, and so placed 
as to cause a feeble mottled appearance. The scutellum is of unusual shape. 
Regarding the prothorax as rather feebly carinated then in the table previously 
given by me, it should be placed with sekthyosomus, from which it may be distinguished 
by its larger size, by the carina extending to both base and apex, and by the third 
and fourth abdominal segments and the side pieces of the metasternum with dense 
punetures. It is rather more elliptie in outline than the majority of species of the 
genus, and in general appearance is somewhat suggestive of Therebiosoma and Pseudo- 
therebus, but the cavernous mesosternal receptacle readily distinguishes it from 
those genera.
