enlarged to the apex, broader than the preceding joint at the 
extremity, the fourth very small, subulate. Inner lobe of 
maxilla narrow and pointed, furnished with four or five 
moderately long, but slender pectinatious ; outer lobe very 
similar in size and shape to the inner one, the apex ciliate. 
Tongue rather short, but longer than broad, split nearly to 
the base into two narrow lobes, reaching the level of the 
apex of the first jomt of the labial palpi. Labial. palpi 
3-jointed, the first joint rather short and stout (about twice 
as long as broad), the second much narrower and shorter 
than the first, the third cylindrical, about three times longer 
than the preceding. Gular sutures long and_ parallel. 
‘Temples not bordered below. Prosternum broadly rounded 
behind. Mesosternal process narrow and pointed, extending 
about half the length of the intermediate coxze, which are 
very narrowly separated. 'Tarsi4, 4, 5, the anterior pair with 
the first three joints short and subequal ; the intermediate 
with the first three joints rather short and subequal, the 
fourth as long as the three preceding together ; posterior 
pair with the first three joints rather short and subequal, 
the fourth yet shorter, the fifth as long as the two preceding 
together. Elytra not sinuate. 
This genus is evidently closely allied to Thecturita, Casey, 
which it resembles in the parallel, rather depressed build, 
large head, unbordered temples, etc. ; but differs in the bifid 
tongue and the different proportions of the joints of the 
labial palpi. Appears to differ from Oligurota, Cas., by the 
bifid tongue, shorter head, small eyes, etc. 
98. Thecturella insidiosa, sp. n. 
(Homalota insidiosa, Fauvel, in litt.) 
Minute, parallel, subdepressed, rather shining, dark chest- 
nut-brown ; the elytra testaceous; the abdomen black, 
shining, the apex testaceous. Antenne and legs testaceous. 
Length 1:1 mm. 
Head large, quadrate, nearly as wide as the thorax, deeply 
sulcate longitudinally in the middle, very finely and mode- 
rately closely punctured at the sides, the sulcus impunctate ; 
eyes small, their diameter much less than the length of the 
temples. Antenne rather short, the third joint much 
shorter than the second, the fourth to the tenth transverse, 
gradually increasing in breadth, the penultimate two and a 
half times broader than long. Thorax slightly transverse, 
widest a little before the middle, the sides scarcely rounded 
in front, quite straight, and but feebly narrowed behind to
