3797. Diglymma thoracicum sp. nov. 
Hlongate, moderately convex and nitid ; piceo-niger, legs and antennae 
piceo-rufus ; palpi castaneous, all the joints testaceous at the extremity. 
Head, eyes included, only a fifth narrower than the middle of thorax, 
depressed and with a series of moderate punctures behind the eyes, the 
vertex minutely, indistinctly, and distantly punctate; labrum deeply 
medially emarginate. Thorax elongate, just an eighth broader than long, 
base and apex truncate, its sides distinctly and evenly marginate, very 
slightly rounded, more evidently, but not at all abruptly, near the base so 
that its angles are obsolete; discal channel apparently entire when ex- 
amined from above, a little shallower near the base and apex, with some 
scattered but not coarse punctures across the base and front, basal fossae 
deep and elongate. lytra nearly thrice the length of thorax, a third 
broader before the middle than it is, gradually but obviously narrowed 
behind that point, apices not at all broad} lateral margins distinct, rather 
more so near the curvedly narrowed shoulders ; their striae rather fine 
yet quite definite nearly to the extremity, they are finely but not closely 
punctured ; interstices simple, the sides with about 5 coarse setigerous 
punctures. 
Terminal articulations of maxillary palpi quite elongate-oval, obtuse at 
the extremity, less slender than those of Sharp’s D. ovipenne or D. dubiwm. 
Antennae pubescent from the 4th joimt onwards, extending to the 
middle of the thorax, joints 5-10 submoniliform. 
After carefully comparing the only available specimen, a female satu- 
rated with alcohol, with all the types in my collection I failed to find any 
exactly like it. D. obtusum (1454), D. punctipenne (1768), and others with 
obtuse or obsolete posterior thoracic angles present more or less distinct 
disparities. D. basale, and others belonging to the same section, can be 
readily separated by looking at the hind angles of the thorax. 
Length, 10mm.; breadth, 34mm.

summer of 1915 by Mr. W. Trail.

p. 16. 
Suboblong, moderately convex, nitid; black, femora piceous; tibiae, 
tarsi, antennae, epistome, and labrum more or less piceo-rufous; palpi 
fusco-fulvous. 
Head and eyes as broad as front of thorax, oviform, somewhat uneven, 
finely obliquely wrinkled and opaque between the eyes. Thorax quite 
cordate, a third broader than long, its apex widely emarginate, so that 
the obtuse angles extend forwards beyond it; the sides with reflexed 
well-developed “margins, evidently rounded as far as the middle, rather 
deeply smuate towards the subrectangular and slightly prominent angles, 
base medially incurved ; its surface somewhat uneven, basal fossae large, 
situated between the middle and sides, sometimes interruptedly prolonged 
nearly to the apex, mesial furrow deep, abbreviated in front. Elytra 
oblong-oval, thrice the length and nearly double the width of thorax, 
broader than it is at the base, curvedly narrowed but not sinuate pos- 
teriorly, with broadly rounded apices; their impunctate striae deep near
