Tlioracocliirus timhilicatuSy n. sp. 



IJl.ack, shining- ; thorax strongly transverse, uneven ; sculpture coarse and 

 iin)bilicate; elytra square, puncturation crateriform ; antennae, legs, and last 

 abdominal segment pitcLy-red. Length 6'5 mm. Very near T. variolosus 

 F«uv., from Burma, from which it differs in the following respects : it is 

 rather larger and more robust, the front of tiie head is less wrinkled, the 

 thornx has on either side of the middle line a rather large impression and 

 parallel with the side-margin is another impression, the surface thus appears 

 uneven, and this is fur her accentuated by the presence of irregular, more or 

 less indeterminate and fine plications towards the sides. Head subtviangular, 

 transverse, eyes very prominent ; front sparingly wrinkled, the sides and front 

 broadly rounded ; v^^rtex with a rather broad and deep furrow, the sides of the 

 disc with a few fine umbilicate punctures ; antennal tuberosities rounded, 

 elevated, reddish ; mouth-parts reddish-testaceous. Antennae rather long, 

 reddish, the 2nd joint considerably shorter than the 3rd, the 4th to the 8th 

 joints longer than broad, gradually decreasing in length, the 9th and 10th as 

 long as broad, tlio 11th oval. Thorax strongly transverse, the middle of the 

 disc with a deep longitudinal groove extending from the anterior margin to a 

 deep transverse groove in front of the posterior margin in which it ends ; ou 

 either side of the middle is a rounded impression, and parallel to the lateral 

 margin a longitudinal, somewhat obsolete, groove; the surface covered, except 

 in the impressions and grooves, with large umbilicate punctures, the sides 

 crenulate and setiferous. Scutellum sparingly and tinely punctured centrallv. 

 Elytra square ; sculpture crateriform, giving a very rough surface and causing 

 the sides when seen from above to appear crenulate : there is no appreciable 

 difference to be detected between it and that of 2\ variolosus. Abdomen, 

 except for a more or less obsolete row of punctures in front of the posterior 

 margin of each segment, almost impunctate ; pubescence scanty, long, and still".

Thoracochirus exasperatus. ii. sp. 



Black or pitchy-black, moderately shining; antennal tubercles, antennae, 

 mouth-parts, legs, and anus reddish-testaceous; head (except the front), thorax, 

 and elytra ui/iforndy sculptured with crateriform puncturation ; abdomen tinelv, 

 uniformly, but not closely, punctured. Length 4 mm. From the de.^cription 

 this species would appear to be closely related to T. aspericollis Fauv., but to 

 differ from it in the following points : the smaller size, the uniform close punc- 

 turation of the vertex of the head and the tliorax, and the much less sparing 

 abdominal puncturation, which is well marked in this species. Head sub- 

 tnangular, transverse; eyes very prominent; the front depressed declivous, 

 without visible sculpture ; the clypeus truncate in fiont, with a short elevated 

 ridge on either side ; the vertex witliout groove or impression, closely aiid 

 uniformly covered with crateriform puncturation ; pubescence r ther long, 

 yellowish. Antennae moderatelv lonL^ the 1st joint elonuat* f^raduallv
