23,8 Heller: Some new Malayan Carabidx 297 



solum ad basin observances ac in parte apicali manifestos, hie 

 spatiis costatis ; metasterno lateribus episternisque haud puncta- 

 tis; sternito abdominali tertio quartoque secundum marginem 

 basalem sat late, primo secundoque lateribus vix punctulatis. 

 Long. 17.5 ad 20.5, lat. 4.5 ad 5 mm. 



Luzon, Benguet Province, Baguio: Zambales Province, Iba 

 (W. Schultze). 



This species can be readily recognized by the rugulose front 

 which bears a conical tubercle in the middle, by the lack of a 

 basal impression on each side of prothorax, and by the obsolete 

 three interior elytral striae which are distinct only at the base 

 and toward the apex. The specimen from Zambales Province is 

 smaller and shows an obsolete frontal tubercle but agrees in 

 other respects with a smaller specimen of T. integricollis. 

 Thlibops abbreviatus sp. nov. 



Thlibops intermedio m. similis, sed fronte tuberculo conico 

 armata; prothorace linea mediana distinctius remote seriato- 

 punctata; elytris spatiis alternatis latioribus ac convexioribus 

 apice abbreviatis et hie haud confluentibus, spatio septimo parte 

 apicali inflato ac ordine suturam attingente ; metasterno lateribus 

 episternisque perparce, abdomen fere toto punctato, sternito ab- 

 dominali praeterea transverse rugoso. Long. 18.5, lat. 3.3 mm. 



Luzon, Rizal Province, Montalban (W. Schultze). 



Differs from all the other Philippine species by the shorter 

 intervals of elytra, which are alternately much broader and 

 more convex and not confluent at the apex. The metasternum 

 and metaepisterna are sparsely rugose, the last three ventral 

 abdominal segments throughout distinctly punctate, and the 

 anal segment is transversely rugose. 



The known species of the genus Thlibops Putz. (T. longicol- 

 lis Putz., T. puncticollis Gestro, and T. paviei Lesne I know 

 only from the descriptions) can be distinguished by the follow- 

 ing characters: 



1 (17). Prothorax with a distinct sulciform basal impression on each side. 



2 (7). All striae of elytra entirely punctate-striate. 



3 (4). Sides of prothorax with sparse unequal punctures; length, 11 



millimeters. Burma - T. puncticolUs Gestro. 1 



4 (3). Sides of prothorax without punctures. 



5 (6). Second and fourth intervals of elytra without punctures; length, 



15 millimeters. Cochin-China T. crenata Chaudoir. 



6 (5). Second and fourth intervals of elytra with four or five remote 



punctures; length, 9 millimeters. Gabun... T. longicollis Putz.
