150. COENONICA FORMOSAE, new species 



Foreparts moderately shining: head black, thorax dark brown; 

 elytra brownish yellow scarcel}^ infuscate postero-externally ; ab- 

 domen much more shining, black, the raised side and posterior mar- 

 gins of the tergites broadly yellowish red. Antennae black, the first 

 three segments and legs reddish yellow. Near philippina Bernhauer 

 but larger, the punctures of head larger and not so close, the thoracic 

 impressions weaker, the elytra much more finely, not asperately punc- 

 tured, the antennae longer and stouter. Head narrower than the 

 thorax (1.75 : 2.5), the eye a little shorter than the postocular region, 

 impunctate in front and on vertex, elsewhere with small, rather close 

 umbilicate punctures. Antennae moderately long, rather stout, the 

 second and third segments of equal length, fourth a little longer than 

 broad, fifth to tenth transverse, the penultimate about twice as broad 

 as long. Thorax transverse (2.5:2), the sides rounded in front, re- 

 tracted and slightly sinuate before the obtuse and somewhat prom- 

 inent posterior angles, in the posterior half before the middle of the 

 base with a pair of parallel longitudinal sulci, the puncturation rather 

 close and like the head. Elytra longer (2.2: 2) and broader than the 

 thorax, broader than long (3:2.2), the punctures simple, much finer 

 and much less close. Abdomen a little narrowed before the apex, 

 very finely and very sparingly punctured. Except for a fine coriaceous 

 ground sculpture at the base of the head, the whole insect without 

 ground sculpture. In the two examples no secondary sexual char- 

 acters are present. Length, 3-3.2 mm.
