timate, lightly incrassate. Maxillary palpi long ; apical joint 

 a little longer than penultimate ; in form like a narrow com- 

 pressed club. Maxillae with external angle of cardo forming a 

 short triangular process ; inner lobe wide, apex wide, rounded, 

 plurisetose, projecting beyond the spiniform hook. Prothorax 

 hexagonal, widest and obtusely angulate at middle, strongly 

 obliquely angustate to base ; apex truncate ; anterior angles 

 marked and raised in cT , rounded in 9 • Elytra striate ; striae 

 minutely punctate ; interstices depressed, 2-7 with three rows, 

 eighth with four rows of punctures, third with four widely 

 placed dorsal punctures ; humeral angles rounded in cf • Pro- 

 sternum strongly declivous to apex ; a strong transverse sulcus 

 near anterior margin. Tarsi setose; fourth joint narrow, entire; 

 anterior in ^ with second and third joints dilatate and biseri- 

 ately squamose beneath. 



Neohelluo is nearer to ^J^nigma than to any other genus ; it 

 also shows some affinity, though remote, to Gigadema maxil- 

 lare SI. It differs from J^ nig ma by lab rum shorter; mentum 

 triangularly pointed, not with epilobes developed into strong 

 curved mucrones ; ligula with apex more prominent in middle ; 

 fringe of setae longer ; inner surface plurisetose towards base ; 

 maxillae with inner lobe more setose, especially at tip, apex 

 projecting far more beyond hook ; prothorax differently 

 shaped, basal angle near peduncle, elytra in $ without humeral 

 tooth, etc. 



Neohelluo angulicollis, n.sp. 



cf. Black. Head large (3-9 mm. across eyes); mandibles 

 very long, curved, bent downward to apex from middle. Pro- 

 thorax broader than long (4 x 4-6 mm.), wider across apex (2-7 

 mm.) than base (2-3 mm.), ampliate and roundly subangulate 

 at middle of sides ; disc convex ; sides obliquely narrowed to 

 apex and base ; anterior margin truncate ; angles prominent, 

 obtuse, reflexed ; lateral margins punctate, wide, strongly re- 

 flexed ; basal angles near peduncle. Elytra much wider than 

 prothorax (11 x 6-7 mm), striate; striae minutely punctate;
