278 GUY A. K. MARSHALL. 



the scape short, just reaching the eye. Prothorax a little longer than broad, the 

 sides subparallel from the base to beyond the middle, then roundly narrowed and 

 very deeply constricted near the apex, the constriction continued across the dorsum 

 as a deep curved furrow ; the apical margin truncate or very slightly sinuate, the 

 base truncate ; the dorsum gently convex transversely and evenly set throughout 

 with small separated punctures, the interspaces being as broad as the punctures 

 themselves ; on the sides the punctures are rather larger and much closer together. 

 Elytra elongate- ovate, slightly sinuate jointly at the base, and without any hu- 

 meral prominence ; the sides gently curved, broadest at a short distance from 

 the base, then rather rapidly narrowing to the apex, which is broadly rounded ;. 

 the striae containing rows of shallow distant punctures, which encroach slightly 

 on the sides of the convex impunctate intervals. 



Length, 1"6-1"8 mm.; breadth, 0"6-0'7 mm. 



Haw^aian Is. : 2 cJ c?, 8 ? ?, Kaimuki, Oahu, 19.ii.l920 (0. H. Swezey). 



The genotype, S. fryi, WoU., from Mexico, differs in its slightly larger size ; the 

 scape extends behind the eye ; the eyes are not quite confluent beneath ; the head 

 is opaque and coarsely punctate ; the rostrum is markedly shorter ; the prothorax 

 is broader and much more coarsely punctate, the interspaces being much narrower 

 than the punctures, etc. 



This species was found by Mr. Swezey breeding in numbers in the root (corm)- 

 of a banana plant.
