StilipJiacis exigua (Erichson) Bierig, 1938a, p. 142. 



Def^crnption. — Rufopiceous, elytra and abdomen testaceous, elytra 

 usually with a black lateral spot. Head large, subquadrate, as wide 

 as elytra; eyes large, prominerit; sides behind eyes straight for less 

 ihan length of eyes, then abruptly constricted; closely but coarsely 

 umbilicately punctured; antennal segments transverse from the third; 

 labrum feebly broadly lobed at center, on each side of lobe with a 

 minute tooth. Pronotum scarcely wider than long, seven-eighths as 

 wide as head and elytra, widest at anterior fourth, strongly narrowed 

 and rounded in front, feebly narrowed posteriorly ; sides finely tuber- 

 culate; punctation similar to that of head. Prosteriiwn rather indis- 

 tinctly longitudinally carinate on the disk. Elytra nearly as long as 

 broad, a little longer than pronotum ; moderately but densely punctate. 

 Abdomen shining, indistinctly punctate, pubescent. Male^ seventh 

 sternite with a broad shallow emargination ; eighth broadly and deeply 

 emarginate. Length, 2^-^ to 3 mm. 



Type locality. — Puerto Kico. Of circumflexus^ "Mustique I., Grena- 

 dines, W. I."; of auripills, Mount Gay Estate, Grenada. 



Types. — In either the Hope Museum, Oxford, or the Zoologische 

 Museum, Berlin. Tlie types of cireumf exits and aurlpilis are in the 

 Briti.sh Museum. 



Records. — The following are the records known to me : 



Puerto Rico: (Erichson, 1840; Leng and Mutchler, 1914; Wolcott, 1924), Jayuya 



(Wolcott, 1936). 

 Grenadines: Mustique (Cameron, 1913, as circumfiexus; Leng and Mutchler, 



1917, as circumfiexus). 

 Grenada: (Cameron, 1913, as auripiUs; Leng and Mutchler, 1917, as auripilis). 

 Trinidad: St. Augustine (Weber, in M.C.Z.). 



Specimens examined. — I have examined 43 specimens in the British 

 Museum, 5 in the collection of Dr. Cameron, and 1 from the Museum 

 of Comparative Zoology. 



Remarks. — I am unable to accept as of specific importance the char- 

 acters mentioned by Dr. Cameron to separate his specimens from 

 Grenada and Mustique. A specimen of each series that I borrowed 

 from the British Museum for further study differ in degree from the 

 descriptions in various points and seem to be inseparable by any char- 

 acter other than depth of color and extent of infuscation of the elytra. 



Ti)ese differ in no way from the description of S. exigiiu (Erichson) 

 except those with the elytra infuscate laterally. I found no specimens 

 labelled exigua in either the British Museum or Dr. Cameron's collec- 

 tion and therefore conclude that he overlooked this name. 



T find no record of the habits of this species.
