tral suture. There is a feeble incomplete pronotal carina. The beak 

 is finely densely punctate, striate laterally toward the base, though not 

 as conspicuously so as in elegans, median line cariniform basally ; 

 antennae inserted at middle. Ventral segments densely uniformly 

 punctate, the first with a median longitudinal impression, the fifth 

 rather broadly not deeply foveate at middle ; all else nearly as in ele- 

 gans. Length, 6.75 mm. ; width, 3.15 mm. 



Type. — From New Mexico. 



A single example of doubtful sex. Though obviously re- 

 lated to elegans it is quite different from anything else in our 

 fauna, and I have not been able to identify it with any Mexi- 

 can species.

 A. lysiiiiacliiae n. sp. — Closely allied to ventricosus and saltoides 

 and best described by comparison with these two species. In many 

 respects it occupies an intermediate position. The prothorax is more 

 nearly like ventricosus , but the sides are a little more oblique basally, 

 the elytra are shorter and more ventricose than in ventricosus, not per- 

 ceptibly longer than wide, humeri narrow and obtuse but distinct ; 

 elytral bands of narrow whitish scales, made up of elongate spots on 

 the intervals, the spots inclining to be better developed but not appre- 

 ciably more advanced on alternate intervals, as they are quite con- 

 spicuously in ventricosus. The space between the transverse bands is 

 a trifle darker owing to the presence of fine blackish feebly clavate in- 

 clined hairs which are also present elsewhere on the intervals and are 

 best observed in profile. The elytral striae are wider than in ventri- 

 cosus, but less so than in saltoides. Middle and hind tibiae strongly 

 unguiculate in the cf ; thighs scarcely toothed, In ventricosus the 

 elytra are quite distinctly longer then wide, in saltoides wider than long 

 according to Dietz, but in the single example before the length and 

 width are almost exactly equal. The humeri are a little better developed 

 in ventricosus, entirely wanting in saltoides, in which the thorax is 

 much shorter and more rapidly narrowed from the base, the elytral 

 striae deeper and wider, and the transverse bands ill-defined. The 

 sutural white spot at base of elytra is present in all, but most distinct 

 in ventricosus. In many specimens of lysimachiae the elytra are red- 

 dish-brown, in others dark brown, perhaps indicating different stages 

 of maturity. Length, 2.5-3 mm. ; width, 1.7-2 mm. 



Type. — c5^; from Tyngsboro, Massachusetts. 



Taken abundantly in September on Lysimachia stricta by 

 Mr. Frederick Blanchard, to whom I am indebted for a good 

 series of specimens.
