appearing at basal third or fourth ; disk without impressed lines, the punc- 

 tures of the distant series obsolete throughout the width, and only indicated 

 by the extremely minute recumbent hairs growing from slightly more marked 

 retal lines at their points of origin. Under surface and legs normal, the 

 second joint of the posterior tarsi short, about one-half longer than the first ; 

 tibial spurs very small and slender. Length 1.5 mm. 



Flovida (Lake Poinsett). Mr. Schwarz. 



A small species allied to apicalis and consimilis, but distinguished 

 from the former by its smaller size, more broadly oval, less convex 

 and more posteriorly attenuate form, and elytral reticulation, and 

 from the latter by its shorter prothorax, more abruptly marked 

 apical pale area, less convex form and other characters. 



S. OlJSCUrilS n. sp. — Rather broadly oval, piceous above ; antennse, legs 

 and under surface pale testaceous ; upper surface polished. Head extremely 

 feebly and sparsely punctate ; antennae rather slender, third joint shorter than 

 the next two together, fourth much shorter than the fifth, club rather slender, 

 sides nearly parallel, ninth joint much longer than the tenth and slightly 

 shorter than the eleventh. Prothorax scarcely visibly and very sparsely 

 punctate, not reticulate ; basal lobe very broad and feeble, the marginal bead 

 almost obsolete. Scutellum one-half wider than long. Elytra more strongly 

 narrowed behind in apical half, rather strongly rounded at apex, unicolorous 

 or sometimes very feebly paler toward apex ; discal stria strong, obsolete at 

 basal third or fourth, punctured as in apicalis; surface finely, feebly but dis. 

 tinctly reticulate, the reticulations visible over the entire surface except in the 

 vicinity of the base, where they become obsolete, generally in very broken wavy 

 lines on the upper portions of the disk. Abdomen very strongly reticulate, the 

 portions very near the base, and also the metasternum toward the sides, almost 

 granulose. Legs moderate ; posterior tarsi rather short and robust, scarcely 

 two-thirds as long as the tibise, setose beneath, the first joint two-thirds as long 

 as the second ; tibial spurs small. Length 1.8-2.0 mm. 



Iowa. Mr. Wickham. 



The metasternal process is rather wider than in apicalis, and the 

 mesosternum in front of it is very strongly tumid and prominent. 

 The sexual characters are nearly as in viduus, except that the tooth 

 of the third segment is more deflexed, with the spinules excessively 

 short. This species is very easily distinguishable from apicalis and 

 viduus by its small size, more rounded form, dark piceous color, 

 which does not become noticeably paler at apex except from the 

 transparency of the elytra, and by the reticulation of the upper 

 surface ; it is represented by a good series of specimens, and does 

 not vary appreciably.
