Pine. Lake Co., Ind., May 15-20: Alineral Springs. Porter Co., 

 Sept. 10. Taken by A. B. Wolcott in the sand covered district along 

 Lake Michigan where it occurs mainly beneath the prickly pear 

 cactus Opuntia humifusa Raf. This species was erroneously included 

 in the Coleoptera of Indiana, p. 1192, as L. aliernatus Ziegl., but that 

 species is non-alutaceous and has the antennal joints, 2, 3 and 4 

 subequal. Mr. Fall has compared for me the type of arenaccns with 

 that of Ziegler's species and pronounces the two very distinct. 



Longitarsus suspectus new species. 



Rather broadly oval, convex ; winged. Pale reddish-yellow throughout, 

 strongly shining; apical third of antennae often dusky. Head alutaceous, im- 

 punctate, the frontal carina prominent. Antennal joints 2, 3, 4 gradually 

 slightly longer, the fourth one-half longer than second, but slightly if any 

 shorter than those which follow, which are subequal. Thorax sub-elliptical, 

 one-third wider than long, sides strongly declivent ; front angles with a small 

 obliquely truncated nodule, hind ones rounded into base : disk minutely aluta- 

 ceous, very finely and remotely punctate. Elytra wholly covering the pygidium, 

 one-third wider at base than thorax, humeri rounded, umbone evident but 

 feeble ; sides very broadly curved, sutural angle obtuse ; disk finely but dis- 

 tinctly alutaceous, finely, evenly and very shallowly punctate, the punctures 

 separated by nearly twice their own diameters and subseriate in arrangement. 

 Abdomen finely and sparsely punctate, each puncture bearing a minute inclined 

 yellowish hair. Length, 1.8-2 mm. 



Pulaski, Putnam, Marion. Knox and Dubois counties. Lid.. May 6- 

 November 28. Taken by sweeping herbage about the margins of 

 woodland ponds. Heretofore confused in my collection and probably 

 in many others with L. testaccus ]\Ielsh.. but smaller, comparatively 

 broader with the upper surface much less alutaceous and therefore 

 without the strong greasy aspect of testaccus. The punctures of the 

 thorax are almost invisible, while those of the elytra are distinctly 

 coarser than in testaccus. No abdominal sexual differences are vis- 

 ible in the series of 2/ specimens at hand, though what I take to be 

 the males are more narrow bodied, still less alutaceous and with the 

 disparity between joints 2-3-4 of antennae slightly greater than in 

 the female type. From arenaceiis, described above, this species 

 differs in its paler color, much less robust form, in joints 2. 3 and 4 

 of antennae being less unequal and in the coarser, sparser and much 

 more shallow punctures of elytra.
