252 GEO. n. HORN, M. D. 



3. — Basal third of hinder femora opaque and finely punctured SublfCVis* 



Basal tliird shining and with very few punctures 5. 



6. — Legs piceous, form more oval and convex ellipliciiN. 



Legs bicolored, form more oblong, less convex calif'oriii<*iis. 



4. — Punctures of surface fine and equal ^Iiibor. 



Punctures coarser and unequal uiixtiiM. 



T. sf riolatiis. — Legs entirely testaceous except at base of femora. Last 

 ventral segment without crest. 



T. Sllbliicvis. — With this species should be placed guadristriatus, Horn. 



T. glabf^r. — The punctures of the surface are very fine and equal, and do 

 not dim tlie gloss of the surface. 



T. mixtiis. — The surface has a. resemblance to that of Dineutus viifatux. 

 Species other than glaber and niixtus often have a fine raised line on the last 

 ventral segment, but no spiniform crest. 



T. ellipf i<^us, occurs at times with legs more or less bicolored, but its 

 form more ar&ed and more obtuse at each end will at once distinguish it. 



T. lateralis.— Dr. Zimmerman (Trans. Am. Ent. Soc, 1869, p. 249), thinks 

 that Say's name {nimbatus), should be retained, inasmuch as the two species do 

 not appear to be identical. This must, however, be left for further determi- 

 nation. Herbst's lateralis is apparently an erroneous determination, and is 

 striolatus, Lee. (G. II. H). 



Anthrenus claviger, Er., must be included in our lists. It may be 

 known by its five-jointed antennae the club of which is formed of one 

 long joint. It is usually confounded with musseorum, Linn , {castanese, 

 Mels.), in cabinets. (g. h. h.) 



A. scrophularix, Linn., has also been reported from the State of 

 New York, where the larva has been found to be very injurious to 

 carpeting in houses, (Lee, Proc. Acad., 1876, p. 195). 



Aghnus hrunneus, (Gyll.), another European insect has been col- 

 lected in Missouri; Ulke. 



P//anisia opaca, Sol., and ZopJwhax morw, Fab., have occurred 

 within our territory, the former in Texas, and the latter in Florida, 

 abundantly.
