DESCRIPTION 



OF A 



NEW SPECIES OF CALOSOMA. 



BY 



J. L. LECONTZ, M.D. 



Calosorna simplex n. spec. Black, subopake. Head and pro- 

 thorax finely rugose and punctulate, the latter more than twice as 

 wide as long- ; sides strongly margined, rounded in front, oblique 

 behind, more widely refiexed towards the base ; base bisinuate, 

 broadly rounded at the middle, hind angles distinctly prolonged, 

 broadly rounded ; basal impressions large and deep ; dorsal line 

 fine. Elytra slightly wider than the prothorax, oblong, oval, con- 

 vex towards the sides, which are narrowly margined towards the 

 base and more widely so along the sides ; near the base are seen 

 four small acute teeth, as in our allied species ; striae not impress- 

 ed, composed of extremely fine punctures ; the punctures of the 

 three dorsal rows are also small and not conspicuous ; interspaces 

 alutaceous not distinctly rugose. Tibiae straight. 



Length 20.5 mm. Middle California, one male. 



COLLECTING INSECTS IN WINTER. 



Before the last cold days I collected on a fine afternoon very many coleop- 

 tera at the foot of a hill, among which were about 50 Platynw lutidentus— 

 more than I captured in six years all together, some other common Platynus, 

 as extenslcoll'is, decants, mdana/rius, cupripennL?, octopunctatics, placidus stri- 

 gheoliis, some Oodes, Anisodaetylus, Scydtnaenldae, Staphilinidae, etc. 



The greater part were sitting on the underside of the stones and were mov- 

 ing away very slowly, so that the capture is more easy than during spring 

 and autumn.
