NEW COLEOPTERA FROM THE SOUTH - WEST.— IV. 



BY H. C. FALL, PASADENA, CALIF. 



The greater number of species made known in this, the fourth paper* 

 of miscellaneous descriptions of Coleoptera from the South-west, are from 

 the Peninsula of Lower California. These descriptions were written some 

 eight or nine years ago, and are based upon material received through 

 Mr. Chas. Fuchs, from the California Academy of Sciences. It was the 

 intention, when sufficient material had been obtained, to publish a third 

 supplement to the " Coleoptera of Baja California," by Dr. Horn, but the 

 source of supply gave out very soon after the receipt of the first install- 

 ment. One of the species described at that time — Saxitiis Hor?iii — was 

 shortly after received from San Diego, Cal., and this name appears in my 

 List of the Coleoptera of Southern California, the description, however, 

 being accidentally omitted. It is high time that this No men nudum was 

 made good, and it is thought best to present also the description of the 

 other new species written at the same time. The opportunity is taken to 

 add a few other new species collected by Mr. Beyer in the same region, 

 together with two or three more from various sources. 



Canthydrus levis, n. sp. — Rather broadly oval, more narrowed 

 behind, colour yellowish-testaceous, elytra darker, upper surface polished 

 throughout. Head impunctate, thorax subimpunctate, except for a line of 

 rather fine punctures along the front margin, and a somewhat numerous 

 group of coarser but feebly impressed punctures irregularly placed in the 

 median basal region. Elytra with intermixed fine and somewhat coarser, 

 feebly impressed punctures, which are slightly better defined in two discal 

 lines bearing fine short hairs. Beneath almost impunctate, except the 

 sternal plates, which are strongly, rather coarsely punctate, each puncture 

 bearing a posteriorly-directed bristle-like hair. The prosternum is broadly 

 rounded anteriorly, and bears at the middle, on either side of the central 

 line, one long and several much shorter spiniform bristles, set subtrans- 

 versely. The transverse lines of punctures of the abdominal segments are 

 almost wanting. 



Length, 2 mm. One example, San Jose del Cabo. Type in the 



collection of the California Academy. 



This species is very easily distinguishable from any previously 

 described from our fauna, and I am unable to identify it with any of the 

 Mexican forms mentioned in Sharp's Monograph.
