crimson spot. Elytra with a wedge shaped longitudinal median 

 vitta. Connexivum black, edged with pale. Beneath : pleural 

 pieces with a lateral crimson spot on each side bordered with black, 

 the intermediate smaller; venter crimson, the base and a connected 

 longitudinal curved vitta on each side, and the genital segment 

 black. Rostrum and femora rufous, tibi?e and tarsi black, the 

 former liueated with pale. Antennae black, basal joint rufous, the 

 next incisures pale. One example of this gaudily marked variety 

 taken in Colorado is in the collection of Prof. Herbert Osborn, and 

 two from Wyoming are in the Museum of Comparative Zoology at 

 Cambridge. 



Var. c. — Deep black ; pronotum, except the base and broad ante- 

 rior disk, wide margins of the propleura, and the disk of the venter 

 crimson red. This is another l)eautiful variety of which I took one 

 specimen at Salida, Colorado, in July, 1900. 



Var. d. — Entirely black or with the costal margin narrowly pale. 

 One specimen from Colorado (Ball), and another from the Cornell 

 University collection taken at Olympia, Wash., by Mr. Kincaid. 



This species in some of its varieties seems to extend aci'oss the 

 entire continent from New England and Quebec to Washington and 

 Vancouver Island, and southward to New Jersey in the east and 

 New Mexico in the west. 



Periling spleudidus Uhler. 



Dr. Uhler records this from California, Texas and Lower Califor- 

 nia, and Prof. Osborn from Colorado. My only specimen, from Los 

 Angeles, California, was kindly presented to me by Mr. Otto Heide- 

 mann. It corresponds very closely with Uhler's description. 



I*erilliis bioculatus Fabr. 



This is the Pentatonia clauda (clanda) of Say. In adopting the 

 Fabrician name I am merely following the lead of the Lethierry 

 and Severin Catalogue. It is a common insect in certain parts of 

 the Rocky Mountain region. My specimens are from Colorado, 

 Nevada (Wickham), Idaho, Montana, New Mexico (Cockerell), 

 and Kansas. Dr. Uhler also records it from California, Utah and 

 Arizona, and Prof. Osborn from Iowa and Oregon. 



There are two quite distinct varieties or styles of marking in this 

 species : the typical bioculatus Fabr., which is black, with the char- 

 acteristic markings varying from pale rufous to crimsou, and the
