that is, the lateral margin is straight from the base of the tubercle to 

 the apex while in consanguinea the lateral margin is narrowing 

 obliquely from the tubercle to the apex. 



Lema arizonae new species. 



Very near L. texana Cr. in form and color, except mouth parts, meso- 

 sternum, side pieces of metasternum and legs black. Head sparsely punctate, 

 frontal tubercles obliterated ; median groove short and not very deep, ter- 

 minating in a rather deep fovea. Prothorax in sculpture and form as in 

 texana Cr. Scutellum slightly subquadrate and emarginate at apex. Elytra 

 blue with ten regular rows of rather coarse punctures, the punctures a little 

 smaller towards apex ; intervals smooth. Abdomen finely and densely punctate ; 

 clothed with short, greyish-white hairs ; posterior femora extending to the 

 apex of the third ventral segment and slightly more incrassate than in texana 

 Cr. Length 5.25 mm. 



Huachuca Mts., Arizona. 



Lema longipennis, Linell, to which this species also seems to be 

 allied, has the underside of body and head black and an elongate 

 scutellum with the apex rounded. 



Lema equestris Lac. 



Lacordaire's description of this Mexican species agrees fairly with 

 those specimens of the variable L. balteata Lee, which have the pro- 

 thorax red, to which I have already called attention in Science Bull. 

 Mus, Brookl. Inst. Arts and Sciences, vol. I, p. 169. L. balteata has 

 the head, prothorax, legs and underside black, abdomen flavous, elytra 

 blue with a large, yellowish or reddish-yellow, transverse fascia as in 

 L. solani, the lateral margin is blue but always interrupted by the 

 transverse fascia. The transverse fascia is generally broad but I 

 have specimens with very narrow fascia and one specimen with an 

 indistinct fascia on one side and without fascia on the other side. A 

 number of my specimens have in addition to the transverse fascia 

 either one or two yellow subapical spots on each elytron. These sub- 

 apical spots are of variable size and are coalescent in some specimens, 

 forming a slightly arcuate subapical fascia. The specimens with red 

 prothorax, of which I have taken only a very few, generally have the 

 subapical fascia distinct. In about three of my specimens the pro- 

 thorax is black with apex and base more or less red, these are inter- 

 mediate between those with red and black prothorax.
