1*. iiigi'ipes u. sp. — Form of luperina, black, shining: elytra dull blue or 

 greenish. Antennae entirely black. Head with few scattered fine punctures. 

 Thorax one-fourth wider than long, sides nearly straight, slightly convergent to 

 base, disc feebly convex, a broad but vague oblique depression each side, the two 

 uniting at middle, surface vaguely punctate. Elytra finely alutaceous, puuctatei 

 smoother near apex. Body beneath black, shining, sparsely punctate. Legs 

 entirely black. Length .20 inch.; 5 mm. 



The male has the segments 2-3-4: of the abdomen gradually 

 shorter, the fifth large, with a broad and deep groove running its 

 entire length. The last dorsal is oval at tip. In the female the 

 segments are of normal form. 



This species is the only one in our fauna with totally black legs. 

 Its resemblance to Haltica bimarginata is so deceptive, that the two 

 individuals in my cabinet were sent with specimens of that species. 



Occurs at Los Angeles, Cal. (D. W. Coquillett). 



SCELrOLiYPERUS Crotch. 



Antennje slender, longer than half the body, second joint shorter 

 than the third. Elytra with distinct edge separating the epipleurse, 

 the latter nearly reaching the apex of the elytra ; last joint of max- 

 illary palpus obtusely conical, slightly longer than the preceding 

 joint, and as wide at base; anterior coxse contiguous; tibi?e without 

 spurs; first joint of hind tarsus nearly as long as the following 

 joints united ; claws broadly appendiculate at base. 



The species of this genus are of graceful form, moderately elon- 

 gate, slightly depressed, the legs rather long. The antennae are 

 similar in the sexes. 



In the males of all the species the last ventral segment is nearly 

 as long as the three preceding joints, the apex very obtuse, the sur- 

 face flattened and slightly concave along the apex. The last ventral 

 of the female is about as long as the two preceding, acutely oval at 

 tip. 



Our species of this genus have been heretofore placed in Lnperus, 

 from which they differ in the absence of tibial spurs. They are 

 larger than Luperus, and of quite different facies, and have always 

 seemed out of place in association with them. 



On an examination of Crotch's type I cannot find that there is 

 any reason why the species subsequently described as Scelida should 

 not be united with it. The character which seems to have attracted 

 Crotch's attention, and which probably induced him to separate the 

 genus, is the presence of a strong tooth on the inner edge of the
