NORTH AMERICAN MALACHIIDAE 
The type is a male taken at Truckee by Wickham, The fe- 
males were all taken by the writer at Lake Tahoe. In none of the 
specimens does the red color of the elytral tips show any tendency 
to extend forward along the suture. 
Tanaops dubitans new species 
Very similar to the last. The head seems to be a little less elongate and the 
thorax is obviously more transverse, and is broadly red at sides. The abdomen 
is more reddish at base, the basal segment being entirely red in the male, and 
blackish at sides only in the female; second segment dusky at sides in the male. 
It is possible these differences may disappear in a larger series. 
California: Sylvania, Sonoma County. One pair sent me 
many years ago as longiceps by Mr. Ricksecker. 
Tanaops mimus new species 
Moderately elongate, shining, finely, rather sparsely pale pubescent and 
nigro-setose, finely, sparsely punctulate throughout. Head black, mouth 
pale; thorax rufo- testaceous with variable and irregular discal blackish cloud, 
which may be entirely wanting. Elytra entirely dark greenish bronze. Body 
beneath and legs, black, abdomen entirely yellow in the male, in the female 
yellow with terminal segment black, or varied with black throughout. An- 
tennae black, pale at base, fully half as long as the body and narrowly serrate 
in the male, with all joints elongate, the outer ones twice as long as wide; 
a little shorter and less serrate in the female. Head about as long as wide, a 
little narrower than the thorax, the latter a little wider than long, the sides 
broadly arcuate, nearly straight and parallel at middle. Elytra gradually 
widened behind, surface with little irregularities which give the appearance of 
being finely tuberculate. Length 2.5 to 3 mm. 
Utah: Nephi (type d'), collected by Wickham. Colorado: 
Glenwood Springs, (Fenyes). 
Very similar in appearance to Attains nigripes Horn, which 
name had been attached to my specimens. The latter is, how- 
ever, entirely black beneath and is supposedly a true Attains. 
Tanaops coelestinus Gorham, Biol. Centr.-Amer., Coleopt., iii, 2, p. 320, 
(1886). 
Black, moderately shining, elytra with distinct bluish or greenish luster, 
thorax typically with a reddish spot at the hind angles, often entirely black, 
more rarely with sides red. Head moderately wide. Antennae not strongly 
serrate in the male, feebly so in the female. Thorax a little wider than long, 
not widened behind, sides rather straight. Elytra with the usual vestiture, 
sparsely, finely punctulate and minutely, sparsely tuberculate. Abdomen 
black in the female; in the male the fourth and fifth segments are predominantly 
yellow, the fourth more or less blackish at sides. Legs black, front and middle 
trochanters pale, front thighs sometimes pale beneath. Length 2.75 to 3 mm.
