The species may be distinguished as follows : 



Body fuscous; head, thorax, feet and base of antennae testaceous; elytra yellow, 

 with base, tip and a median band black. 3 — 4 mm.; Middle and Western 

 States 1. triTasciata. 



Body slender; pubescence fine ; entirely fuscous or piceous ; legs, mouth parts and 

 base of antennas paler. 2.5 — 3.5 mm.; Texas and New Mexico. ...2. fuscilla. 



Body narrow; yellow; with a broad fuscous band on the elytra at the middle. 

 2.5 mm. ; California 3. nubila. 



Body robust; pubescence coarse, fuscous; head, venter, legs and antenna' pah- 

 orange. 1.5 mm.; California - -4. hirsuta. 



1. I*, trifasciata Mels. Pr. Ac. Nat. Sc. Pbila. ii, 318, (Anaspis), Lee. Agassiz 

 L. Sup. 231, (Anthobates). (PL I, fig. 10). 



I have received specimens from Ohio. In Dr. Horn's collection are 

 specimens from the District of Columbia, Dakota and Utah Territory. 

 It does not appear to vary in any respect, and may be readily dis- 

 tinguished from the other species in this genus by the banded elytra. 



2. «». fuscula Lee. Pr. Ac. Nat. Sc. Pbila. xiv, 44. (PL I, fig. 12). 



The few specimens that I have seen agree in every respect with the 

 description; there is a slight variation in size, and some in brightness of 

 color, but none otherwise, that I could discover. The figure shows the 

 appearance of the transverse striation. 



3. 1». nubila Lee. (Anaspis), Pr. Ac. 1859, p. 78. (PL I, fig. 1 1 ). 



Nearly allied to trifasciata in markings, but much more slender in 

 form. The only specimens I have seen are from California, and they 

 present no notable variation. 



4. 1*. hirsute sp. nov. (PL I, fig. 13). 



Readily distinguished from the other species in this genus by the 

 exceedingly small size, the robust form, and the long and unusually coarse 

 pubescence. It is most nearly allied to fuscula. One specimen only ; 

 Coll. Dr. Horn. 



ANASPIS Geoff: 



Scutel rounded, triangular; last dorsal segment not prolonged, sixth 

 ventral not visible; hind tibia slightly thickened, without ridges; fourth 

 joint of anterior and middle tarsi very small, received upon the third 

 which is slightly lobed ; claws dilated at base ; hind femora flat, moder- 

 ate in size ; ■ mesosternum not compressed, finely carinate ; eyes coarsely 

 granulated, with a small emargination ; antennae slightly thickened ex- 

 ternally, not serrate; last joint of maxillary palpi rounded internally, 

 pointed at tip ; transverse strigation very fine. 



In the % , two long slender appendages are seen proceeding from 

 between the fourth and fifth ventral segments; the fourth and fifth and 

 sometimes the others are longitudinally excavated.
