f. 4), tliere being present three or fonr rather heavj' a])ical spines liesides a nnnilier 

 of smaller ones, situated on the outer surface from apex to near base. 



c?. Tenth abdominal steruite more deeply siuuate than in separatus. Harpe 

 similar to that of ln</ens (while the harpe o? .trparatiis resembles that oi gemiims), 

 but narrower, ventrally less rounded-dilated, the tooth shorter and less curved 

 (Fl. XXXVI. f. 17, dorsal view). Penis-sheatli as in geminus, the apical process 

 shorter than in scparatns. 



Larva (accord, to Strecker) pale green, with seven white side-bauds ; horn 

 black. — Food : Sulcia. 



Two broods, larva in June and October. 



Hob. Kansas ; New Mexico ; Texas ; probably in all the Southern States.

 N. Mexico, near Hot Springs, Las Vegas, TOUO ft., July '82 (Snow). 



Prof. Smith, I.e., states that the species agrees with eremitiis " in tibial and 

 tarsal armature." This is incorrect, inasmuch as, in cremitiis, the tirst protarsal 

 segment is shorter, the spines are longer, and the midtibia is armed with spines.

S ? . The " lugena " with which Neumoegen compares separatus in the 

 description of the latter is eremitoides. The differences pointed out by him are 

 just those which separate eremitoides from the present species, which is doubtless 

 correctly identified, though we have not seen the type. Snow got both species in 

 New Mexico. 



It is very remarkable that separatus and eremitoides differ in the harpe exactly 

 ill the same way as do hiqeiis and geminus. 



In all the specimens we have seen the collar is conspicuously marked with 

 a yellow marginal spot at each side ; these spots are barely vestigial in the allied 

 sjiecies ; no mention has been made of them in the description of separatus. 

 The antennae of the c? are very stout. Foretibia and first protarsal segment see 

 PI. LXIV. f. 4. 



S. Tenth abdominal stcrnite broader than in geminus, feebly sinuate. Harpe 

 mnch shorter than in geminus but of nearly the same shape, more curved upwards, 

 the dorsal edge sharply dentate (PI. XXXVI. f. 16). The rounded apical process a 

 little more prominent than in geminus and eremitoides, nearly as in eremifus, the 

 tooth a little more proximal than in the former two species. 



?. Vaginal plate (PI. XX. f. 14) almost as in geminus, but the sides of the 

 distal part less elevated, the cone which bears the vaginal orifice more evenly 

 ronnded, more smooth, without lateral grooves. 



Larva and piijja not known. 



Ilab. Colorado ; New Mexico ; Mexico ; probably of wider distribution.
