f. 4), there Ijeing present three or fonr rather heavy aj)ieal spines liesides a nnnilier 

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



S. Tenth abdominal sternite more deeply sinuate than in separattis. Harj)e 

 similar to that of lugens (while the harpe oi si'paratus resembles that oi geminus), 

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

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

 shorter than in separatus. 



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

 black. — Food : Salvia. 



Two broods, larva in June and October.

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

 tarsal armature." This is incorrect, inasmuch as, in ereniit/ts, the first protarsal 

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

S ? . The " lugens " with which Neumoegen compares separatus in tlie 

 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 remarkal)le that .separatus and eremitoides dift'er in the harpe exactly 

 in the same way as do higens 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 

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

 The antennae of the S are very stout. Foretibia aud first protarsal segment see 

 PI. LXIV. f. 4. 



S. Tenth abdominal sternite broader than in ^e/««««s, feebly sinuate. Har])e 

 much 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 eremitus, the 

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



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

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

 rounded, more smooth, without lateral grooves. 



Larva and jiujia not known. 



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