Diagnostic characters. — Inculta is a distinct species, with a shorter, 

 more robust form, distinctly transverse prothorax (female), and 

 feebly subasperate (subgranular) punctuation. The sides of the 

 prothorax are scarcely at all sinuate before the basal angles — in some 

 specimens not in the least and in others feebly so; the basal angles 

 are obtuse, distinct, and with the appearance of being just a little 

 prominent ; the lateral bead is distinctly entire. 



I do not believe inculta to be a synonym of scahripennis. The type 

 of the latter is a female and was taken at Fort Tejon. Doctor Horn 

 made so many wrong determinations in Elcodes that I can not be- 

 lieve him right in this instance. 



Mr. Blanchard has very carefully compared a female inculta (which 

 is before me) with the female type of scahripennis. His com- 

 ments are as follows: " Shorter and less convex than the type of 

 scahnpennis, thorax much broader. It seems nearer inculta of which 

 the type is a male with base of the prothorax more constricted." 

 Later and in another sending I submitted a male specimen, which 

 he unhesitatingly pronounced inculta. I sent the female first inten- 

 tionally with a request to compare it with scah?%pennis. 



The form of the thorax in snowH (male and female) and the male 

 of inculta is quite similar, but the apical angles in the latter are 

 more acute and prominent, and in every example studied the sides 

 are just the least subsinuate behind the angles so as to give them an 

 appearance of having a slight tendency to eversion. 



The form of the prothorax should readily separate inculta from 

 hornii, neotomce and couj^ohrina — none have it so transverse in the 

 female, nor the sides so feebly sinuate at base as a constant character. 

 In consohrina the apical angles are as prominent, but scarcely as 

 acute, the sides may be feebly sinuate behind the apical angles and 

 more or less strongly sinuate before the base. 



General observations. — The mentum is moderate in size, sometimes 

 rather small in the male, subtruncate and parabolically rounded; 

 surface feebly convex, scarcely subfoveate laterally, finely punctate, 

 the punctures not distinctly defined nor noticeably setigerous. 



The jDrosternum is moderately prominent ventralh' with the coxfp, 

 moderately arcuate antero-posteriorly between the coxae and usually 

 with a small mucro behind at middle; at other times more feebly 

 arcuate and more or less vertical behind, Avith the angle mucroid. 



The mesosternum is arcuately declivous and more or less deeply 

 and not broadly concave. 



The metasternum laterally between the coxee is as long as the width 

 of a mesotibia at apex. 



The abdominal intercoxal salient is subquadrate (male) or slightly 

 transverse (female) and a little (male) to a fourth (female) of its 

 own width broader than the metasternal process.
