PSYCHE. 



57 



tex of smitliii. Clypeus no longer than 

 broad, sides very slightly converging to the 

 subtruncate apex. Ledges over antennal 

 cavities strongly bent towards clypeus. 

 Pronotum aciculate except within anterior 

 lateral angles, where there are some faint 

 brownish spots. Elytra whitisli opaque, 

 very strongly but somewhat sparsely seti- 

 gerous punctate, the hairs on base of clavus 

 weak and white. 



Color sordid yellowish, tinged with green- 

 ish on pronotum posteriorly, scutel, costa 

 at base, and hind tibiae. 



Last ventral segment twice the length of 

 the preceding, hind margin broadly rounded, 

 with a large median notch which is acute at 

 apex and reaches nearly a third the length 

 of the segment. 



Described from a single fuinale in the 

 Herbert H. Smith collection, taken at 

 Chapada, Biazil, in April. This may 

 be near d/'v/sa St;il, which I have not 

 seen, but it does not at all fit the 

 description of that species. 



Macrofsh cah'forniciis n. sp. — Female. 

 Length 5 mm. Far larger and stouter than 

 robnstiif. Head little narrower than pro- 

 notum. Vertex very slightly longer on mid- 

 dle than next eye. Clypeus slightly longer 

 than broad at base, sides gently converging 

 towards the truncate apex. Ledges over 

 antennal grooves nearly in a straight line. 

 Pronotum aciculate except just within lateral 

 carinae. Elytra thick, opaque, with a num- 

 ber of supernumerary veinlets towards the 

 apex; hairs on elytra not strong anywhere, 

 those on clavus weak and white, those on 

 corium sparse and mostly black. 



Head, all below, and elytra largely, pale 

 straw color. Pronotum rufescent. A nar- 

 row area on clavus, adjoining inner angle 

 usually deep reddish. Elytra often more or 

 less tinged with reddish toward base. Dor- 

 sal segments mostly with discs black. 



Last ventral segment little longer than 

 preceding, broadly deeply emarginate, bot- 

 tom of the emarginatiou inclining to sub- 

 rectangular. 



Male. Length 4.75. Front above, vertex 

 except narrow basal margin, pronotum and 

 extreme base of scutel. black to piceous. 

 Elytra exccjit apical ai'eoles suffused with 

 bright reddish. Last ventral segment over 

 twice the length of preceding segment, hind 

 margin broadly rounded and with a minute 

 median slit. 



Desciibed from one male and a num- 

 ber of females in the National Museiun 

 collection, taken by Mr. Koebele in 

 Placer Co.. Calif., during September 

 and October. One female partakes 

 somewhat of the male characters in 

 having a spot on front above and ante- 

 1 ior margin of pionotum, blackened. 

 This is the tnost highly colored ot 

 known North American species. 



Mucrofsis magniis n. sp. — Female. 

 Length 5.5 nnii . Near to catifornicus, but 

 differing from it as follows: Larger and 

 stouter. Pronotum without distinct super- 

 numerary veins. Whole insect darker 

 throughout. Verte.x on either side in front, 

 and basal margin of scutel, piceous or black. 

 The dark color on scutel shading through 

 ferruginous to light yellow at apex. Wings 

 dark fuliginous at base. 



Last ventral segment of female twice the 

 leTigth of preceding, hind margin trisinuate, 

 the three sinuosities of equal depth, the 

 lateral broad, the median narrow and acute. 



Described from a single female in the 

 National INIuseum collection, taken in 

 Los Angeles Co., Cab, by Mr. Coquil- 

 lett. It is very near to californicus 

 but easily separated by the size and 

 genital characters.
