CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 79 



merit at center with a deep, oval pit in female or fiftli segment feebly 

 depressed at center in male. Pygidium longitudinally carinate at cen- 

 ter, red to orange at base and on carina, with yellowish spots on each 

 side near apex. 



Length: 4.0 to 4.2 mm. 



Type data.— This description is from three individuals taken at 

 Globe, Arizona, by Parker. The holotype (male, in CaUfornia Academy 

 of Sciences) was taken on April 16, 1934 on Acacia greggii, the allotype 

 (also in California Academy of Sciences) bears the follo\\ing data 

 "July V-11-1934"; a male paratype was taken on April 16, 1934 on 

 Acacia greggii and is in the USNM collection. 



Discussion. — The species is quite similar to maccus and can be 

 distinguished in the basis of the submedian elytral spot. In maccus, 

 this spot is undulate and attains the lateral margin; in pseudomaccus, 

 it is not undulate and does not attain the lateral margin.

 Cryptocephalus pubicollis Linell, 1897, p. 480. 



Pronotum: With silvery pubescence; black throughout; punctation 

 dual, larger punctures moderate in size, dense, and distinctly impressed. 



Elytra: Dark brown to black, each elytron with orange to reddish 

 humeral marking extending from base of second stria diagonally to 

 past middle at side. With nine rows of punctures, rows six and seven 

 nearly always confused or one or the other much reduced; punctures 

 as large, dense as usual, much finer at elytral apex; inner and outer 

 rows of punctures more or less distinct at apex, usually not clearly 

 meeting. 



Prosternum: Anterior margin in male with a large sharp spine 

 directed diagonally backward; anterior margin in female produced 

 into a broad, sometimes pointed lobe. 



Length: 5.0 to 6.0 mm. 



Discussion. — All three members of the type series (two females, 

 one male) are in the U.S. National Museum and bear type number 

 1308 (not 1307 as cited in the original description); these specimens 

 were taken in Arizona by Morrison. The single male I hereby designate 

 as the lectotype and have so labeled it. 



Distribution. — All 14 specimens examined are from Arizona.

Pronotum: Nearly uniformly dark brown to black; punctation dual, 

 larger punctures small to moderate and rather coarse.
