CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 27 



Pronotum: Background color light orange or creamy yellow, dark 

 markings black, in general not sharply dehmited, margins often brown 

 to reddish, orange or yellowish areas at sides and near apex often 

 speckled with reddish or brownish. Dark markings as follows: On 

 most of disk and basally on each side; laterally each side a small si)ot; 

 discal markings narrowly touching basal spots (holotype) or not 

 (allotype). Punctation dual, smaller punctures minute, moderate in 

 density, larger punctures small, rather sparse. 



Elytra: Background color Hght orange, dark markings black, 

 sharply delimited. Markings of each elytron as follows: on sutural 

 stria; on second, fourth, and sixth intervals, vittae on second and 

 fourth intervals joined at base (holotype) or not (allotype), weakly 

 joined at apex (allotype) or not (holotype), vitta on sixth interval 

 somewhat expanded laterally at humerus; seventh stria and lateral 

 marghi beyond middle black. Each elytron with seven striae and a 

 short series behind humerus; punctures rather small, usually forming 

 even rows, rows five and six uneven or a Httle confused, latter more 

 often so; punctures distinctly smaller toward apex; inner and outer 

 rows distinct and usually meeting at apex. 



Ventral surfaces : Prosternum and mesosternum light orange or yel- 

 lowish, former clouded with brownish at side; metasternum yellowish 

 and clouded with brownish or blackish, especially at sides; metepi- 

 sternum black; abdomen predominantly yellowish basally at center, 

 at apex, and at sides, remainder clouded with brownish or blackish; 

 fernora with anterior face clouded with brownish, margins pre- 

 dominantly yellowish, posterior face brownish or black throughout; 

 tibiae with outer margin brown, darkest at apex, imier margin yellow- 

 ish, lightest at base; tarsi brown. Anterior margin of prosternum 

 produced ventrally into a distinct, pointed lobe in male, lobe less 

 produced in female. Fifth abdominal segment somewhat depressed 

 at center in male, or deeply depressed into an oval fovea in female. 

 Pygidium with distinct, rather dense punctures, black basally, yellow- 

 ish to light orange apically. 



Length: 4.7 to 5.0 mm. 



Type data. — The description is from two individuals taken at 

 Monterey, California, on July 30, 1927, by D. H. Blake. The male 

 holotype (type number 69252) and the allotype are in the U.S. 

 National Museum. 



Discussion.— The external differences exhibited by this subspecies 

 and two specimens of C. alternans alternans Suffrian from Mexico in 

 the USNM collection are primarily a matter of coloration. In a. 

 alternans, the discal and lateral dark markings of the pronotum 

 broadly join; in a. jungovittatus they do not or just narrowly jom.
