Cryptocephalus pseudomaccus, new species 



Figures 108, 132 



General: Body 1.7 to 1.8 times as long as wide; dorsal surface 

 shining, without pubescence, most of ventral surface with short and 

 sparse, whitish pubescence. 



Head : Creamy yellow, vertex, clypeus, labrum, and antennal inser- 

 tions reddish (in one specimen entire head more or less reddish) ; front 

 with moderate-sized punctures; clypeus rather sharply delimited at 

 base and sides, distinctly broadest apically, rather concave. Antennae 

 about three-fourths length of body in male or over half as long as 

 body in female; reddish, basal segments more or less orange. 



Pronotum: Background color creamy yellow to light orange; wdth 

 four broad, dark reddish, sharply delimited, longitudinal vittae, also, 

 a rather small, dark reddish, isolated spot present on each side; vittae 

 extending from base to apex, inner margins of two median vittae 

 nearly parallel, other margins outwardly arcuate. Punctation dual, 

 smaller jjunctures minute, not dense, larger punctures small to moder- 

 ate in size and a little coarse. 



Elytra: Background color creamy yellow to light orange, punctures 

 and markings dark reddish. Dark markings on each elytron as follows: 

 a moderate-sized spot on humerus, a smaU spot below and a Uttle 

 beliind humerus; a small spot behind humerus (much reduced in 

 allotype and paratype) ; a small spot behind the preceding; a small 

 spot near base of third interval (much reduced in paratype, absent in 

 allotype), a moderate-sized to small spot at suture before middle; 

 behind middle a large, wide, transverse band, this attaining fifth row 

 of punctures, lateral to this a moderate-sized spot attaining margin; 

 at apex two moderate-sized spots, outer smaller. Each elytron with 

 first five rows of punctures fairly even and distinct, rows at side 

 (except last) reduced and confused, seven or eight rows may be 

 counted; punctures moderate in size, not close, smaller to apex as 

 usual; inner and outer rows distinct and usually clearly meeting 

 at apex. 



Ventral surface: Most of ventral surface and legs orange or red. 

 Following parts yellowish to orange: prosternum at center, anterior 

 coxae, mesosternvim and side pieces, first abdominal segment at center, 

 each segment at side, sometimes also fifth abdominal segment at center. 

 Anterior margin of prosternum normal to feebly produced into an 

 arcuate lobe in male or not produced in female. Fifth abdominal seg-
