piceous, sutiiral line; anterior and middle legs and hind tibiae and tarsi 

 flavous; basal five segments of antennae and maxillary palpi flavous. 

 Body densely covered with fine, recumbent, fiavocinereous pubescence.

 arcuate, midbasal lobe short, rounded. Scutellum small, triangular. 

 Elytra slightly more than twice as long as broad (1.35 by 0.65 mm), 

 sides subparallel, apices individually rounded. Posterior tibiae with 

 two equal oblique ridges extending halfway across outer face ; posterior 

 basitarsus with two oblique ridges, second segment with one oblique 

 ridge. Anal style but twice as long as apical ventral segment, stout,

MORDELLISTENA VARIETAS, new species 



Figure 28, g, k 



From signaticollis Quedenfeldt (1886, p. 125) this species may easily 

 be separated by the black color of the elytra and the different shape 

 of the distal segment of the maxillary palpus. 



Length: 2.8 mm; including anal style, 3.9 mm. Elongate-oval, 

 sides narrowly rounded; head flavous, vertex with a rounded fuscous 

 spot almost reaching eyes and occiput ; pronotum flavous with a median 

 fuscopiceous stripe, broadest at base and embracing the entire mid- 

 basal lobe; antennae flavous at base, piceous at apex, intermediate 

 segments successively darker toward distal end; sternal sclerites of 

 thorax and elytra wholly piceous; maxillary palpi, legs, and ventral 

 abdominal segments castaneous. Body densely covered with fine 

 recumbent pubescence, generally partaking of ground color.
