aligned in rows) ; in I. leucomelas the punctures in the yellowish areas 

 are clearly aligned in rows continuous mth those on the dark markings.

Cryptoceplialus leucomelas trisignatus, new subspecies 



Figure 103 



Head: Creamy yellow; vertex, antennal insertions, clypeus, and 

 labrum reddish. 



Pronotum: Background color light orange. Dark markings red to 

 deep red, consisting of four longitudinal, complete, subparallel stripes, 

 rather sharply delimited and distinctly separated; median two nearly 

 straight sided, each just wider than median light stripe they enclose; 

 lateral two stripes distinctly wider than inner two, widest near middle. 



Elytra: Background color light orange. Dark markings and punc- 

 tures red to deep red, each elytron with markings as follows : behind 

 base with a slightly diagonal band, extending from suture laterally to 

 extreme side, this usually continuous, sometimes disconnected near 

 humerus; with two spots at apex, one centered before apex of third 

 stria, other centered before apex of seventh stria; usually also with a 

 more or less distinct, small spot at apex of first stria. 



Ventral surface: Ventral surface and legs nearly uniformly reddish. 

 With yellow as follows: on prosternum, on front coxae, on meso- 

 sternum and mesepimeron, on basal median portion of first abdominal 

 segment, and sometimes at sides of abdominal segments. Fifth ab- 

 dominal segment of female with a large, oval, deep depression at 

 center. 



Length: 4.5 to 4.7 mm. 



Type data. — All three specimens are females from Minnesota. The 

 holotype bears the data Red Falls, Minnesota, Stoner, July 31-1911"; 

 it is USNM type number 69242. One paratype was taken at Hanley 

 Falls, Minnesota, by Stoner on August 1, 1911, the other at Olmstead 

 County, Minnesota, on "6.97" by C. N. Ainslie and is from the col- 

 lection of F. Knab. All type specimens are in the U.S. National 

 Museum. 



Discussion. — This subspecies differs from I. leucomelas in that the 

 elytra bear no submedian band and no lateral spots; these are present
