242 THE CANADIAN ENTOMOLOGIST. 



Stiff hairs ; first and second antennal joints piceous, yellowish at bases 

 and apices ; a yellowish crescent bounds base of first joint in front. 

 Between the antennae posteriorly, a narrow transverse yellowish band. 



Vertex elevated behind, rounded, yellowish ; in front, on depressed 

 portion and anterior part of elevated portion, dark fuscous ; longitudinal 

 median furrow and an irregular spot each side, behind, dark fuscous. 



Pronotum as broad as long at base, somewhat narrowed anteriorly, 

 yellowish ; anterior angles rounded, front margin slightly emarginate ; 

 four longitudinal dark fuscous lines.* Lateral carinae yellowish. Below 

 yellowish; on each side, at base of anterior legs, a dark fuscous spot, 

 produced anteriorly along the carina. 



Mesonotum yellowish ; lobes moderately elevated, marked similarly 

 to those of B. 4-punctatiis.\ Sides and beneath yellowish, marked 

 with fuscous. 



Metanotum yellowish, lobes less elevated than those of mesonotum ; 

 marked much as those of B. 4-ptinctatiis ; the two longitudinal lines 

 which unite to form the " U " and heart-shaped markings in the latter, 

 however, approach medially, but do not meet, in this species, giving the 

 appearance of a letter "X" when viewed from a distance. Sides and 

 beneath yellowish, marked with fuscous. 



Abdomen longer than wings, yellowish, a fuscous stripe each side, on 

 dorsum and venter ; the dorsal stripe is separated from the ventral by the 

 lateral suture only ; a longitudinal median fuscous stripe on venter on 

 basal segments. A longitudinal median fuscous line, also, on dorsum of 

 apical segments. All markings of apical segments more extended so as 

 to make these segments almost entirely fuscous. 



Tip of abdomen luteous, clouded with fuscous ; clothed with long 

 dark hairs ; appendages one-half the length of seventh segment, slender, 

 somewhat flattened laterally, divergent on apical half; luteous, clouded 

 with fuscous, clothed with coarse black bristles ; between the appendages 

 below, a short triangular fuscous plate.]: 



Legs short and slender, yellowish, beset with numerous black hairs 



*On the female specimen, the outer lines are nearly interrupted at the transverse 

 furrow. 



fCAN. Ent., XXX , 5, 1898, p. 138. These markings seem to be, in a rough 

 way, continuations of the four longitudinal lines of the pronotum. 



+This seems to be the ventral projection of the sh irt eighth segment.
