AMERICAN MUTILLID.E. 241 



apical margins of the segments with silvery puhescence, that on second dorsal 

 broken into three spots, that on dorsals 3-5 spreading over the entire segments 

 medially; head subquad rate, about as wide as thorax, coarsely and confluently 

 punctured ; postero-lateral angles rounded ; first joint of flagelluni about as long 

 as two following united ; thorax pyriforni, covered above with large punctures; 

 first segment with large punctures, the carina bideutate ; second dorsal segment 

 with elongate punctures, those at base coarser and rounder ; j)ygidiuni longitudi- 

 nally striated. Length 11 mm. 



Colorado. One specimen. This species combines the character- 

 istics of the preceding species, 4-guttata to caneo, and the following 

 five species. The head is intermediate in size between the two 

 aggregations of species mentioned, and in the pyriform thorax it 

 agrees with sccevola, etc. 



The following five species have the head wider than thorax, the 

 latter more exactly pyriform, and the first segment is more nodose 

 than in ferrugata and its allies.

9 .^Ferruginous, sparsely clothed with pale, erect hairs ; second dorsal with two 

 pale spots, fuscous or black at base and apex, dorsals 4 and 5 covered with silvery 

 puhescence, segments 3 and following black, second and third ventrals fringed 

 with silvery pubescence; legs blackish or brown ; head subquadrate, wider than 

 thorax, strongly and closely punctured, the postero-lateral angles bearing a 

 short carina running inwardly; thorax pyriform, rugosely punctured, tending 

 to reticulate posteriorly; carina of first ventral segment entire, truncate; second 

 dorsal with elongate punctures, the second ventral with the punctures tolerably 

 strong and widely separated ; pygidium longitudinally striated. Length 10 mm. 



Ma.-;sachusetts; New Jer.sey ; Pennsylvania. This species will be 

 found in several collections under sccevola; the latter has not, as yet, 

 been found in the Eastern States.
