1912] North American Scoliine 315 
Triscolia fervida (Burmeister). 
Scolia fervida Burm., Abh. Naturf. Ges. Halle, I, p. 4, 1853, p. 20, n. 12 9 
Am.: Texas, Mexico. 
The location of the type is unknown to the writer. 
Burmeister has recorded this insect as from 14 to 16 lines long, 
while Saussure and Sichel have recorded the length as from 35 to 40 mm. 
The females which the writer has examined vary in size from 20 to 28 
mm. in length and the males from 15 to 21 mm. 
The body of this species is black except the segments of the abdomen 
behind the second. These are dark reddish brown with very little 
variation. The wings are uniformly fuliginous with intense metallic 
reflections, green at some angles, deep blue at some and purplish at 
others. The nervures are black. This species is one of the largest in 
this subfamily. 
The typical examples are described by Burmeister as all black 
except the part of the abdomen beyond the second segment which he 
describes as red, red brown, or rufous. Saussure and Sichel describe a 
variation in which the posterior part of the second segment is also rufous. 
The specimens that the writer has personally examined agree quite 
well with Burmeister’s typical description and also agree with a good 
figure published in Vol. II of Cameron’s Biologia, plate 12, figure 17, 
except that the posterior part of the second segment was always reddish 
brown or rufous, more evident on its under surface, and the parts 
described as black by Burmeister have a slight tendency when observed 
under the lens toward a rufous tinge. The edge of the clypeus, emargin- 
ation of the eyes, edges of the mandibles, the legs especially the end 
segments and the spines are usually quite rufous. The edges of the 
segments of the abdomen described as rufous have a tendency toward 
darker, sometimes blackish coloring. 
Burmeister records the habitat of this species as Mexico: 
Saussure and Sichel as: Mexico and Texas. The writer has seen 
specimens from Mexico, Arizona, Texas and New Mexico.
