low, i. e., it wants the black transverse line between the frons 

 and clypeus which is present in Armatus (head yellow 7 , front 

 with a transverse black line inferiorly — Hagen). 2. The 

 appendages are clear yellow, brown in the other. 3. The 

 ornamentation appears to agree better throughout with 

 Spoliatus, as described. 4. The oblique lines on side of thorax 

 are isolated. 



The last four rings are colored as follows : 7, sordid olive ; 

 8 and 9, reddish-yellow, clouded with darker shades. The 

 tarsi and tibiae are black, femora blackish beneath, yellowish 

 above ; hind pair with dark line laterally for nearly the whole 

 length, otherwise yellowish on proximal two-thirds, blackish 

 distally. 



Length of abdomen, 45 mm.; of hind wing, 36 mm. 

 The Gomphids are but poorly represented in the collection ; 

 when all are known the number will doubtless be doubled.

This spindle often flies into buildings through open doors 

 and windows ; of course, others do so occasionally, appar- 

 ently by accident ; this one from choice.
