vertex orange brown or dull red, obscurely marked with black 

 to a varying degree; ocelli with their opposed sides- very nar- 

 rowly black ; a short transverse line through the median ocell- 

 us, with a more or less anterior fork on each side or wdth a 

 transverse line near the f rons ; on either side a black bar be- 

 tween the antenna and eye ; a thread of black, not always de- 

 scernible. from behind each lateral ocellus to the eye; oc- 

 cipital crest black. Antenna obscure yellow, first joint brown 

 or black, second joint darker at apex, third joint Avith basal 

 half pale, and the apical half darker, with a submedian black 

 or brown ring. Profile similar to figure 65. 



Prothorax dull yellow, front lobe bordered with black in 

 front ; middle lobe brown in the middle and with an indefinite 

 brown area on either side ; hind lobe black, posterior margin 

 on either side, but not reaching the extreme lateral margin, 

 yellow^ Propleuron bright yellow. 



Thorax very similar to that of ictcricuui ; the large dark 

 area on the mesepisternum, between the pale line adjoining 

 the middorsal carina and the pale antehumeral line, is better 

 developed than in ictcricuui, covering the entire area between 

 the two pale stripes, reddish brown along its inner border, 

 but developing into very dark brown or black along the entire 

 outer border ; on the other hand, the dark on the mesepimeron, 

 as compared with ictericum, is slightly shortened above and is 

 interrupted below a short distance above the mesinfraepister- 

 num ; the brown on the metepisternum is variable, sometimes 

 interrupted ; the small superior spot on the metepimeron is 

 always present. 



The description of abdominal segments 1-7 and 9 and 10 

 of ictericitui will apply equally well to inclaiiiinuii, except that 

 possibly in the latter the pale colors are lighter and brighter 

 yellow, and 2 lacks the median basal pale spot ; but 8, which is
