 apart.

In the geuus Ceratiuopai^, C. interpreis is hardly congeueric with 

 the other forms, and my C. frontatm is a Maso ; the other species 

 may be separated sis follows : 



1. Cei)halothorax wholly black Iticolor. 



Ce])hal()t]iora.x mostly reddish 2. 



2. Sternum with many roughened, irregular dark marks; black sjx)! (in jiars 



cephalica not truncate behind laticepM. 



Sternum without any such markings ;5. 



3. The black spot covering whole of head, truncate behind iii;;riii*e|>M. 



Black spot only around eyes 4. 



4. Each eye with a black ring NiiniliM. 



Black spot inchiding all tlie eyes iligripalpiM.

 yellci\»-liro\vii. hlackish around eyes. Abdomen whitish or greenish; the sternum 

 brown ; legs pale. Head broad, very much so in the 'S ; in 9 the p. m. e. are 

 less than their diameter a^iart, and a little farther from the p. s. e. ; a. m. e. but 

 little separated, and farther from the a. s. e. ; in the % the s. e. are very much 

 more removed from the m. e. than in the 9- Legs moderate, in the 9 there are 

 long sjiines under tibisp i and ii, each tibia bears above one spine near base and 

 one near tip, and one or two very long fine hairs; -sternum short, sides rounded, 

 obtusely pointed at tij), hind coxie widely separated; the epigynum shows a 

 transverse reddish area, in the middle a small cavity divided by a broad septum,
