metaparameres are very much narrower, and almost perfectly 

 crescent-shaped, the internal basal dilation being practically 

 obsolete (PI. VIII. fig. 14). 



It is unfortunate that we have not got any record of the geni- 

 talia of Pyragropsis tristani Bor., type of that genus, since it may 

 turn out that we may yet keep Pyragropsis and Propyragra dis- 

 tinct, one for the Pyragra and P. paraguayensis type of metapara- 

 meres, the other for the P. thoracica type. 



It will be interesting, too, to see the form of the virga in this 

 group. 



In Pyragra fuscata Serv., Pyragropsis thoracica Serv., and 

 P. paraguayensis Bor., the manubrium is short and transverse, well 

 rounded, almost semi-circular. 



Sub-family 8. Blandicin^e. 



This imperfectly known sub-family is provisionally erected for 

 the unique specimen in the Vienna Hof museum, which I have 

 described under the name Blandcx solvcndus ; it is simply labelled 

 " South Africa." The relationship of this curious creature is still 

 uncertain ; there is something Pygidicranine in its appearance, 

 especially in the style of coloration. The antenna; recall those of 

 Anatsdia, but the keels of the femora are obsolete, or almost, as 

 also those of the elytra ; the structure of the sternum agrees with 

 that of Anatselia and Challia. I can detect no combs on the 

 mesosternum, so it is a truly apterous species, although the elytra 

 are free. 



The genitalia are curious, and do not resemble at all closely 

 those of any other species ; the metaparameres are short and 

 broad, and bilobed, like a finger and thumb ; the straight and 

 moderately long virga is quite simple, and not unlike that of the 

 same organ in some Pygidicranine ; but the fine dentition of the 

 preputial sac is an unusual feature in the Pygidicraninx. It is 

 highly desirable that more material be found, so that the opistho- 

 meres may be examined, and the presence or absence of gonapo- 

 physes in the female be determined (PI. IX. fig. 1). 



Family LABIDURID^:. 



My limitation of this group differs but little from that of 

 Zacher. I propose to remove the Allostethin/i 'to the Pygidicranidte, 

 as we have seen, and to include the Apachyidze, suppressing the 

 sub-order Paradcrmaptera of Verhoeff. As Zacher has shown, the 

 genitalia and general structure are suggestive of Labidurine 

 affinities; the two most striking features, the extreme flattening 

 of the body, and the fusion of the opisthomeres into a squamopy-
