Suborder I u L i d e a. 

 Family Cambalidae. 



In vol. xxxiii. of the Ann. Miis. Genova, pp. 388-389, I 

 proposed to unite the genera Cambala, Olyphiulus, and Trachy- 

 iulus. But provisionally, at all events, perhaps they may be 

 recognized until more intermediate forms come to light. More- 

 over, I have thought it admissible to add two more genera to 

 the series. The five that are now known may be recognized 

 by the following key : — 



a. The segmeuts of the body furnished with as 



many as 20 longitudinal crests, the crests on 

 each side extending to the base of the legs ; 

 tirst tergite at most onlj^ carinate behind; 

 with 4 or 5 crests on the dorsum of the 

 segments. 

 o^ With 4 dorsal crests, the median one obso- 

 lete ; all the crests undivided, the areas 



between them smooth and polished Camhala, Gray. 



Type annulata (Say). 

 6'. With 5 dorsal crests lying between the pore- 

 bearing crests. 

 a-. First tergite as in Camhala, not carinate 



above Camhalopsis, nov. 



Type calviis (Poc). 

 h^. First tergite carinate above in its posterior 



half Trachyiulus, Pet. 



Type ceylonicus (Pet.). 



b. Segments furnished with from 9 to 12 keels, 



the area above the base of the legs not keeled ; 

 fir.st tergite completely covered with carinas ; 

 with 3 (4) crests on the dorsum of the seg- 

 ments. 

 a^. Segments with 11 (12) bituberculiform 

 crests — three on each side below the pori- 

 ferous crest, and on the dorsal area three 



tubercles behind and four in front Glyphiulus, Gerv. 



Type granulatus, Gerv. 

 h^. Segments with only 9 crests, three between 

 the poriferous crests and two on each side 



below them Camhalomorpha, nov. 



Type _/brmos«, .sp. n. 



The genera Cambala and Trachyiulus contain, I believe, 

 but one species each. In addition to calvus^ I refer to Cam- 

 halopsis the Sumatra species cavernicola and dentata recently 

 referred by me to the genus Camhala. Camhalomorpha 

 contains the three enumerated below.
