NOSODENERIEvE. — CYATHOCERIDiE.

Europe, seven or eight occurring in North and Central America, 

 and one in Ceylon. They have been included by many authors 

 under the Byrrhice, which they closely resemble in general 

 form, retractile legs, grooved femora and tibiae, etc. ; they are, 

 however, distinguished from them by the 

 formation of the head and inentum and 

 especially by their larvae, which are quite 

 different from those of the Byrrhid^e. 

 Lacordaire (G-en. et Spec. Col. ii, p. 478) 

 seems to be of the opinion that they 

 ought hardly to be placed near the 

 Byrriiidjs, but knows of no better posi- 

 tion. Thomson (Skand. Col. iv, p. 154) 

 assigns them a position among the 

 NrriDULiDiE, between Cryptarcha and 

 Thymalus ; but in the form of the legs 

 and coxaej wing-venation, etc., they are 

 widely separated from this family. 



The larva of: Nosodendron fasciculare 

 is very peculiar ; it has been noticed by 

 other authors, but a very full description 

 with an excellent figure is given by 

 Ganglbauer (Kafer Mitt. Eur. iv, 1, 



r . , r 7 7 p. 89). It is rather large compared

(After Ganglbauer.) in length, and it is broad in pro- 

 portion ; the chief peculiarities are the 

 stalked stigmata, which are situated on tubercles, the dorsal 

 position of the first and terminal position of the second abdominal 

 pairs, and the broad somewhat recurved processes at the sides of 

 the first seven abdominal segments. The sculpture also is peculiar : 

 the eighth segment is long and pear-shaped and bears no cerci ; 

 the general shape is somewhat onisciform. 



The species as a rule live at and about the running sap of 

 wounded trees ; M. meocicanum, however, occurs in muddy places. 



[Family 51. C Y ATH O CERIDiE. ] 



11 Minute insects of broad form ; parts of the mouth concealed; 

 antennce four-jointed; tarsi not divided into joints; prosternum 

 small " (Sharp). 



One species only (Oyathocerus horni) is known of this family, 

 which is very anomalous and aberrant, and nothing is known as 

 to its life-history ; it occurs in Central America. Dr. Sharp 

 (Cambridge Nat. Hist, vi, p. 243) places it between the Byrrhid^e 

 and GrEORYSSIlLE.
