the tegrnen causes us at present to put it, as exceptional, 

 along with Oedemeridae. 



Family RHIPIPHORIDAE. 



Form examined : Emcnadia sp. ? Australia. 

 Fig. 192 PI. LXXI. 



Median lobe long, slender, membranous, supported by a thin 

 chitin rod on eacli side which meet together at the base. Tegmen of 

 the Mordellid type. Internal sac undifferentiated. 



This is the same type as Mordellidae (excl. Anaspis). 



Family CANTHARIDAE = MELOIDAE. 



Forms examined : Tegrodcra erosa Lee, California. 

 Cissifes (^Horia) dcbi/i Fairm., Borneo. Nemognatha sp.* 

 Fig. 193 PL LXXI. 



Horia (Cissites) dehyi (PL LXXI fig. 193). 



Median lobe large, flattened laterally, and bent nearly at right- 

 angles one-third from base, the whole organ being pistol-shape ; 

 median orifice at apex, and median foramen occupying the ventral 

 base of basal tliird. Tegmen consisting of a large "tambour" 

 shaped basal-piece, and a single median piece, rounded at the 

 apex, representing the lateral lobes. Internal sac undifferentiated. 



Tegrodcra crosa. 



Median lobe tubular, flattened laterally, with the median 

 orifice on dorsal aspect at tip and median foramen occupying the 

 ventral aspect of the basal half ; on the ventral aspect near tip 

 are two spines, one in front of the other. Tegmen composed of a 

 large rounded and curved basal-piece and a pair of lateral lobes 

 consolidated at their base. Internal sac small with a strong curved 

 spine at its base. 



Nemognatha sp. 



Median lobe tubular with a large median foramen occupying the 

 ventral aspect of the basal half. Tegmen with lateral lobes con- 

 solidated to tip, which is roundly bilobed, basal-piece large. Internal 

 sac well developed, but without armature.

 now exists.
