rounded lobes of sternum vii are bigger and more protruding pos- 

 teriorly. From insignis, new species, to which it is also allied, 

 longiventris differs in its smaller size, different proportions of the 

 antennal segments, and having the basal two-thirds of lateral margins 

 of the scutellum denticulated. 



Calisius aiistralis, new species 



Figure 15 



Female: Head as long as wide through the eyes (18:18); anterior 

 process almost ovate, anteriorly rounded, at the base slightly con- 

 stricted, roughly granulated, reaching to the tip of the 3d antennal 

 segment; antenniferous spines acute, strongly divaricate, scarcely 

 reaching the tip of the first segment; eyes big, semiovate, protruding; 

 postocular spines small, tuberculiform, not reaching the outer margins 

 of the eyes; infraocular carina e each formed by three erect tubercles. 

 Vertex flat, with V-shaped row of granules. Antennae slender, the 

 first segment subcylindrical, the 2d ovate, the 3d slightly tapering 

 toward the base, the 4th fusiform; proportions of the antennal seg- 

 ments (1 to 4) 3:3}^:4:7K. Rostrum slightly shorter than the rostral 

 groove. 



Pronotum much shorter than wide across the humeri (19:34); 

 anteriorly truncate; collum well marked and provided with two (1 + 1) 

 big, erect tubercles; lateral margins converging anteriorly slightly 

 constricted medially. Fore disc with two (1 + 1) erect tubercles, 

 followed by four (2+2) divergent rows of similar tubercles, continued 

 on the hind disc. Lateral margins of the fore lobe each with three big, 

 blunt teeth. Hind lobe inflated and coarsely punctured; disc with 

 four (2 + 2) rows of erect tubercles; the inner rows are subparallel, the 

 outer ones curved; humeri each with a double row of similar tubercles. 



Scutellum longer than wide at the base (47 : 27) ; the basal triangular 

 elevation very high ; middle of base provided with a transverse, curved 

 row of four depressed tubercles, and the disc with four additional very 

 big tubercles, of which the inner ones are semideflated, the outer ones 

 erect. The median ridge with a row of dense, erect tubercles. The 

 lateral margins with a row of erect teeth along the basal half; at the tip 

 of the scutellum are placed two (1 + 1) small tubercles. The disc is 

 roughly punctured. 



Abdomen elongately ovate (59:40), with the connexivum obliquely 

 raised ; the lateral borders with a double row of smaller, rather obliter- 

 ated tubercles, more obliterated in the dorsolateral than in the ventro- 

 lateral row. Spii-acles of segments ii-vi ventral, placed far from the 

 lateral margin, those of vii dorsolateral, each placed on the apex of a 

 tubercle; those of the genital lobes (viii) terminal. Ijobes of segment 

 VIII granulated, divergent, reaching the middle of ix, the latter slightly
