I am unable to state as to whether it is a penis-sheath or the 

 tip of an ovipositor. 



SlTARIDA QUADRILOBA, 11. sp. 



Deep black, in places shining. Sparsely clothed with 

 greyish pubescence. 



Head rather strongly transverse, dilated from eyes to 

 near base ; with dense and rather strong punctures through- 

 out; with a shallow median depression, and one behind each 

 eye, thus dividing the base into four obtuse lobes. Eyes 

 very unevenly divided. Antennae short, first joint about as 

 long as three following combined, second and third short, 

 fourth stouter and larger, fifth to tenth briefly serrated, 

 eleventh moderately long. Prothorax slightly wider than the 

 median length, narrowest at apex and irregularly increasing 

 in width to base, which is wider than head and irregularly 

 lobed; surface somewhat uneven, with a vague longitudinal, 

 and two still more vague transverse impressions; punctures 

 somewhat coarser and more rugose than on head. Scutellum 

 narrowly grooved along middle and notched at apex. Elytra 

 about as long as head and prothorax combined, sides rather 

 strongly incurved, apex less than half the width of base; 

 densely rugulose punctate, punctures smaller than on head 

 and very small about apex ; with three obtuse costae. Length, 

 16-18 mm. 



Hab. — South Australia: Mount Lofty (S. H. Curnow). 

 Type, I. 3207. 



The figure ( 9 ) of Sitarida minor will give a good general 

 idea of this insect, but it differs from the description of that 

 species in the entire upper-surface of the head being densely 

 punctate, and nowhere smooth, the third joint of antennae 

 shorter than the fourth, and prothorax without smooth tuber- 

 cular elevations. The eyes are almost completely divided, 

 only a single row of facets (invisible from most directions) 

 joining the two lobes. From, the preceding species it is sharply 

 distinguished by the shape of the head and prothorax. Two 

 of the three specimens before me have the shoulders feebly 

 diluted with red.

Palasstrida bicolor, White. 



I concur with the late Rev. T. Blackburn as to the 

 synonymy of this species, but believe in addition that bicolor
