ARADIDAE — KORMILEV 219 



emarginate at the tip. Venter roughly punctured and with a few dis- 

 persed tubercles. 



Color: Pale yellow-brown; antennae pale yellowish, segment iv pale 

 testaceous; tubercles on the hind disc of the pronotum testaceous; 

 scutellum testaceous, with a whitish band in the shape of two hooks 

 forming an inverted V. Connexivum yellow; segment ii (the first 

 visible) entirely testaceous, segments iii-v testaceous at the anterior 

 half of the exterior border, and segments vi and vii entirely testaceous; 

 segment viii whitish. Ventral surface orange-yellow; pleiu^ae and the 

 tip of the venter testaceous; the disc of the venter whitish.

Remarks: Calisius australis, new species, is allied to annulicornis 

 Bergroth, 1913, but is smaller, color of tlie body is paler, and propor- 

 tions of the antenna! segments are different. 



Calisius hackeri, new species 



Figures 13, 14 



Calisius hackeri, new species, is so closely allied to australis, new 

 species, that I first believed it to be the opposite sex of the latter. 

 After closer examination, I found distinctive characters, which allowed 

 the two to be distinguished as separate species. 



The antenna of hackeri is relatively shorter, the ratio between the 

 length of the antennae and width of the head through the eyes being 

 38:34, as compared to only 38:37 in australis. 



The 4th segment of the antennae is distinctly shorter than the 2d 

 and 3d together (12:15), whereas in C. australis the same ratio is 15:15. 



The 2d and 3d antennal segments are ovate and wider than the first, 

 v/hile in australis they are of the same width and taper towards the 

 base, subconically. 



The postocular spines are relatively shorter, and definitely fail to 

 reach the outer margin of the eyes ; the inner rows of the tubercles on 

 the hind lobe of the pronotum have relatively smaller tubercles, five 

 in each row, while in australis they are larger and only four in each row. 



Tubercles on the basal triangular elevation of the scutellum are not 

 depressed, the two inner ones in the basal row are very low^ and smaller 

 than the outer ones, while in australis the inner tubercles are the 

 larger and all are depressed. The apical margin of the scutellum has 

 six small tubercles (3 + 3), decreasing in size from the inner to the outer 

 ones, whereas there are onl}^ two (1 + 1) very small tubercles similarly 

 located on australis; both rows of the tubercles (dorsolateral and 

 ventrolateral) on the outer borders of the abdomen are well pro-
