i54 HOMOPTERA 



figure for the type species clearly shows the petiolate apical cell of the tegmina which makes such an 

 assignment impossible. Ball (igSi) called attention to this fact and correctly placed the genus in the 

 tribe Telamonini, not only on the basis of FowIer's figure and description but on the study of species 

 of the genus which he had taken in Arizona. 



The insects of this genus bear a strong superficial resemblance to the larger forms of Cyrtolobus but 

 differ in having the metopidium broadly rounded without a raised carina, and in having the tegmina only 

 about one-third exposed. Phylogenetically the genus is probably more closely related to Archasia, de- 

 scribed as the next genus in this list. Head subquadrate, smooth, more than twice as wide as high ; base 

 sinuate and only shghtly arcuate ; eyes ovate ; oceni prominent, equidistant from each other and from the 

 eyes and situated about on a line drawn through centersof eyes; inferior margins of genaebroadly sinuate; 

 clypeus semi-circular, extending not at all below inferior margins of genas. Pronotum elevated but vary- 

 ing greatly in the shape of the crest, which is sometimes high and tectiform and sometimes rounded ; met- 

 opidium broadly rounded, sloping, wider than high; median carina obsolete on metopidium but usually 

 strong on dorsum; humeral angles broad and rounded; sides of pronotum punctate but not ridged; pos- 

 terior process tectiform, just about reaching the tips of the tegmina. Tegmina only about one-third 

 exposed; basal area coriaceous and punctate; apical area hyaline; three longitudinal veins proceeding 

 from the base of the corium and continuing to the apex; two discoidal cells of which the interior is the 

 longer and dilated at the apex; apical limbus well developed. Legs simple; hind tarsi longest. 



Ball has taken both nymphs and adults of the type species tecligera and reports that the species is 

 extremely variable in size, height of crest and color. 



Type ieciigera Fowler. 



Geographical distribution : The only known species of this genus havebeen found in Mexico 

 and Arizona. F"our species have been described and Ball believes that they are all one species, but we 

 prefer to list three of them, at least until we have had more material for study.

Archasia Stal, Bid. Hem. Syst. 556 (1867). 



Characters : A very distinct genus characterized by the high, arcuate, fohaceous pronotum. 

 Head subovate, broader than high; base highly arcuate and sinuate; eyes large and ovate; ocelli small, 

 not conspicuous, much nearer to each other than to the eyes and situated below a line drawn through 

 centers of eyes; inferior margins of genas sinuate; clypeus indistinctly trilobed, the middle lobe extend- 

 ng forabout one-third its length below the inferior margins of the genag. Pronotum elevated in a high, 

 arcuate, foliaceous dorsal crest, highest in front and gradually arcuate to near the end of the posterior 

 process; metopidium vertical above the head or slightly overhanging in front, triangular, keeled; median 

 carina strongly percurrent; humeral angles weak, rounded, not prominent; sides of pronotum punctate 

 but not carinate, extended downward to cover about one-half of the tegmina ; posterior process triangular, 

 tectiform, sharply keeled, not reaching the tips of the tegmina. Tegmina about half exposed; hj'aline; 

 base sparingly punctate ; five apical and two discoidal cells; apical limbus broad. Legs simple, angular 

 in cross-section ; hind tarsi slightly longer than the others.
