June, 1917] American Tingidce 305 



Color: General color j];rayish, with fuscous markings. Body beneath 

 brownish, the thorax darker brown. Legs brownish, the tips of tarsi 

 infuscated. Antennae brownish. Pronotum brownish. Elytra grayish- 

 brown, with a transverse costal band in front of constriction, another 

 near apex, and a few apical spots fuscous. 



Described from a specimen from Colorado, but without a 

 definite locality and date, probably Fort Collins, 1898. 



Genus Alveotingis Osborn and Drake. 



In this genus the subcostal, discoidal, and sutural areas are 

 either partially defined, poorly defined, or entirely undiffer- 

 entiated. The third antennal segment is more or less densely 

 clothed with decumbent hairs and thickened towards the 

 apex. In the macropterous specimens the elytra are broadly 

 rounded at the apex, wddely overlapping, and reaching con- 

 siderably beyond the abdomen ; in the brachypterous forms the 

 inner margins of the elytra are nearly straight, slightly over- 

 lapping to the apex, and reaching a little beyond the tip of 

 the abdomen. The bucculae are contiguous anteriorly. 



The photographs of the species of Alveotingis w^ere made 

 from the type specimens and are all of the same magnification. 

 The known species of the genus may be separated by the 

 following key: 



1. Antennae short and stout, not reaching the apex of the 



posterior process of the pronotum. . . . A. brevicornis n. sp. 



Antennae longer, reaching slightly beyond the apex of the 



posterior process of the pronotum 2. 



2. Third antennal segment very long; strongly swollen; median 



and lateral pronotal carinae about equally elevated, 

 reticulate; subcostal, discoidal, and sutural areas only 

 partially or poorly defined. .A. grossocerata Osb. & Drk. 

 Third antennal segment more slender and shorter; pronotum 

 with the lateral carinae not as highly elevated as the 

 median one, the areolate indistinct in the lateral carinas; 

 subcostal, discoidal, and sutural areas wdthout the 

 sligi>.t6st trace of a boundary A. minor n. sp. 



Alveotingis minor spec. nov. 



Head a little broader than long, with the median and two posterior 

 spines depressed and the two anterior ones strongly curved and con- 

 verging. Antennas rather long, moderately slender; basal segment one 

 and a half times the length of the second; second segment short, swollen
