June, i9i8.] BaRHER : CONCERNING LyG.EID.E. 57 



" Cal." in the collection of the U. S. N. M. One of the ms. names 

 of Uhler for soldalicius was ocnlatus as a specimen of that species 

 from Ornisby Co., Nevada (collection of C. F. Baker), bears a label 

 to that effect. 



Trapezonotus derivatus new species. 



Very closely related to and similarly colored as Trapeconotus caliginosus 

 Dist. but uniformly larger and the shape relatively more elongated. The 

 head is less transverse ; antennae more pilose, pronotum relatively longer ; 

 disk of anterior lobe finely and sparsely punctate with the sides not profusely 

 punctate ; lateral margins of pronotum a little more widely expanded ; these 

 margins anteriorly straighter and converging more gradually, not being so 

 abruptly rounded back of eyes, the diameter of the submargin just back of 

 eyes only a little wider than head across eyes. This species will average 

 6-6.5 mm- 



Described from four J^'s and thirteen ^"s. (Type J my collec- 

 tion.) Huachuca Mts., Ariz. — collected among dead leaves and one 

 5 from Ft. Grant. Ariz.— H. G. Hubbard collector, in the U. S. N. 

 M. Both of the above species are closely related to the European T. 

 uUricJii Fieb. T. caliginosus Dist. also occurs in the Huachuca Mts., 

 Ariz., where I took seven specimens in similar situations to the above 

 species. As indicated by Distant it varies considerably in coloration 

 of legs and antenna? as does T. dcrii'atiis. 



Trapezonotus diversus new species. 



Head, anterior lobe of pronotum, scutellum and beneath, black; narrow 

 anterior and lateral margins and posterior lobe of the pronotum, hemielytra 

 anteriorly, narrow anterior margin of pronotum, posterior angle of meta- 

 sternum and acetabulae, ochraceous ; antennae with three basal segments, ros- 

 trum and legs, ferrugineous ; apex of second and third segments and all of 

 fourth segment of antenna, sub-apex of posterior femur, piceous. Apical part 

 of corium and membrane embrowned. 



Head transverse, across eyes as wide as anterior sub-margin of pronotum 

 just back of eyes, finely punctate and provided with a rather dense coating 

 of incumbent whitish hairs ; antenniferous tubercles visible from above. 

 Antenna rather slender, finely pilose; basal segment short, exceeding apex of 

 tylus by about one-third its length, second segment one-third longer than 

 third, fourth segment about one-fourth shorter than second. Rostrum reach- 

 ing between middle coxae, second segment a little longer than third. Pronotum 

 provided with a fine coating of incumbent tawny hairs; lateral expanded pale 

 margins straight, gradually converging anteriorly, gently rounded back of 

 eyes; posterior lobe profusely punctate with fuscous; posterior margin strongly
