T. iNTERTEXTA. General characters of T. intri<ata. Frontal base obtusely 

 impressed, basal angles of the pronotum rectangular; hunneral angles obtusely 

 rounded ; abdomen sub-opaque, punctures indistinct. 5 lines long. 



California, Joshua Child. 



Distinguished from T. intricata by beinir more slender, by having the protho- 

 rax more transverse, with the sides more sinuous, the antennce a little longer, a 

 deeper emargination at the base of the elytra and prothorax, the punctures of the 

 elytra more ru.ose, and the opacity of the abdomen, and less distinctness of its 

 punctures. 



Belostoma impressum Hald. Variegated dark and pale brown, neurations of 

 the elytra varied with black, with a black stigma at the medial point where they 

 cross. Head short, pronotum sinuous at base, sides sub-sinuous, transverse line 

 rectilinear and obtusely impressed, a fovea in front of it on each side. Two 

 fovere forming conjointly a V-shaped medial mark at the apex of the pronotum. 

 Scutel with two quadrangles of raised lines, one on each side, the raised dorsal 

 line being common to the two. Inferior surface flavous, mottled with pale 

 brown. Medial and posterior femora and tibine with three dark bands ; anterior 

 femora robust, simple, the down confined to the anterior margin; caudal appen- 

 dages not protruded. 23 lines long, 9 wide. 



California, Joshua Child. 



Allied to B. Jtaldfmaiium Leidy, but distinguished by the dorsal impressions, 

 the lighter color of the inferior surface, and the comparative narrowness of the 

 posterior tibice and tarsi. 



Zaitha inde.ntata Hahl. Broadly oval, depressed, dark brown, finely sca- 

 brous. Head, pronotum and scutel with indistinct patches of very short prostrate 

 flavous hair. Pronotum pyramidal, lateral and anterior margin with an im- 

 pressed line; apex sinuous, apical angle obtusely rounded, sides rectilinear, 

 base sub-rectilinear, dorsal line raised posteriorly, and impressed anteriorly, 

 transverse posterior line distinctly impressed, portion posterior to it, and ante- 

 rior portion of the scutel, transversely rugulose; a well impressed fovea (having 

 a raised margin) on each side equidistant between the dorsal line and exterior 

 and anterior margins, a second shallow fovea on each side of the dorsal line 

 anteriorly, conjointly forming a V-shaped figure. Disc of the scutel with irre- 

 gular rugce radiating backwards and outwards, medial line impressed. Elytra 

 with distinct cupreous reflexions, neurations very distinct. Feet with lines of 

 silky hair, their surface and the inferior parts of the body covered with short 

 prostrate hair. Length 15, width 8 lines. 



California, Dr. Le Conte. 



A second specimen has two longitudinal flavous lines on each sifle of the base. 

 The latter is a female, and the posterior part of the body above is covered 

 with ova. 



Distinguished from Z. blfoventa Hald. Stansbury's Expedition, 370, tab. 10, 

 fig. 1, bv its darker color, broader form, and the greater distinctness of the foveas 

 on the pronotum. 



PiiALANGOPsis sc'ABRiPES JTahl. Flavous mottled with black, especially upon 

 the posterior margin of all the s?<iments, knee joints of all the feet and base of 

 the antenna?, brown. Upp^^r extremity of the femora strongly curved inwards 

 toward the base ; externally and above regularly reticulate with blackish, and 

 scabrous with raised points, which arc mostly confined to the dark portions; 

 under margin with a row of small spines enlarsiing posteriorly. Length 5 H 

 lines, antenna 48, posterior femora 1 1, tibiae 12.j, tarsi Ah. One specimen taken 

 at Selma, Alabama, by Dr. Hendree. 



Resembles PJi. lapidicula Burmeister, and graeilipes Hald. (Am. Assoc. 1849, 

 p. 33G,) in size, but ditTers from the former by the smaller femoral spines, and 

 from the latter by the scabrous femora. 



Xya mixta JTald., Shining flavo.is variegated with brown. Antennm brown, 

 head flavous pimctate, more sj)arsely above, labrum and a large frontal macula 

 black. Prothorax small and transverse. Elytra flavous, base and apex brown.
