I. Dolichocysta venusta, sp. n. (PI. II., figs. 1 ; la, profile.) 



Broad oval, short, dull ; fuscous, the pronotuin with the areolae at 

 the sides in front and behind, the areolae of the hood in part, the tip 

 of the posterior process, and the three carinse, a broad blackish patch 

 on the median one excepted, more or less whitish and subhyaline ; 

 the elytra greyish, with a spot on the discoidal area before the apex, 

 a patch on the costal area before the middle, and some spots or 

 some of the nervures before and beyond it, black, the other portions 

 of the costal area whitish and subhyaline with pale nervures, the 

 nervures on the rest of the elytra blackish or fuscous ; the antennae 

 testaceous, with the outer half of the apical joint black ; the legs 

 testaceous, the femora black or piceous in the middle. Antennae 

 with joints 1 and 2 stouter than the others, 2 much shorter than 1, 

 3 very slender and elongate, 4 lanceolate and pilose, about as long 

 as 1 and 2 united. Pronotum closely punctured on the disc ; the 

 membranous margins with 3—4 rows of small areolae ; the median 

 carina strongly, the two outer carinae feebly, foliaceous, the 

 latter sinuous and connected anteriorly with a layer of mem- 

 brane which fills the space outside the base of the hood ; hood 

 extending beyond the head, narrowed and strongly curved down- 

 wards in front, rather widely reticulated. Elytra a little wider than 

 the pronotum ; discoidal, subcostal, and sutural areas (the margin 

 of the latter excepted) closely reticulated ; costal area slightly re- 

 curved, with larger areolae, the two rows diminishing to one at the 

 apex.

Hcd). — Lower California, Guadalupe {Bilimck, in 

 mus. Vind. Cms.). 



Three examples, two of which are from Guadalupe, the 

 other without definite locality. The insect is not included 

 in Prof Uhler's list of Hemiptera Heteroptera of Lower 

 California [Proc. Calif Acad. Sci. (2) iv, pp. 223-295 

 (1894)]. 



CORYTHUCHA, Stal. 



Numerous closely allied American species belong to 

 this genus. Monanthia lucida,Wa,\k. (— G.fuscigera, Still), 

 and Tingis sjiinosa, A. Duges, both from Mexico, also 

 appertain here. Stal's type of C. fuscomacidata, from 

 Brazil, is figured on Plate II, fig. 2. This last-mentioned 

 insect is extremely like G.fuscigera, Stal, but it appears to 

 have the apical margin of the elytra less rounded, the 

 inner portion being oblique.
