PANTOMORUS. 153 
Group 1.—Middle tibie of male unarmed. 
1. Pantomorus albosignatus. 
Pantomorus albosignatus, Boh. in Schénh. Gen. Cure. v. p. 943°. 
Hab. Mexico, San Luis Potosi, Saltillo in Coahuila (Dr. Palmer), Durango city, 
Iguala, Tula, Tehuacan, Mexico city (Hége), Guanajuato, Etla, Aculzingo (Sal/é). 
We have received a fair series of examples of this species from the above localities, 
and from some other localities a few single specimens that may possibly belong to it or 
to one or more distinct species; but these latter more probably are extreme varieties of 
P. albosignatus, the variation affecting the colour and markings, and even to a slight 
extent the elongation of the hind-body. One of these varieties is labelled Naupactus 
rotundipennis, Chevr., in Sallé’s collection. 
2. Pantomorus maculosus. 
Naupactus maculosus, Boh. in Schénh. Gen. Cure. vi. 1, p. 21°. 
Hab. Mxxico (mus. Sommer '). 
Iam unable to identify any of the Mexican insects we have received with this 
description, and I cannot ascertain whether the types from Sommer’s collection are 
still in existence or not. Boheman places this species next P. crinitus. 
3. Pantomorus parvulus, sp. n. 
Squamulis fuscis cinereisque variegatus, elytris setis tenuibus elongatis vestitis ; prothorace brevi. 
Long. 53-7 millim. 
Hab. Mexico, Juquila, Etla, Las Peras (Sallé), Jalapa, Cerro de Plumas (H6ge). 
This is similar to some of the varieties of small size of P. albostgnatus, but it has the 
scrobes quite slender, sharply defined behind, and passing close to the eye. The 
antenne are slender, with the third joint twice as long as thesecond. ‘The rostrum and 
head are canaliculate, the eyes moderately prominent. The thorax is short, rounded at 
the sides, covered with scales that conceal the sculpture, finely canaliculate along the 
middle; the scales are pale grey in colour, but there are three vague darker fuscous 
stripes, and there is also a very short setosity. ‘The elytra are rather narrow, the base 
scarcely broader than the base of the thorax, the shoulders not rounded, the sides very 
little curved, but becoming a little broader to behind the middle ; they bear long, erect 
~ setae, and are covered with scales, which are, over the larger part of the surface, pale 
erey or whitish, but in other parts—especially about the sutural region—are dark 
brown. ‘The under surface is clothed with whitish scales. Six specimens. 
The individuals of this species are smaller than any other Pantomorus or Naupactus 
known to me. In Sallé’s collection it was labelled ‘ Naupactus perarduus, Chevr.”
